Description

Technical Field

[0001] This invention belongs to the field of engine cylinder block manufacturing, specifically a tool holder and tool holder connection structure for engine cylinder block manufacturing. Background Technology

[0002] The cutter head placement device used in engine block manufacturing is a device for storing and retrieving cutter heads. It typically consists of a cutter head holder and clamping mechanism. Engine block manufacturing is a complex process involving multiple stages and different types of machining operations. Multiple cutter heads are used in the manufacturing process. When a cutter head needs to be replaced, the conventional practice is to place the old cutter head into the cutter head placement device and remove the new cutter head from the device.

[0003] A patent application with publication number CN206382924U discloses a placement device for replacing the cutter head during the manufacturing process of an engine cylinder block. The device includes a bracket, a tray, and a mounting plate. A guide rod at the bottom of the tray passes through the mounting plate and is inserted into a guide cylinder. A limiting device is provided on the bracket to restrict the rotation of the tray. This placement device can place the cutter head to be replaced without damaging it.

[0004] The above technical solutions still have some problems in practical application. When assembling the cutter head and the connecting structure together, and placing the two as a whole on machine tools or other equipment or in a cutter head placement device, it is necessary to ensure the connection is stable and that the cutter head does not wobble or loosen. The cutter head generally has an L-shaped mounting hole, through which the connecting structure passes and supports the cutter head. The connecting structure and the mounting hole fit tightly. For different cutter heads, the diameter of the mounting hole is different. Conventional methods require the preparation of connecting structures of different sizes, which is time-consuming, labor-intensive, and costly. In order to prevent the cutter head from wobbling up and down, bolts and other fasteners are also required to fix the cutter head, which is cumbersome. The above technical solutions have not effectively solved this problem.

[0005] Therefore, the present invention provides a tool holder for replacing the tool disc and a tool disc connection structure for manufacturing engine cylinder blocks. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a cutter head connection structure, comprising: a connecting rod for supporting the cutter head component, the connecting rod being L-shaped, the connecting rod including a base plate and a vertical rod, the vertical rod having an assembly hole; a fastening nut threadedly connected to the vertical rod; and a conical ring fixed to the bottom end of the fastening nut, the conical ring being sleeved on the outside of the vertical rod.

[0008] Preferably, the system further includes several sets of dispersing mechanisms, which are evenly distributed in a ring around the base plate. Each dispersing mechanism includes: an abutment plate movably inserted into the ring side of the base plate; and a return spring for driving the abutment plate closer to the base plate.

[0009] Preferably, the dispersing mechanism further includes: a slide groove in the base plate, the slide groove being L-shaped; a transmission assembly on the abutment plate; a drive rod movably inserted into the top of the base plate, the top end of the drive rod being movably connected to the conical ring, the drive rod and the transmission assembly respectively sealing both ends of the slide groove; and a filler placed inside the slide groove, through which the drive rod and the transmission assembly are transmitted.

[0010] Preferably, the transmission assembly includes: a fixed plate fixed to the abutment plate; a movable plate slidably disposed at the top of the fixed plate; a positioning rod movably inserted into the movable plate; and a positioning groove formed on the top of the fixed plate and corresponding to the positioning rod.

[0011] Preferably, the dispersing mechanism further includes: a pressure plate movably inserted into the end of the fixed plate; a support spring provided on the pressure plate; and a push plate fixed to the pressure plate, wherein the push plate moves into the fixed plate and drives the positioning rod to move to separate from the positioning groove.

[0012] Preferably, the dispersing mechanism further includes a flow divider plate fixed in the chute, the flow divider plate being located between the fixed plate and the movable plate, the flow divider plate being used to separate the filler, and a gap being left between the flow divider plate and the drive rod.

[0013] Preferably, it further includes: a locking nut threadedly connected to the vertical rod, the locking nut being located above the fastening nut, and the bottom end of the locking nut having a ring plate; and a locking washer sleeved on the outside of the locking nut, the locking washer being located between the conical ring and the ring plate.

[0014] Preferably, the outer side of the conical ring is provided with a polygonal plate, and the top of the conical ring is provided with a limiting ring for limiting the locking washer, the limiting ring being located outside the fastening nut.

[0015] A replacement cutter head placement device for engine cylinder block manufacturing, the device being applied to the cutter head connection structure described above, comprising: a turntable; a plurality of support plates rotatably mounted on the turntable; and a clamping mechanism mounted on the support plates for clamping the connecting rod.

[0016] Preferably, the clamping mechanism includes: a plurality of grippers movably inserted into the periphery of the support plate, the top of each gripper having a beveled edge, and the sidewall of the abutment plate having a slope; a spring for driving the grippers closer to the support plate; a round rod fixed to the grippers; and a rotating ring rotatably disposed on the support plate, the rotating ring having a plurality of through slots, the through slots being inclined, the round rod being inserted into the through slots, and the rotating ring rotating to drive the plurality of grippers to move synchronously through the round rod and the through slots.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The cutter head connection structure of the present invention, by setting a fastening nut and a conical ring, rotates the fastening nut to lower the conical ring until the conical ring abuts against the inner wall of the vertical hole. At the same time, the conical ring and the base plate abut against the upper and lower ends of the cutter head component, respectively, so that the cutter head component and the connecting rod are kept stable in both the horizontal and vertical directions. It is simple to operate and convenient to use. By adjusting the upper and lower height of the conical ring, it can adapt to cutter head components with different vertical hole sizes, which has good applicability, saves the trouble of manufacturing connecting rods of various sizes, and reduces the cost of use.

[0019] 2. The cutter head connection structure of the present invention, by setting a dispersion mechanism, when the fastening nut is rotated, the conical ring drives the drive rod to move downward. The drive rod drives the transmission component and the abutment plate to move outward through the filler. After the abutment plate abuts against the side wall of the bottom hole, the positioning state of the movable plate is automatically released. A part of the filler continues to provide pushing force to the fixed plate, so that the abutment plate stably abuts against the side wall of the bottom hole. A part of the filler and the movable plate move outward so that the conical ring and the drive rod can continue to move downward until the conical ring abuts against the vertical hole. The bottom plate is connected to the bottom hole through the abutment plate, thereby dispersing the force, improving the problem of force concentration, and extending the service life of the connecting rod.

[0020] 3. The cutter head connection structure of the present invention can simultaneously fix the vertical rod and the base plate by simply tightening the fastening nut. It is suitable for mounting holes of different sizes, and the filler has a stepless adjustment function, making it more versatile.

[0021] 4. The engine cylinder block manufacturing tool changer placement device of the present invention, by setting a clamping mechanism on a rotatable support plate, after the connecting rod loaded with the tool changer is placed on the support plate from top to bottom, the jaws automatically clamp the bottom plate, thereby improving the stability of the connecting rod and the tool changer on the support plate; since the jaws do not clamp the tool changer, the tool changer can be disassembled and assembled on the support plate without disassembling the connecting rod, which is convenient to use.

Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figure 1-4 As shown in the figure, a cutter head connection structure according to an embodiment of the present invention includes: a connecting rod 1, the connecting rod 1 being used to support the cutter head component 100, the connecting rod 1 being L-shaped, the connecting rod 1 including a base plate 11 and a vertical rod 12, the vertical rod 12 having an assembly hole 13; a fastening nut 2 threadedly connected to the vertical rod 12; and a conical ring 3 fixed to the bottom end of the fastening nut 2, the conical ring 3 being sleeved on the outside of the vertical rod 12.

[0038] Specifically, the cutter head component 100 has a mounting hole in the shape of an L. The mounting hole includes a bottom hole 101 and a vertical hole 102. The ring side of the vertical rod 12 has a threaded section. The assembly hole 13 is located above the threaded section. The connecting rod 1 is installed on the assembly station of the machine tool through the assembly hole 13. The machine tool is equipped with fastening devices such as pins that are inserted into the assembly hole 13. When the cutter head component 100 is installed on the machine tool or other equipment through the connecting structure, the cutter head component 100 and the connecting rod 1 need to be assembled together first. During assembly, the cutter head component 100 is placed on the connecting rod 1, the vertical rod 12 passes through the vertical hole 102 and the bottom plate 11 abuts against the inner top wall of the bottom hole 101. The assembly hole 13 in the vertical rod 12 is located above the cutter head component 100. Then the connecting rod 1 is assembled on the machine tool.

[0039] The outer diameter of the vertical rod 12 in the connecting rod 1 must be matched with the inner diameter of the vertical hole 102 to prevent the cutter head 100 from swaying horizontally relative to the vertical rod 12. For different cutter head 100s, the diameter of the vertical hole 102 in the mounting hole is different. Conventional methods require the preparation of connecting rods 1 of different sizes, which is time-consuming, labor-intensive, and costly. In order to prevent the cutter head 100 from swaying up and down with the connecting rod 1, in conventional methods, multiple bolts and other fasteners are installed at the bottom of the base plate 11, which is troublesome to operate.

[0040] During the use of this connection structure, when assembling the cutter head component 100, the cutter head component 100 is first placed on the connecting rod 1, and the top plate of the base plate 11 is pressed tightly against the inner top wall of the vertical hole 102. The fastening nut 2 is rotated to lower the conical ring 3 until the conical ring 3 abuts against the inner wall of the vertical hole 102. At the same time, the conical ring 3 and the base plate 11 abut against the upper and lower ends of the cutter head component 100 respectively, thereby keeping the cutter head component 100 and the connecting rod 1 stable in both the horizontal and vertical directions. The operation is simple and convenient. By adjusting the upper and lower height of the conical ring 3, it can adapt to cutter head components 100 with different vertical hole 102 sizes, which has good applicability and saves the trouble of preparing connecting rods 1 of various sizes, thus reducing the cost of use.

[0041] like Figure 2-6As shown, it also includes several sets of dispersing mechanisms 4, which are evenly distributed in a ring along the base plate 11. Each dispersing mechanism 4 includes: an abutment plate 41 that is movably inserted into the ring side of the base plate 11; and a return spring 411 for driving the abutment plate 41 closer to the base plate 11.

[0042] Specifically, the abutment plate 41 can move laterally. In the initial state, the abutment plate 41 is close to the base plate 11 so that the base plate 11 can be inserted into the bottom hole 101.

[0043] For different cutter head components 100, the inner diameter of the bottom hole 101 in the mounting hole is also different. The side wall of the base plate 11 does not contact the side wall of the bottom hole 101. In the traditional connection structure, the circumferential side wall of the base plate 11 abuts against the side wall of the bottom hole 101. After the cutter head component 100 is assembled with the connection structure, the connecting rod 1 is mainly connected to the cutter head through the vertical rod 12. During operation, the cutter head component 100 and the connecting rod 1 rotate at high speed. Since the circumferential side of the base plate 11 is not supported, the centrifugal force and other forces generated during the rotation are mainly concentrated in the vertical rod. The connection between the rod 12 and the vertical rod 12 and the base plate 11 is prone to aggravating fatigue wear of the vertical rod 12, and the vertical rod 12 and the base plate 11 are also prone to breakage. To address this issue, a dispersion mechanism 4 is provided. By adjusting the position of the abutment plate 41, the abutment plate 41 is made to abut against the side wall of the bottom hole 101, and then the abutment plate 41 is fixed in place. The base plate 11 is connected to the bottom hole 101 through the abutment plate 41, thereby dispersing the force, improving the problem of force concentration, and extending the service life of the connecting rod 1.

[0044] like Figure 2-6 As shown, the dispersing mechanism 4 further includes: a groove 42 in the base plate 11, the groove 42 being L-shaped; a transmission assembly 43 on the abutment plate 41; a drive rod 44 movably inserted into the top of the base plate 11, the top of the drive rod 44 being movably connected to the conical ring 3, the drive rod 44 and the transmission assembly 43 respectively sealing both ends of the groove 42; and a filler 45 placed inside the groove 42, through which the drive rod 44 and the transmission assembly 43 are transmitted.

[0045] Specifically, the direction of movement of the abutment plate 41 away from the base plate 11 is outward movement, and vice versa; the filler 45 is preferably, but not limited to, steel balls, and other materials with flexibility and shaping function, such as fine sand, are also suitable for manufacturing the filler 45; the drive rod 44 can move up and down, and the bottom end of the cone ring 3 is provided with an annular groove. The bottom end of the drive rod 44 is inserted into the groove. When the fastening nut 2 is rotated, the cone ring 3 rotates and moves up and down at the same time. At the same time, the cone ring 3 drives the drive rod 44 to move up and down. After the drive rod 44 moves down, it drives the transmission component 43 and the abutment plate 41 to move outward through the filler 45, so that the abutment plate 41 abuts against the side wall of the bottom hole 101. In this way, after the fastening nut 2 is tightened, the cone ring 3 and the abutment plate 41 simultaneously fix the vertical rod 12 and the base plate 11. Moreover, the filler 45 has a stepless adjustment function, which makes it more applicable.

[0046] like Figure 2-6 As shown, the transmission assembly 43 includes: a fixed plate 431 fixed to the abutment plate 41; a movable plate 432 slidably disposed at the top of the fixed plate 431; a positioning rod 433 movably inserted into the movable plate 432; and a positioning groove 434 formed on the top of the fixed plate 431 and corresponding to the positioning rod 433.

[0047] Specifically, the positioning rod 433 can move up and down. In the initial state, the positioning rod 433 is inserted into the positioning groove 434, so that the movable plate 432 and the fixed plate 431 form a whole.

[0048] For different cutter head components 100, the inner diameter of the bottom hole 101 in the mounting hole is also different. For the bottom hole 101 with a smaller inner diameter, before the cone ring 3 moves down and abuts against the inner wall of the vertical hole 102, the abutment plate 41 has already abutted against the side wall of the bottom hole 101, which will prevent the cone ring 3 and the drive rod 44 from moving down further, so that the cone ring 3 cannot abut against the inner wall of the vertical hole 102. Therefore, the travel of the transmission assembly 43 needs to be adjusted. In order to improve this problem, the transmission assembly 43 is set as a fixed plate 431 and a movable plate 432 that can be fixed and separated.

[0049] When the abutment plate 41 abuts against the side wall of the bottom hole 101 and the conical ring 3 does not abut against the inner wall of the vertical hole 102, the positioning rod 433 moves upward to release the positioning state of the movable plate 432. Then, the conical ring 3 and the drive rod 44 continue to move downward. The drive rod 44 drives the movable plate 432 to continue to move outward through the filler 45. During the movement of the movable plate 432, the fixed plate 431 and the abutment plate 41 remain in a stable position under the push of the filler 45. In this way, the drive rod 44 can drive the abutment plate 41 to stably abut against the side wall of the bottom hole 101 without affecting the continued downward movement of the conical ring 3. When using this connection structure, the conical ring 3 can be used for vertical holes 102 of different sizes, and the transmission component 43 and the abutment plate 41 can be used for bottom holes 101 of different sizes. Therefore, this connection structure is suitable for the assembly of cutter head parts 100 of different sizes and has good applicability.

[0050] like Figure 2-6 As shown, the dispersing mechanism 4 further includes: a pressure plate 46 movably inserted into the end of the fixed plate 431; a support spring 461 provided on the pressure plate 46; and a push plate 47 fixed to the pressure plate 46. After the push plate 47 moves into the fixed plate 431, it drives the positioning rod 433 to move until it is separated from the positioning groove 434.

[0051] Specifically, the support spring 461 is used to drive the pressure plate 46 to move inward. In the initial state, the pressure plate 46 and the fixed plate 431 are kept relatively stable in position by the support spring 461; the top of the push plate 47 is provided with a ramp for pushing the positioning rod 433 upward.

[0052] When assembling the cutter head component 100 and the connecting rod 1, the cutter head component 100 is placed on the connecting rod 1, and the fastening nut 2 is rotated. The fastening nut 2 causes the conical ring 3 to move downward, and the conical ring 3 causes the drive rod 44 to move downward. The drive rod 44, through the filler 45, causes the pressure plate 46, the fixed plate 431, and the movable plate 432 to move outward together. The fixed plate 431 causes the abutment plate 41 to move outward. After the abutment plate 41 abuts against the side wall of the bottom hole 101, the conical ring 3 and the drive rod 44 continue to move downward, and the fixed plate... When the pressure on the pressure plate 46 in 431 increases, the filler 45 pushes the pressure plate 46 to move outward. After the pressure plate 46 moves outward, the push plate 47 drives the positioning rod 433 to move upward, so that the positioning rod 433 separates from the positioning groove 434. Then, a part of the filler 45 and the movable plate 432 move outward so that the cone ring 3 and the drive rod 44 can continue to move downward. A part of the filler 45 continues to provide pushing force to the fixed plate 431, so that the abutment plate 41 stably abuts against the side wall of the bottom hole 101.

[0053] like Figure 3-4As shown, the dispersing mechanism 4 also includes a diverter plate 48 fixed in the chute 42. The diverter plate 48 is located between the fixed plate 431 and the movable plate 432. The diverter plate 48 is used to separate the filler 45. A gap is left between the diverter plate 48 and the drive rod 44.

[0054] Specifically, with Figure 4 Taking the left side slide 42 as an example, the diversion plate 48 is located between the movable plate 432 and the fixed plate 431. The right side section of the separation plate does not exceed the bottom groove in the slide 42. The filler 45 is divided into upper and lower parts within the bottom groove range of the slide 42. After the positioning rod 433 separates from the positioning groove 434, the upper part of the filler 45 can drive the movable plate 432 to move independently.

[0055] like Figure 1-7 As shown, it also includes: a locking nut 5 threadedly connected to the vertical rod 12, the locking nut 5 being located above the fastening nut 2, and the bottom end of the locking nut 5 being provided with a ring plate 51; and a locking washer 6 sleeved on the outside of the locking nut 5, the locking washer 6 being located between the conical ring 3 and the ring plate 51.

[0056] Specifically, the locking washer 6 is used to prevent the fastening nut 2 from loosening. The locking washer 6 adopts a double washer locking structure. The upper and lower side walls of the washer are respectively provided with cams and serrations. The cams and serrations are in opposite directions. The two washers are centrally symmetrically distributed. The cams of the upper and lower washers are in contact with each other. The locking washer 6 is pressed on top of the fastening nut 2, and the ring plate 51 is pressed on top of the locking washer 6.

[0057] When assembling the cutter head component 100 and the connecting rod 1, the cutter head component 100 is placed on the connecting rod 1, and the fastening nut 2 is rotated so that the conical ring 3 abuts against the inner wall of the vertical hole 102 and the abutment plate 41 abuts against the side wall of the bottom hole 101. Then, the locking nut 5 is rotated so that the locking nut 5 moves down. The locking nut 5 locks the fastening nut 2 through the locking washer 6 to prevent the fastening nut 2 from loosening, thereby improving the assembly firmness of the conical ring 3 and the cutter head component 100. After the position of the conical ring 3 is stabilized, the abutment plate 41 is also stabilized through the transmission of the drive rod 44 and the filler 45. Therefore, the assembly firmness of the whole device can be improved.

[0058] like Figure 2-7 As shown, the outer side of the conical ring 3 is provided with a polygonal plate 31, and the top of the conical ring 3 is provided with a limiting ring 32 for limiting the locking washer 6. The limiting ring 32 is located outside the fastening nut 2.

[0059] Specifically, after the locking nut 5 moves down, the locking washer 6 is pressed by the ring plate 51, so that the locking washer 6 is tightly attached to the limiting ring 32. When disassembling the cutter head component 100, since the fastening nut 2 is located inside the limiting ring 32, the fastening nut 2 can be loosened by rotating the polygonal plate 31, making the operation more convenient.

[0060] Working principle: When assembling the cutter head component 100 and the connecting rod 1, the cutter head component 100 is placed on the connecting rod 1, and the fastening nut 2 is rotated, causing the conical ring 3 to move downward. The conical ring 3 drives the drive rod 44 to move downward. The drive rod 44, through the filler 45, drives the pressure plate 46, the fixed plate 431, and the movable plate 432 to move outward together. The fixed plate 431 drives the abutment plate 41 to move outward. After the abutment plate 41 abuts against the side wall of the bottom hole 101, the conical ring 3 and the drive rod 44 continue to move downward. The pressure on the pressure plate 46 in the fixed plate 431 increases, and the filler 45 pushes the pressure plate 46 outward. After the pressure plate 46 moves outward, it drives the positioning rod 433 to move upward through the push plate 47, so that the positioning rod 433 separates from the positioning groove 434. Then, part of the filler 45 and the movable plate 432 move outward so that the cone ring 3 and the drive rod 44 can continue to move downward. Part of the filler 45 continues to provide pushing force to the fixed plate 431, so that the abutment plate 41 stably abuts against the side wall of the bottom hole 101. After the cone ring 3 abuts against the inner wall of the vertical hole 102, the locking nut 5 is rotated so that the locking nut 5 moves downward. The locking nut 5 locks the fastening nut 2 through the locking washer 6 to prevent the fastening nut 2 from loosening.

[0061] Example 2

[0062] like Figure 1-10 As shown in the embodiment of the present invention, a replacement cutter head placement device for engine cylinder block manufacturing is applied to the cutter head connection structure described above, including: a turntable 7; a plurality of support plates 8 rotatably disposed on the turntable 7; and a clamping mechanism 9 disposed on the support plates 8 for clamping the connecting rod 1.

[0063] Specifically, the turntable 7 is movably mounted on the machine tool, and the machine tool is provided with an assembly station for mounting the cutter head component 100; the cutter head component 100 and the connecting rod 1 are placed on each support plate 8 respectively, one of the support plates 8 is in an empty state, and the connecting rod 1 is fixed on the turntable 7 by the clamping mechanism 9.

[0064] When replacing the cutter head component 100, move the turntable 7 so that the empty support plate 8 is moved to the assembly station below the machine tool. Remove the old cutter head component 100 and connecting rod 1 from the machine tool and place them into the empty support plate 8. Then rotate the turntable 7 so that the new cutter head component 100 is rotated to the assembly station below the assembly station. Install the connecting rod 1 with the new cutter head component 100 into the assembly station. Finally, remove the turntable 7. In this way, the quick replacement of the cutter head component 100 can be completed.

[0065] like Figure 9-10 As shown, the clamping mechanism 9 includes: a plurality of grippers 91 movably inserted into the periphery of the support plate 8, the top of each gripper 91 having a beveled edge, and the side wall of the abutment plate 41 having a slope; a spring member 92 for driving the grippers 91 closer to the support plate 8; a round rod 93 fixed to the grippers 91; and a rotating ring 94 rotatably disposed on the support plate 8, the rotating ring 94 having a plurality of through slots 95, the through slots 95 being inclined, the round rod 93 being inserted into the through slots 95, and the rotating ring 94, after rotating, driving the plurality of grippers 91 to move synchronously through the round rod 93 and the through slots 95.

[0066] Specifically, the gripper 91 moves inward when it approaches the support plate 8, and outward when it moves away. Multiple grippers 91 move synchronously inward or outward through a rotating ring 94.

[0067] When the connecting rod 1, which is loaded with the cutter head component 100, is placed on the support plate 8 from top to bottom, two situations may occur: First, the bottom plate 11 in the connecting rod 1 contacts the gripper 91, while the abutment plate 41 does not contact the gripper 91. In this case, the bottom plate 11 presses the gripper 91 outward, and the gripper 91 automatically clamps the bottom plate 11, thereby fixing the connecting rod 1 on the support plate 8; Second, the abutment plate 41 contacts the gripper 91, and the abutment plate 41 pushes the gripper 91 and the support plate 8 to rotate together through the side wall ramp, so that the gripper 91 separates from the abutment plate 41 and clamps the bottom plate 11. If part of the connecting rod 1 contacts the gripper 91 and part of the abutment plate 41 contacts the gripper 91 at the same time, there is a problem that the gripper 91 is unstable in clamping the connecting structure. By setting a rotatable support plate 8, the gripper 91 is ensured to clamp the base plate 11, which improves the above problem and enhances the stability of the connecting rod 1 and the cutter head 100 placed on the support plate 8. Since the gripper 91 only clamps the base plate 11 and does not clamp the cutter head 100, the cutter head 100 can be disassembled and assembled on the support plate 8 without disassembling the connecting rod 1, which is convenient to use.
