Abstract

The invention provides a cam bearing cap self-locking positioning clamp, a die casting machining device and a die casting. The cam bearing cap self-locking positioning clamp comprises a rack, a clamping table and two self-locking clamping mechanisms which are oppositely arranged. A clamping position is arranged on the clamping table and used for containing the cam bearing cover. Each self-locking clamping mechanism comprises a mounting seat, a driving assembly and a locking assembly; the locking assembly comprises a positioning ejector rod and a retainer; the positioning ejector rod and the retainer are elastically and slidably arranged on the mounting seat, and an included angle is formed between the sliding direction of the retainer and the sliding direction of the positioning ejector rod. According to the self-locking positioning clamp for the cam bearing cover, the arrival time that the second end of the retainer abuts against and clamps the positioning ejector rod can be coordinated by designing the stroke of the positioning ejector rod and the stroke of the push block, so that the positioning ejector rod cannot further slide, and the self-locking function is achieved; therefore, the risk that the cam bearing cover is deformed due to the fact that the cam bearing cover is directly subjected to large acting force can be effectively avoided, and the machining precision of the assembly hole is ensured.

Description

Technical Field

[0001] The invention relates to the technical field of die casting processing, in particular to a cam bearing cover self-locking positioning fixture, a die casting processing device and a die casting. Background Art

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex metal mold. Generally, the die castings after forming cannot meet the use requirements immediately, so they need to be fine-machined, and during the fine-machining process, they need to be fixed with a fixture.

[0003] In the design process of the fixture, for the convenience of fixture manufacturing, designers usually use a clamping mechanism in a die-casting finishing fixture as disclosed in Chinese patent document CN106078290B. The above clamping mechanism is more suitable for die-castings with a relatively regular supporting bottom surface; however, for some die-castings with irregular contour surfaces, the above clamping mechanism has a poor fixing effect on the die-castings.

[0004] For example, Figure 1 The cam bearing cover 1 installed on the automobile engine is shown as a thin-walled die-casting. The cam bearing cover 1 is provided with assembly holes 2 at both ends. In the prior art, when the assembly hole 2 of the cam bearing cover 1 is finely processed, such as fine drilling, a cylinder is usually added on both sides of the clamping table of the cam bearing cover 1 to clamp and fix the cam bearing cover 1, which makes the cylinder driving force act directly on the cam bearing cover 1, which easily leads to the risk of deformation of the cam bearing cover 1, and thus the machining accuracy of the assembly hole 2 cannot be ensured. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cam bearing cover self-locking positioning fixture, die-casting processing device and die-casting part that can realize a self-locking function, thereby effectively avoiding the risk of deformation caused by the cam bearing cover being directly subjected to the cylinder driving force during the positioning and clamping process, thereby ensuring the processing accuracy of the assembly hole.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A cam bearing cover self-locking positioning fixture comprises a frame, a clamping table and two self-locking clamping mechanisms arranged opposite to each other;

[0008] The clamping platform is arranged on the frame, and a clamping position is arranged on the clamping platform, and the clamping position is used to place a cam bearing cover;

[0009] The cam is an angular movement movement mechanism which moves the locking cam of the locking cam and the locking cam of the locking cam, the cam being arranged on a pair of rotations of the locking cam and being capable of moving relative to one another.

[0010] When the telescopic end of the first telescopic driving member drives the push rod and the push block to synchronously move toward the clamping platform to the first predetermined position, the positioning push rod abuts against the end side of the cam bearing cover, and at the same time, the first end of the stop member abuts against the inclined surface and slides relative to the mounting seat, and the second end of the stop member abuts and clamps against the positioning push rod, and is in a self-locking state;

[0011] When the telescopic end of the first telescopic driving member drives the push rod and the push block to synchronously move away from the clamping platform to the second predetermined position, the positioning push rod is separated from the end side of the cam bearing cover, and at the same time, the stop member slides and resets relative to the mounting seat, and the second end of the stop member abuts and separates from the positioning push rod, and is now in an unlocked state.

[0012] In one embodiment, the mounting seat is provided with a first through hole and a first countersunk hole which are connected in sequence; one end of the positioning push rod is located in the first countersunk hole, and one end of the positioning push rod is movably sleeved with a first return spring member, the other end of the positioning push rod is slidably penetrated in the first through hole, and the other end of the push rod extends into the first countersunk hole and abuts against one end of the positioning push rod; and / or,

[0013] The sliding direction of the positioning push rod is parallel to the power output direction of the first telescopic driving member.

[0014] In one embodiment, the cam bearing cover self-locking positioning clamp also includes a buffer assembly, which includes a compression spring component and a piston block; the compression spring component and the piston block are sequentially arranged in the mounting seat, one end of the compression spring component abuts against one end of the positioning push rod, and the other end of the compression spring component abuts against the piston block, and the piston block is located between the compression spring component and the push rod.

[0015] In one embodiment, the driving assembly also includes a connecting push plate, one end of the push rod and one end of the push block are respectively connected to one side of the connecting push plate, and the other side of the connecting push plate is fixedly mounted on the telescopic end of the first telescopic driving member.

[0016] In one embodiment, the mounting seat is further provided with a second through hole and a second countersunk hole which are connected in sequence; the second through hole is connected with the first through hole; the second end of the stop member is movably sleeved with a second return spring member, the second end of the stop member is slidably connected with the second through hole, and the first end of the stop member is slidably connected with the second countersunk hole.

[0017] In one of the embodiments, a plurality of positioning supports are fixedly mounted at the clamping position, and the plurality of positioning supports are used to abut against the irregular contour surface of the cam bearing cover.

[0018] In one embodiment, the cam bearing cover self-locking positioning fixture also includes a positioning assembly, and the positioning assembly includes a first telescopic positioning member and a second telescopic positioning member; the first telescopic positioning member and the second telescopic positioning member are arranged in a one-to-one correspondence with the assembly holes at both ends of the cam bearing cover, and the first telescopic positioning member and the second telescopic positioning member are slid through the frame and the clamping table in sequence, so that one end of the first telescopic positioning member extends to the assembly hole at one end of the cam bearing cover, and one end of the second telescopic positioning member extends to the assembly hole at the other end of the cam bearing cover.

[0019] In one embodiment, the cam bearing cover self-locking positioning clamp also includes a pressing component; the pressing component includes a second telescopic driving member, a lever seat and a pressing component; the lever seat and the second telescopic driving member are both arranged on the side of the clamping platform, one end of the pressing component is rotatably connected to the lever seat and the telescopic end of the second telescopic driving member respectively, the other end of the pressing component extends to above the clamping position, and the telescopic end of the second telescopic driving member drives the other end of the pressing component to move away from or press down the cam bearing cover.

[0020] A die-casting processing device comprises the cam bearing cover self-locking positioning fixture described in any one of the above embodiments.

[0021] A die casting is obtained by processing with the die casting processing device.

[0022] Compared with the prior art, the present invention has at least the following advantages:

[0023] Since the positioning push rod and the stopper are elastically slidably arranged on the mounting seat, and there is an angle between the sliding direction of the stopper and the sliding direction of the positioning push rod, when the push rod and the push block are driven by the telescopic end of the first telescopic driving member to synchronously move toward the clamping platform to the first predetermined position, the positioning push rod abuts against the end side of the cam bearing cover, and the first end of the stopper abuts against the inclined surface and slides relative to the mounting seat, and the second end of the stopper abuts and clamps against the positioning push rod, thereby realizing self-locking of the positioning push rod; conversely, when the push rod and the push block are driven by the telescopic end of the first telescopic driving member to synchronously move away from the clamping platform to the second predetermined position, the positioning push rod leaves the end side of the cam bearing cover, and the stopper slides and resets relative to the mounting seat, and the second end of the stopper abuts and leaves the positioning push rod, thereby realizing unlocking of the positioning push rod. The cam bearing cover self-locking positioning clamp structure of the present invention is cleverly designed and has good structural compactness. It can coordinate the time when the second end of the stopper abuts against and clamps the positioning push rod by designing the stroke of the positioning push rod and the push block, so that the positioning push rod cannot slide further, thereby realizing the self-locking function, and further effectively avoiding the risk of deformation caused by the cam bearing cover being directly subjected to a large force, thereby ensuring the processing accuracy of the assembly hole.

[0043] See also Figures 1 to 11 In order to better understand the cam bearing cap self-locking positioning fixture 10 disclosed in the present invention, the cam bearing cap self-locking positioning fixture 10 is further explained below:

[0044] A cam bearing cover self-locking positioning fixture 10 of one embodiment includes a frame 100, a clamping platform 200 and two self-locking clamping mechanisms 300 arranged opposite to each other; the clamping platform 200 is arranged on the frame 100, and a clamping position 201 is provided on the clamping platform 200, and the clamping position 201 is used to place the cam bearing cover 1; each of the self-locking clamping mechanisms 300 includes a mounting seat 310, a driving assembly 320 and a locking assembly 330; the mounting seat 310 is provided with a slide groove 3101, and the mounting seat 310 is located on one side of the clamping platform 200; the driving assembly 320 includes a first telescopic driving member 3210, a push rod 3220 and a push block 3230; the first telescopic driving member 3210 is arranged on the mounting seat The mounting seat 310 is on a side away from the clamping platform 200, one end of the push rod 3220 and one end of the push block 3230 are both connected to the telescopic end of the first telescopic driving member 3210, the other end of the push block 3230 is slidably connected to the slide groove 3101, and the end of the other end of the push block 3230 is formed with an inclined surface 3232; the locking assembly 330 includes a positioning push rod 3310 and a stopper 3320, the positioning push rod 3310 and the stopper 3320 are both elastically slidably arranged on the mounting seat 310, and the sliding direction of the stopper 3320 and the sliding direction of the positioning push rod 3310 have an angle; the other end of the push rod 3220 is connected to the positioning push rod 3310;

[0045] When the telescopic end of the first telescopic driving member 3210 drives the push rod 3220 and the push block 3230 to move synchronously toward the clamping platform 200 to the first predetermined position, the positioning push rod 3310 abuts against the end side of the cam bearing cover 1, and at the same time, the first end of the stop member 3320 abuts against the inclined surface 3232 and slides relative to the mounting seat 310, and the second end of the stop member 3320 abuts and clamps against the positioning push rod 3310, and is in a self-locking state;

[0046] When the telescopic end of the first telescopic driving member 3210 drives the push rod 3220 and the push block 3230 to synchronously move away from the clamping platform 200 to a second predetermined position, the positioning push rod 3310 is separated from the end side of the cam bearing cover 1, and at the same time, the stop member 3320 slides and resets relative to the mounting seat 310, and the second end of the stop member 3320 abuts against and separates from the positioning push rod 3310, and is in an unlocked state.

[0047] In this embodiment, since the positioning push rod 3310 and the stopper 3320 are elastically slidably arranged on the mounting seat 310, and there is an angle between the sliding direction of the stopper 3320 and the sliding direction of the positioning push rod 3310, when the push rod 3220 and the push block 3230 are synchronously driven toward the clamping table 200 to the first predetermined position by the telescopic end of the first telescopic driving member 3210, the positioning push rod 3310 is abutted against the end side of the cam bearing cover 1, and at the same time, the first end of the stopper 3320 is abutted against the inclined surface and slides relative to the mounting seat 310, and finally the stopper 3320 is stopped. The second end of the moving member 3320 abuts and clamps against the positioning push rod 3310, thereby realizing self-locking of the positioning push rod 3310; conversely, when the push rod 3220 and the push block 3230 are driven by the telescopic end of the first telescopic driving member 3210 to synchronously move away from the clamping table 200 to the second predetermined position, the positioning push rod 3310 is separated from the end side of the cam bearing cover 1, and at the same time, the stop member 3320 slides and resets relative to the mounting seat 310, and finally the second end of the stop member 3320 abuts and leaves the positioning push rod 3310, thereby realizing unlocking of the positioning push rod 3310. The cam bearing cover self-locking positioning clamp 10 of the present invention has an ingenious structural design and good structural compactness. It can coordinate the time when the second end of the stopper 3320 abuts against and clamps the positioning push rod 3310 by designing the stroke of the positioning push rod 3310 and the push block 3230, so that the positioning push rod 3310 cannot slide further, thereby realizing the self-locking function, and further effectively avoiding the risk of deformation caused by the cam bearing cover 1 being directly subjected to a large force, thereby ensuring the processing accuracy of the assembly hole 2.

[0048] like Figures 3 to 5 As shown, in one embodiment, the mounting seat 310 is provided with a first through hole 3102 and a first countersunk hole 3103 which are connected in sequence; one end of the positioning push rod 3310 is located in the first countersunk hole 3103, and one end of the positioning push rod 3310 is movably sleeved with a first return spring member 3330, and the other end of the positioning push rod 3310 is slidably penetrated in the first through hole 3102, and the other end of the push rod 3220 extends into the first countersunk hole 3103 and abuts against one end of the positioning push rod 3310. In one embodiment, the sliding direction of the positioning push rod 3310 is parallel to the power output direction of the first telescopic driving member 3210.

[0049] It can be understood that in this embodiment, the central axis of the first through hole 3102 coincides with the central axis of the first countersunk hole 3103, that is, the first through hole 3102 and the first countersunk hole 3103 are connected in a straight line and penetrate the two sides of the mounting seat 310, so that the first telescopic driving member 3210 can drive the positioning push rod 3310 to slide through the push rod 3220, so that the other end of the positioning push rod 3310 abuts against the end side of the cam bearing cover 1, thereby achieving the positioning and clamping of the cam bearing cover 1. At the same time, after the first return spring member 3330 is elastically compressed, the driving force of the first telescopic driving member 3210 can be effectively slowed down, making the positioning and clamping process of the cam bearing cover 1 smoother and more stable, and effectively avoiding the risk of deformation caused by the cam bearing cover 1 being directly subjected to a large force.

[0050] Furthermore, a limiting portion 3312 is formed at one end of the positioning push rod 3310, one end of the first return spring member 3330 abuts against the end face of the limiting portion 3312, and the aperture of the first counterbore 3103 is larger than the aperture of the first through hole 3102, so that the other end of the first return spring member 3330 can abut against the bottom of the first counterbore 3103. In this way, not only the convenience of installing the first return spring member 3330 is improved, but also when the telescopic end of the first telescopic driving member 3210 drives the limiting portion 3312 to slide through the push rod 3220, the first return spring member 3330 can be moved. The spring member 3330 is compressed by force, which can effectively reduce the large driving force when the first telescopic driving member 3210 is started, thereby effectively avoiding the risk of deformation caused by the cam bearing cover 1 being directly subjected to a large force; at the same time, by providing the first return spring member 3330, the positioning push rod 3310 can have the ability of sliding return, that is, when the telescopic end of the first telescopic driving member 3210 slides out along the first countersunk hole 3103, the first return spring member 3330 drives the other end of the positioning push rod 3310 away from the end side of the cam bearing cover 1 to release the positioning clamping of the cam bearing cover 1. In this embodiment, the diameter of the limiting portion 3312 is larger than the aperture of the first through hole 3102, which has a better limiting effect.

[0051] Furthermore, an annular conical surface 3314 is formed in the middle of the positioning push rod 3310, and the annular conical surface 3314 is gradually contracted from the other end of the positioning push rod 3310 to the direction of one end of the positioning push rod 3310. In this way, when the first telescopic driving member 3210 drives the push block 3230 to slide toward the clamping table 200, the inclined surface 3232 at the other end of the push block 3230 abuts against the first end of the stopper 3320, thereby driving the second end of the stopper 3320 to gradually move upward until it abuts against the annular conical surface 3314. Specifically, when the second end of the stop member 3320 initially abuts against the annular cone surface 3314, the clamping force of the second end of the stop member 3320 is less than the sliding force of the positioning push rod 3310, and the positioning push rod 3310 continues to slide; as the first end of the stop member 3320 continues to abut and move upward along the inclined surface 3232, the clamping force of the second end of the stop member 3320 gradually exceeds the sliding force of the positioning push rod 3310, and the positioning push rod 3310 cannot continue to slide, so that the positioning push rod 3310 can position and clamp the cam bearing cover 1. It can be understood that after the positioning push rod 3310 completes self-locking, no matter the other end of the positioning push rod 3310 needs to continue to slide toward the clamping table 200 or retreat, the clamping force of the second end of the stop member 3320 needs to be overcome. It is relatively large, thereby effectively avoiding the risk of the cam bearing cover 1 being directly subjected to a large force and causing deformation. At the same time, it can also effectively prevent the clamping from loosening during the process of positioning and clamping the cam bearing cover 1 by the positioning push rod 3310, thereby ensuring the processing accuracy of the assembly hole 2.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the cam bearing cap self-locking positioning fixture 10 further includes a buffer assembly 400, and the buffer assembly 400 includes a compression spring member 410 and a piston block 420; the compression spring member 410 and the piston block 420 are sequentially arranged in the mounting seat 310, one end of the compression spring member 410 abuts against one end of the positioning push rod 3310, and the other end of the compression spring member 410 abuts against the piston block 420, and the piston block 420 is located between the compression spring member 410 and the push rod 3220. Specifically, in this embodiment, the compression spring member 410 and the piston block 420 are sequentially arranged in the first counterbore 3103.

[0053] It can be understood that by sequentially adding a compression spring member 410 and a piston block 420 between the positioning push rod 3310 and the push rod 3220, not only can the large driving force of the first telescopic driving member 3210 be further mitigated, but also the stability of the telescopic end of the first telescopic driving member 3210 when driving the positioning push rod 3310 to slide through the push rod 3220 can be improved. Furthermore, by selecting the first return spring member 3330 and the compression spring member 410 with different compression strokes for combined use, the positioning and clamping force applied by the positioning push rod 3310 to the cam bearing cap 1 can be adjusted, thereby avoiding the risk of deformation caused by the large force of the first telescopic driving member 3210 directly acting on the cam bearing cap 1.

[0054] like Figure 5 As shown, in one embodiment, the driving assembly 320 also includes a connecting push plate 3240, one end of the push rod 3220 and one end of the push block 3230 are respectively connected to one side of the connecting push plate 3240, and the other side of the connecting push plate 3240 is fixedly installed on the telescopic end of the first telescopic driving member 3210.

[0055] It can be understood that in this embodiment, the first telescopic driving member 3210 can synchronously drive the push rod 3220 and the push block 3230 to move by connecting to the push plate 3240, thereby effectively improving the utilization rate of the first telescopic driving member 3210, and further making the cam bearing cover self-locking positioning clamp 10 have better structural compactness.

[0056] like Figures 4 to 6 As shown, in one embodiment, the mounting seat 310 is further provided with a second through hole 3104 and a second countersunk hole 3105 which are connected in sequence; the second through hole 3104 is connected with the first through hole 3102; the second end of the stop member 3320 is movably sleeved with a second return spring member 3340, the second end of the stop member 3320 is slidably connected with the second through hole 3104, and the first end of the stop member 3320 is slidably connected with the second countersunk hole 3105.

[0057] It can be understood that when the first telescopic driving member 3210 drives the push block 3230 to slide toward the clamping platform 200, so that the inclined surface 3232 at the other end of the push block 3230 abuts against the first end of the stopper 3320, the first end of the stopper 3320 abuts against the inclined surface 3232 and moves upward, thereby driving the second end of the stopper 3320 to slide to the first through hole 3102 and abut against the clamping positioning push rod 3310. Similarly, when the first telescopic driving member 3210 drives the push block 3230 to slide away from the clamping platform 200, so that the inclined surface 3232 at the other end of the push block 3230 is away from the first end of the stopper 3320, at the same time, under the elastic reset force of the second reset spring member 3340, the first end of the stopper 3320 abuts against the inclined surface 3232 and moves downward, thereby driving the second end of the stopper 3320 to reduce the force applied to the positioning push rod 3310.

[0058] Furthermore, a limiting groove 3322 is provided at the first end of the stop member 3320, and the limiting groove 3322 extends along the length direction of the first end of the stop member 3320; the mounting seat 310 is also provided with a screw positioning hole 3106, and the screw positioning hole 3106 is vertically connected to the second countersunk hole 3105, and the screw positioning hole 3106 is used to install a limiting screw, and the end of the limiting screw extends to the limiting groove 3322. In this way, it is possible to effectively prevent the second end of the stop member 3320 from transitioning upward and causing the positioning push rod 3310 to become stuck, and at the same time, it is possible to prevent the stop member 3320 from falling off from the second countersunk hole 3105 under the elastic reset force of the second return spring member 3340, thereby improving the structural rationality of the cam bearing cover self-locking positioning clamp 10, so as to effectively ensure that the stop member 3320 can realize the self-locking function of the positioning push rod 3310, and further effectively avoid the risk of the cam bearing cover 1 being directly subjected to a large force and causing deformation, thereby ensuring the processing accuracy of the assembly hole 2.

[0059] Furthermore, the first end of the stopper 3320 is the large end of the stopper 3320, the second end of the stopper 3320 is the small end of the stopper 3320, and the diameter of the large end of the stopper 3320 is larger than the diameter of the small end of the stopper 3320. In this way, it is convenient to movably sleeve the second return spring member 3340 on the small end of the stopper 3320, and the large end of the stopper 3320 forms an installation limit for the second return spring member 3340, which effectively improves the installation convenience of the second return spring member 3340, and at the same time makes the structure of the stopper 3320 and the mounting seat 310 more compact.

[0060] It should be noted that there is an angle between the sliding direction of the stopper 3320 and the sliding direction of the positioning push rod 3310, that is, there is an angle between the central axis of the first through hole 3102 and the central axis of the second through hole 3104. In this embodiment, the central axis of the first through hole 3102 and the central axis of the second through hole 3104 are set at a 90-degree angle, so that the second end of the stopper 3320 can slide to the first through hole 3102 and abut against the positioning push rod 3310. Of course, this is not limited here, and those skilled in the art can also make other choices as needed.

[0061] like Figures 1 to 3 As shown, in one of the embodiments, the clamping position 201 is fixedly mounted with a plurality of positioning support members 210 , and the plurality of positioning support members 210 are used to abut against the irregular contour surface S of the cam bearing cover 1 .

[0062] It is understandable that Figure 1 and Figure 2 As shown, the cam bearing cover 1 is an arched structure, and the cam bearing cover 1 has two planes 3 to be processed. Therefore, when the cam bearing cover 1 is placed on the clamping position 201, the two planes 3 to be processed of the cam bearing cover 1 are arranged upward, and abut against the irregular contour surface S of the cam bearing cover 1 through multiple positioning support members 210, so that it can be ensured that the assembly hole 2 of the cam bearing cover 1 and the two planes 3 to be processed can be finely processed at the same time.

[0063] like Figures 1 to 3 As shown, in one embodiment, each of the positioning support members 210 is detachably connected to the clamping platform 200. In this way, it is convenient to replace positioning support members 210 of different specifications, so that the irregular contour surface S of the cam bearing cap 1 can be well adapted to ensure the position accuracy of the cam bearing cap 1 placed in the clamping position 201, thereby ensuring the processing accuracy of the assembly hole 2 and the two planes to be processed 3. Specifically, in this embodiment, the positioning support member 210 and the clamping platform 200 are screwed, that is, the lower end of the positioning support member 210 is provided with an external threaded portion, and the clamping platform 200 is provided with an internal threaded hole. Through the threaded connection between the external threaded portion and the internal threaded hole, the height of the upper end of the positioning support member 210 from the clamping platform 200 can be adjusted, so that the placement of cam bearing caps 1 of different specifications and sizes can be adapted under the joint abutment of multiple positioning support members 210. In other embodiments, the positioning support member 210 and the clamping platform 200 can also be clamped, thereby improving the convenience of installing the positioning support member 210.

[0064] like Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, in one embodiment, the cam bearing cover self-locking positioning fixture 10 also includes a positioning assembly 500, and the positioning assembly 500 includes a first telescopic positioning member 510 and a second telescopic positioning member 520; the first telescopic positioning member 510 and the second telescopic positioning member 520 are arranged in a one-to-one correspondence with the assembly holes 2 at both ends of the cam bearing cover 1, and the first telescopic positioning member 510 and the second telescopic positioning member 520 are slid through the frame 100 and the clamping platform 200 in sequence, so that one end of the first telescopic positioning member 510 extends to the assembly hole 2 at one end of the cam bearing cover 1, and one end of the second telescopic positioning member 520 extends to the assembly hole 2 at the other end of the cam bearing cover 1.

[0065] It can be understood that since the first telescopic positioning member 510 and the second telescopic positioning member 520 are slid through the frame 100 and the clamping platform 200 in sequence, and the first telescopic positioning member 510 and the second telescopic positioning member 520 are arranged in a one-to-one correspondence with the assembly holes 2 at both ends of the cam bearing cover 1; therefore, when the cam bearing cover 1 is placed in the clamping position 201, by aligning the assembly hole 2 at one end of the cam bearing cover 1 with one end of the first telescopic positioning member 510, and aligning the assembly hole 2 at the other end of the cam bearing cover 1 with one end of the second telescopic positioning member 520, the cam bearing can be aligned. The placement of the cover 1 plays a role of pre-positioning to effectively ensure the position accuracy of the cam bearing cover 1; then, the cam bearing cover 1 is positioned and clamped by the positioning push rods 3310 of the two oppositely arranged self-locking clamping mechanisms 300; finally, the first telescopic positioning piece 510 withdraws from the assembly hole 2 at one end of the cam bearing cover 1, and the second telescopic positioning piece 520 withdraws from the assembly hole 2 at the other end of the cam bearing cover 1, thereby effectively avoiding the problem of tool collision between the assembly holes 2 at both ends of the cam bearing cover 1 during the fine machining process, thereby ensuring the machining accuracy of the assembly holes 2.

[0066] like Figure 3 , Figure 7 and Figure 8 As shown, in one embodiment, the cam bearing cover self-locking positioning fixture 10 also includes a pressing component 600; the pressing component 600 includes a second telescopic driving member 610, a lever seat 620 and a pressing component 630; the lever seat 620 and the second telescopic driving member 610 are both arranged on the side of the clamping platform 200, one end of the pressing component 630 is rotatably connected to the telescopic end of the lever seat 620 and the second telescopic driving member 610 respectively, and the other end of the pressing component 630 extends to the top of the clamping position 201, and the telescopic end of the second telescopic driving member 610 drives the other end of the pressing component 630 to move away from or press down the cam bearing cover 1.

[0067] It should be noted that two self-locking clamping mechanisms 300 arranged opposite to each other and a clamping table 200 constitute a cam bearing cover 1 processing station; specifically, in this embodiment, the cam bearing cover self-locking positioning fixture 10 has two cam bearing cover 1 processing stations to effectively improve the efficiency of the cam bearing cover 1 finishing.

[0068] It can be understood that the telescopic end of the second telescopic driving member 610 is pushed upward by utilizing the principle of leverage to drive the other end of the pressing member 630 to press down the cam bearing cover 1, thereby effectively ensuring the stability of the clamping and positioning of the cam bearing cover 1; on the contrary, when the telescopic end of the second telescopic driving member 610 is retracted downward by utilizing the principle of leverage to drive the other end of the pressing member 630 away from the cam bearing cover 1, the pressing member 630 releases the downward pressure applied to the cam bearing cover 1. Furthermore, in the present embodiment, the number of the second telescopic driving member 610 is one, the number of the lever seat 620 and the number of the pressing member 630 are both two, the two lever seats 620, the two pressing members 630 and the one second telescopic driving member 610 are all arranged between the two cam bearing cover 1 processing stations, so that the second telescopic driving member 610 can simultaneously drive the two pressing members 630 to respectively press down and clamp the cam bearing covers 1 on the two cam bearing cover 1 processing stations, so as to effectively improve the efficiency of the fine processing of the cam bearing covers 1, and make the pressing assembly 600 have better structural compactness than the vertical clamping mechanism in the engine transition connecting plate positioning tooling disclosed in the Chinese patent document CN107738126B, and at the same time, the second telescopic driving member 610 can use the lever principle to drive the pressing member 630 to press down and clamp the cam bearing cover 1 more labor-saving, and the pressing stability of the pressing member 630 is better, so as to further ensure the processing accuracy of the assembly hole 2.

[0069] like Figure 3 , Figure 7 and Figure 8 As shown, in one embodiment, the frame 100 is provided with a hollow position 101 , and the second telescopic driving member 610 , the other end of the first telescopic positioning member 510 , and the other end of the second telescopic positioning member 520 are all arranged in the hollow position 101 .

[0070] It can be understood that the telescopic end of the second telescopic driving member 610 slides through the frame 100 and extends between the two cam bearing cover 1 processing stations; wherein, the other end of the first telescopic positioning member 510 and the other end of the second telescopic positioning member 520 are both located below two oppositely arranged self-locking clamping mechanisms 300, thereby effectively improving the space utilization of the frame 100 and making the cam bearing cover self-locking positioning fixture 10 of the present invention more compact and ingenious.

[0071] Further, the second telescopic driving member 610 includes a lifting cylinder 6110, a telescopic rod 6120 and a sliding guide sleeve 6130; the lifting cylinder 6110 is arranged in the hollow position 101, one end of the telescopic rod 6120 is connected to the power output end of the lifting cylinder 6110, and the other end of the telescopic rod 6120 is slidably penetrated through the inner hole of the sliding guide sleeve 6130 to the side of the clamping platform 200, and is rotatably connected with one end of the pressing member 630. It can be understood that by adding the sliding guide sleeve 6130 to effectively ensure that the other end of the telescopic rod 6120 has good stability and wear resistance during the sliding process, so that the lifting cylinder 6110 drives the pressing member 630 to press down through the telescopic rod 6120. The stability is better, and the cam bearing cover 1 can be effectively prevented from being positioned loose, so that the processing accuracy of the assembly hole 2 can be further ensured.

[0072] Furthermore, if Figure 7 and Figure 8 As shown, in one embodiment, the first telescopic positioning member 510 includes a first positioning column 5110, a first connecting seat 5120 and a first cylinder 5130; one end of the first positioning column 5110 slides through the frame 100 and the clamping platform 200 in sequence, and extends to the assembly hole 2 at one end of the cam bearing cover 1, the first connecting seat 5120 is fixedly installed on the power output end of the first cylinder 5130, the first connecting seat 5120 is provided with a first clamping hole 5122, and the other end of the first positioning column 5110 is formed with a first clamping portion 5112, and the first clamping portion 5112 is clamped into the first clamping hole 5122;

[0073] The second telescopic positioning member 520 includes a second positioning column 5210, a second connecting seat 5220 and a second cylinder 5230; one end of the second positioning column 5210 slides through the frame 100 and the clamping platform 200 in sequence, and extends to the assembly hole 2 at the other end of the cam bearing cover 1, the second connecting seat 5220 is fixedly installed on the power output end of the second cylinder 5230, the second connecting seat 5220 is provided with a second clamping hole 5222, and the other end of the second positioning column 5210 is formed with a second clamping portion 5212, and the second clamping portion 5212 is clamped into the second clamping hole 5222.

[0074] It can be understood that in this embodiment, the first cylinder 5130, the first connecting seat 5120, the second cylinder 5230 and the second connecting seat 5220 are all arranged in the hollow position 101, so that the first cylinder 5130 drives the first positioning column 5110 to slide through the frame 100 and the clamping table 200 through the first connecting seat 5120, and the second cylinder 5230 drives the second positioning column 5210 to slide through the frame 100 and the clamping table 200 through the second connecting seat 5220, thereby achieving the role of pre-positioning the placement of the cam bearing cap 1, so as to effectively ensure the position accuracy of the placement of the cam bearing cap 1;

[0075] Furthermore, by driving the cylinder, the sliding response rate of the first positioning column 5110 and the second positioning column 5210 can be improved, thereby effectively improving the efficiency of positioning, clamping and finishing of the cam bearing cover 1.

[0076] Furthermore, since the depths of the assembly holes 2 of cam bearing covers 1 of different specifications and sizes are different, in order to ensure that the first positioning column 5110 and the second positioning column 5210 can be withdrawn from the assembly hole 2 of the cam bearing cover 1 more accurately, the assembly holes 2 at both ends of the cam bearing cover 1 are prevented from colliding with the tool during the fine machining process, thereby ensuring the machining accuracy of the assembly holes 2.

[0077] In one embodiment, the cam bearing cover self-locking positioning fixture 10 further includes a detection reset assembly 700, and the detection reset assembly 700 includes an I-shaped support seat 710, a horizontal plate 720 and a detection rod 730; the I-shaped support seat 710 is arranged in the hollow position 101, the first cylinder 5130 and the second cylinder 5230 are sequentially arranged on the top of the I-shaped support seat 710, the horizontal plate 720 is erected between the first cylinder 5130 and the second cylinder 5230, and the two ends of the horizontal plate 720 are respectively connected to the power output end of the first cylinder 5130 and the power output end of the second cylinder 5230;

[0078] Among them, the detection rod 730 is fixedly installed on the horizontal plate 720, and a gas detection channel 7101 is opened on the top of the I-type support seat 710. The end of the detection rod 730 is aligned with one port of the gas detection channel 7101, and the other port of the gas detection channel 7101 is connected to the gas detection device.

[0079] It can be understood that since the cross plate 720 is mounted between the first cylinder 5130 and the second cylinder 5230, and the two ends of the cross plate 720 are respectively connected to the power output end of the first cylinder 5130 and the power output end of the second cylinder 5230, when the first cylinder 5130 and the second cylinder 5230 synchronously drive the first positioning column 5110 and the second positioning column 5210 to slide downward to exit the assembly hole 2 of the cam bearing cover 1, the cross plate 720 will move with the first positioning column 5110 and the second positioning column 5210, thereby driving the detection rod The end of 730 abuts against a port of the air inspection channel 7101, so that the air inspection device detects the change of the air pressure in the air inspection channel 7101, converts the above-mentioned air pressure change signal into an electrical signal and transmits it to the PLC program control system, and controls the first cylinder 5130 and the second cylinder 5230 to stop moving through the PLC program control system, so as to judge that the first positioning column 5110 and the second positioning column 5210 have been reset to their positions, that is, to ensure that the first positioning column 5110 and the second positioning column 5210 can be completely withdrawn from the assembly hole 2 of the cam bearing cover 1.

[0080] It should be noted that the working principle of the gas detection device using a gas sensor for detection and the working principle of the PLC program control system controlling the first cylinder 5130 and the second cylinder 5230 belong to the prior art and will not be introduced in detail here.

[0081] Furthermore, in order to improve the positioning effect of the cam bearing cover 1 when it is placed in the clamping position 201 for positioning and clamping, the machining accuracy of the assembly hole 2 is ensured.

[0082] like Fig.10 and Fig.11 As shown, in another embodiment, the cam bearing cover self-locking positioning fixture 10 also includes a clamping and limiting assembly 800; the clamping and limiting assembly 800 includes a guide seat 810, a slider 820 and a contoured chuck 830; the guide seat 810 is provided with a guide through hole 8101, and the guide seat 810 is located between the self-locking clamping mechanism 300 and the clamping platform 200, and the slider 820 and the contoured chuck 830 are slidably arranged in the guide through hole 8101 in sequence, one end of the slider 820 is connected to the other end of the positioning push rod 3310, and the other end of the slider 820 is detachably connected to the contoured chuck 830, and the contoured chuck 830 is used to abut and limit the end side of the cam bearing cover 1.

[0083] It can be understood that the contoured chuck 830 can be contoured according to the outer contour of the end side of the cam bearing cover 1, so that when the positioning push rod 3310 pushes the slider 820 and the contoured chuck 830 to slide toward the end side of the cam bearing cover 1, the contoured chuck 830 can better clamp the cam bearing cover 1; moreover, the other end of the slider 820 is detachably connected to the contoured chuck 830, so that the user can replace the contoured chuck 830 of different shapes according to the outer contour of the end side of the cam bearing cover 1, so as to adapt to the clamping and positioning of the cam bearing cover 1 with different shapes and contours, thereby effectively improving the adaptability of the cam bearing cover self-locking positioning clamp 10.

[0084] Furthermore, two spring members are installed between the other end of the slider 820 and the profiling chuck 830, so that the other end of the slider 820 forms an elastic connection with the profiling chuck 830. In this way, a sufficient sliding gap can be reserved between the guide through hole 8101 and the profiling chuck 830, so that the profiling chuck 830 has a margin for automatically adjusting the deflection when it is abutted and clamped to the end side of the cam bearing cap 1, thereby effectively avoiding the risk of deformation caused by excessive clamping (excessive squeezing) of the cam bearing cap 1 by the profiling chuck 830, thereby ensuring the processing accuracy of the assembly hole 2.

[0085] The present application also provides a die-casting processing device, comprising the cam bearing cover self-locking positioning fixture 10 described in any of the above embodiments.

[0086] In this embodiment, the die-casting processing device uses the above-mentioned cam bearing cover self-locking positioning fixture to position and clamp the cam bearing cover and then perform finishing operations, thereby effectively avoiding the risk of deformation caused by the cam bearing cover being directly subjected to a large force, thereby ensuring the processing accuracy of the assembly hole.

[0087] The present application also provides a die-casting part, which is processed by using the above-mentioned die-casting processing device.

[0088] Compared with the prior art, the present invention has at least the following advantages:

[0089] Since the positioning push rod and the stopper are elastically slidably arranged on the mounting seat, and there is an angle between the sliding direction of the stopper and the sliding direction of the positioning push rod, when the push rod and the push block are driven by the telescopic end of the first telescopic driving member to synchronously move toward the clamping platform to the first predetermined position, the positioning push rod abuts against the end side of the cam bearing cover, and the first end of the stopper abuts against the inclined surface and slides relative to the mounting seat, and the second end of the stopper abuts and clamps against the positioning push rod, thereby realizing self-locking of the positioning push rod; conversely, when the push rod and the push block are driven by the telescopic end of the first telescopic driving member to synchronously move away from the clamping platform to the second predetermined position, the positioning push rod leaves the end side of the cam bearing cover, and the stopper slides and resets relative to the mounting seat, and the second end of the stopper abuts and leaves the positioning push rod, thereby realizing unlocking of the positioning push rod. The cam bearing cover self-locking positioning clamp structure of the present invention is cleverly designed and has good structural compactness. It can coordinate the time when the second end of the stopper abuts against and clamps the positioning push rod by designing the stroke of the positioning push rod and the push block, so that the positioning push rod cannot slide further, thereby realizing the self-locking function, and further effectively avoiding the risk of deformation caused by the cam bearing cover being directly subjected to a large force, thereby ensuring the processing accuracy of the assembly hole.

[0090] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
