Description

Technical Field

[0001] This utility model relates to the field of jig processing technology, specifically a deburring device for positioning jigs. Background Technology

[0002] During the drilling process on a workpiece, a row of protruding burrs will appear at the opening. If the burrs are not removed during the use of the workpiece, the workpiece's precision will decrease, and the sharp burrs may cause injury to nearby workers. Therefore, the workpiece needs to be deburred after the machining is completed.

[0003] For example, application number CN202020412089.3 describes a deburring device for machining fixtures, belonging to the technical field of fixture processing equipment. It includes a bottom mounting plate, a fixing clamp, a support mechanism, a telescopic cylinder, a rotary motor, and an automatic adjustment mechanism. The automatic adjustment mechanism consists of an adjusting cylinder, adjusting scrapers, adjusting rods, adjusting springs, and spring fixing components. The adjusting cylinder has multiple connecting rods, and two adjusting scrapers are installed parallel to each other within the adjusting cylinder. Each adjusting scraper has an inclined guide groove. The adjusting rod is positioned between the two adjusting scrapers, with a guide component at its bottom, located in one of the two guide grooves. The top of the adjusting rod passes through the adjusting cylinder, and the adjusting spring is sleeved on the adjusting rod, positioned between the top of the adjusting cylinder and the spring fixing component. This utility model, through its automatic adjustment mechanism, can automatically adapt to the size of the workpiece hole and can tightly fit against the inner wall of the workpiece hole to remove burrs.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of manually adjusting the extension distance of the scraper during use, which is a very cumbersome process, and the fact that the scraper collides with the workpiece during deburring operations, resulting in a certain gap between the workpiece and the burrs and thus preventing more thorough removal of the burrs, the fixed position of the clamping jaws in the fixed fixture cannot be adjusted during use. Therefore, the fixed fixture can only hold a single specification of positioning fixture and cannot be adapted to other specifications of positioning fixtures, thereby reducing the practicality of the aforementioned equipment. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a deburring device for positioning fixtures, which has the advantage of auxiliary adaptation clamping. It solves the problem that the position of the clamping claws in the fixed fixture is fixed and cannot be adjusted, thus making the fixed fixture only able to clamp a single specification of positioning fixture and unable to adapt to other specifications of positioning fixtures, thereby reducing the practicality of the above-mentioned equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deburring device for a positioning fixture, comprising a base plate, a grinding device, a placement table, and grippers. The two sides of the bottom of the grinding device are fixedly connected to the two sides of the top of the base plate. The two sides of the bottom of the placement table are fixedly connected to the two sides of the top of the base plate. Four symmetrical corner grooves are provided at the four corners of the top of the placement table. The surface of the grippers is slidably connected to the inner wall of the four symmetrical corner grooves. A centering moving mechanism is fixedly connected to the top of the base plate. Connecting components are provided on the symmetrical surfaces of the grippers. Reset components are fixedly connected to the four corners of the bottom of the placement table.

[0007] As a preferred embodiment of this utility model, the centering moving mechanism includes a multi-stage electric telescopic rod, the bottom of which is fixedly connected to the top of the base plate, a central block is fixedly connected to the output end of which, a steel wire rope is fixedly connected to the bottom of the symmetrical plane of the gripper, and the other end of the steel wire rope is fixedly connected to the four sides of the central block.

[0008] As a preferred embodiment of the present invention, the connecting component includes a sliding groove, which is formed on the symmetrical plane of the gripper. A sliding rod is sleeved inside the sliding groove, and the two sides of one of the sliding rods are fixedly connected to the two sides of the inner wall of one of the four corner symmetrical grooves.

[0009] In a preferred embodiment of this utility model, the reset assembly includes a fixing plate, the top of which is fixedly connected to the four corners of the bottom of the placement platform, a tension spring is fixedly connected to the symmetrical surface of the fixing plate, and the other end of the tension spring is fixedly connected to the symmetrical surface of the outer side of the gripper.

[0010] As a preferred embodiment of this utility model, a U-shaped guide frame is fitted onto the surface of the wire rope, and the top of the U-shaped guide frame is fixedly connected to the bottom of the placement platform.

[0011] In a preferred embodiment of this invention, a linear bearing is fixedly connected to the inner wall of the slide groove, and the surface of the slide rod is slidably connected to the inner wall of the linear bearing.

[0012] As a preferred embodiment of this invention, the surface of the U-shaped guide frame is fitted with a sliding sleeve, and the surface of the sliding sleeve is in contact with the bottom of the wire rope.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up four symmetrical slots at the four corners, allows the user to place the positioning fixture on the placement table and activate the centering moving mechanism. Then, supported by the connecting components, the four grippers move along the trajectory of the four symmetrical slots towards the center point of the placement table, ultimately clamping the positioning fixture. This solves the problem of fixed gripper positions in fixed fixtures, which cannot be adjusted and thus can only clamp a single size of positioning fixture, unable to adapt to other sizes, thereby reducing the practicality of the aforementioned equipment. This invention achieves the effect of assisting in adapting and clamping.

[0015] 2. This utility model, by setting a central moving mechanism, when the user needs four grippers to move simultaneously along the trajectory of the four corner symmetrical grooves towards the center point of the placement platform, activates a multi-stage electric block to drive the central block to pull the four steel wire ropes to move simultaneously, so that the grippers slide in the four corner symmetrical grooves, thereby realizing the adjustment of the gripper position to adapt to the gripper's clamping and fixing requirements for different specifications of fixtures.

[0016] 3. By setting up a connecting component, when the gripper is pulled by the wire rope and slides along the trajectory of the four-corner symmetrical groove, the sliding groove on the gripper slides along the trajectory of the sliding rod at the same time. Thus, through the cooperation of the sliding groove and the sliding rod, the gripper is supported, so that when it is pulled by the wire rope, it can move smoothly along the trajectory of the four-corner symmetrical groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a deburring device for a positioning fixture, comprising a base plate 1, a grinding device 2, a placement table 3, and grippers 4. The two sides of the bottom of the grinding device 2 are fixedly connected to the two sides of the top of the base plate 1. The two sides of the bottom of the placement table 3 are fixedly connected to the two sides of the top of the base plate 1. Four symmetrical corner grooves 5 are provided at the four corners of the top of the placement table 3. The surface of the grippers 4 is slidably connected to the inner wall of the four symmetrical corner grooves 5. A centering moving mechanism 6 is fixedly connected to the top of the base plate 1. A connecting component 7 is provided on the symmetrical surface of the grippers 4. A reset component 8 is fixedly connected to the four corners of the bottom of the placement table 3.

[0023] refer to Figure 1 and Figure 2 The central moving mechanism 6 includes a multi-stage electric telescopic rod 61. The bottom of the multi-stage electric telescopic rod 61 is fixedly connected to the top of the base plate 1. The output end of the multi-stage electric telescopic rod 61 is fixedly connected to a central block 62. The bottom of the symmetrical plane of the gripper 4 is fixedly connected to a steel wire rope 63. The other end of the steel wire rope 63 is fixedly connected to the four sides of the central block 62.

[0024] As a technical optimization of this utility model, by setting a central moving mechanism 6, when the user needs four grippers 4 to move simultaneously along the trajectory of the four corner symmetrical grooves 5 towards the center point of the placement platform 3, the multi-stage electric block is activated to drive the central block 62 to pull the four steel wire ropes 63 to move simultaneously, so that the grippers 4 slide in the four corner symmetrical grooves 5, thereby realizing the adjustment of the position of the grippers 4 to adapt to the gripping and fixing requirements of the grippers 4 for different specifications of fixtures.

[0025] refer to Figure 3 The connecting component 7 includes a slide groove 71, which is opened on the symmetrical plane of the gripper 4. A slide rod 72 is sleeved inside the slide groove 71, and the two sides of one of the slide rods 72 are fixedly connected to the two sides of the inner wall of one of the four-corner symmetrical grooves 5.

[0026] As a technical optimization of this utility model, by setting the connecting component 7, when the gripper 4 is pulled by the wire rope 63 and slides along the trajectory of the four-corner symmetrical groove 5, the sliding groove 71 on the gripper 4 slides along the trajectory of the sliding rod 72 at the same time. Thus, through the cooperation of the sliding groove 71 and the sliding rod 72, the gripper 4 is supported, so that when it is pulled by the wire rope 63, it can move smoothly along the trajectory of the four-corner symmetrical groove 5.

[0027] refer to Figure 1 The reset assembly 8 includes a fixing plate 81. The top of the fixing plate 81 is fixedly connected to the four corners of the bottom of the placement platform 3. A tension spring 82 is fixedly connected to the symmetrical surface of the fixing plate 81. The other end of the tension spring 82 is fixedly connected to the symmetrical surface of the outer side of the gripper 4.

[0028] As a technical optimization of this utility model, by setting a reset component 8, when the gripper 4 is pulled by the wire rope 63 and moves along the trajectory of the four corner symmetrical grooves 5 towards the center point of the placement platform 3, the tension spring 82 between the gripper 4 and the fixing plate 81 is stretched accordingly, deformed and generates a rebound force. Then, when the multi-stage electric rod pushes the central block 62 to reset and the wire rope 63 is loosened, the tension spring 82 pulls the gripper 4 back to the initial state through the rebound force, so as to clamp the positioning fixture again, thereby improving the user's ease of operation.

[0029] refer to Figure 2 A U-shaped guide frame 9 is fitted on the surface of the wire rope 63, and the top of the U-shaped guide frame 9 is fixedly connected to the bottom of the placement platform 3.

[0030] As a technical optimization of this utility model, by setting up a U-shaped guide frame 9, when the wire rope 63 passes through the central block 62 and is pulled downward by the multi-stage electric telescopic rod 61, the U-shaped guide frame 9 provides a bending point for the wire rope 63, so that the four grippers 4 can be smoothly and evenly pulled backward towards the center point of the placement platform 3 by the wire rope 63.

[0031] refer to Figure 3 A linear bearing 10 is fixedly connected to the inner wall of the slide groove 71, and the surface of the slide rod 72 is slidably connected to the inner wall of the linear bearing 10.

[0032] As a technical optimization of this utility model, by setting a linear bearing 10, when the gripper 4 moves, the slide rod 72 slides in the linear bearing 10. The rolling elements of the linear bearing 10 reduce the frictional resistance between the slide rod 72 and the inner wall of the slide groove 71, so that the gripper 4 can slide more smoothly in the four-corner symmetrical groove 5.

[0033] refer to Figure 3 A sliding sleeve 11 is fitted on the surface of the U-shaped guide frame 9, and the surface of the sliding sleeve 11 is in contact with the bottom of the wire rope 63.

[0034] As a technical optimization of this utility model, by setting up a sliding sleeve 11, when the wire rope 63 is bending at the U-shaped guide frame 9, the sliding sleeve 11 replaces the U-shaped guide frame 9 to contact the wire rope 63, converting the sliding friction between the wire rope 63 and the U-shaped guide frame 9 into rolling friction, reducing the friction force, and thus improving the service life of the wire rope 63.

[0035] The working principle and usage process of this utility model are as follows: When the user needs to deburr the positioning fixture, first place the positioning fixture on the placement platform 3, then activate the multi-stage electric telescopic rod 61, driving the central block 62 to pull the four steel wire ropes 63 to move simultaneously, and let the steel wire ropes 63 bend at the bending point provided by the U-shaped guide frame 9, so that the four grippers 4, through the cooperation of the sliding groove 71 and the sliding rod 72, smoothly move along the trajectory of the four corner symmetrical grooves 5 towards the center point of the placement platform 3, and make the tension between them and the fixed plate 81... When the spring 82 is stretched, it deforms and generates a rebound force until the four grippers 4 clamp the positioning fixture. At this point, the grinding device 2 can be started to perform deburring and grinding on the positioning fixture on the placement table 3. After the processing is completed, the multi-stage electric telescopic rod 61 can be started again to push the central block 62 to move upward and reset, loosening the steel wire rope 63. Thus, the grippers 4 are reset to their initial state by the rebound force of the tension spring 82, thereby releasing the fixed clamping on the positioning fixture. Finally, the positioning fixture can be removed, thus having the advantage of auxiliary adaptation clamping.

[0036] In summary, this positioning fixture uses a deburring device. By setting four symmetrical corner grooves 5, when the user places the positioning fixture on the placement table 3, the centering moving mechanism 6 is activated. Then, supported by the connecting component 7, the four grippers 4 move along the trajectory of the four symmetrical corner grooves 5 towards the center point of the placement table 3, ultimately clamping the positioning fixture. This solves the problem of fixed gripper positions in fixed fixtures, which cannot be adjusted, thus limiting the fixed fixture to only clamping a single size of positioning fixture and making it unsuitable for other sizes, thereby reducing the practicality of the aforementioned equipment.
