Description

Technical Field

[0001] This utility model relates to the field of non-standard tooling technology, specifically a high-precision self-conducting non-standard tooling. Background Technology

[0002] Non-standard tooling is short for "non-standard process equipment". It is a highly targeted and customized production tool in the manufacturing industry. It is designed strictly according to the structural characteristics of specific products, the technical requirements of special processes, or the actual needs of exclusive production scenarios. It completely breaks through the limitations of general standards and specifications and aims to solve complex production problems that standardized tools cannot handle. It is mainly used to assist in product production, processing, assembly, testing and other processes.

[0003] In the prior art, Chinese Patent Publication No. CN208495979U discloses a non-standard tooling fixture that facilitates machine tool cutting of workpieces. The fixture includes a worktable, with a placement plate and a fixing frame fixedly mounted on the upper outer surface of the worktable. The fixing frame is located on both sides of the placement plate. A connecting frame is fixedly mounted on the upper outer surface of the fixing frame, and a motor is fixedly mounted on the upper outer surface of the connecting frame. A thick rod is fixedly mounted on the lower outer surface of the connecting frame, and a thin rod is movably connected inside the thick rod. A connecting plate is fixedly mounted on the lower outer surface of the thin rod, and a cutting blade is movably connected to the lower outer surface of the connecting plate. This allows for easy replacement of the cutting blade, improving cutting performance. It also allows for adjustment of the fixing plate's position, prevents debris from flying, protects user health, and offers better application prospects.

[0004] Based on the above information, existing non-standard tooling makes it very troublesome to fix the workpiece during cutting, and the fixation is not secure, which can easily cause the workpiece to shake. Furthermore, it cannot move the workpiece according to the cutting requirements. Therefore, we propose a high-precision self-conducting non-standard tooling. Utility Model Content

[0005] The purpose of this utility model is to provide a high-precision self-conducting non-standard tooling to solve the problems mentioned in the background art, such as the difficulty in fixing the workpiece during cutting, the unreliable fixing of the workpiece, the easy shaking of the workpiece, and the inability to move the workpiece according to the cutting needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision self-conductive non-standard tooling, comprising a worktable and a mounting block. A fixed seat is slidably mounted on the outer wall of the worktable. The outer wall of the fixed seat is provided with a fixing mechanism for fixing the workpiece. The fixing mechanism includes a fixed block fixedly mounted on the outer wall of the fixed seat, and a first drive motor is fixedly mounted on the outer wall of the fixed block. A bidirectional screw is fixedly mounted on the output end of the first drive motor, and a slider is threadedly mounted on the outer wall of the bidirectional screw. A support rod is rotatably mounted on the outer wall of the slider. A pressing plate slidably mounted on the outer wall of the fixed block and rotatably connected to the end of the support rod is rotatably mounted. A driving bevel gear is fixedly mounted on the end of the bidirectional screw. A drive shaft is rotatably mounted on the outer wall of the mounting block, and a driven bevel gear is fixedly mounted on the end of the drive shaft. A moving mechanism for adjusting the position of the fixed seat is provided inside the worktable.

[0007] Furthermore, the fixed seat has a rectangular cross-section, the fixed blocks are equidistantly distributed on the top outer wall of the fixed seat, and the distance between the two sets of fixed blocks is greater than the width of the workpiece.

[0008] Furthermore, the length of the bidirectional screw is greater than the distance between the two sets of fixing blocks, and two sets of bidirectional screws are symmetrically arranged, with the sliders symmetrically arranged on the outer wall of the bidirectional screw.

[0009] Furthermore, the extrusion plate is located between the two sets of fixed blocks, and the outer wall of the fixed block is provided with a sliding groove corresponding to the extrusion plate. The bottom outer wall of the extrusion plate is provided with pads at equal intervals, and the pads are made of rubber. The outer wall of the pads is in contact with the outer wall of the workpiece. The inner wall of the fixed block is fixedly installed with a guide rod that is slidably connected to the extrusion plate, and the outer wall of the guide rod is sleeved with an extrusion spring.

[0010] Furthermore, the drive shaft is located between the two sets of bidirectional screws, and the driven bevel gears are symmetrically arranged on the outer wall of the drive shaft, and the driven bevel gears are meshed with the driving bevel gears.

[0011] Furthermore, the moving mechanism includes a moving block fixedly installed at the bottom of the fixed base, a second drive motor fixedly installed at the end of the worktable, and an adjusting screw fixedly installed at the output end of the drive motor. A moving groove is provided on the outer wall of the worktable, and a sliding rod is fixedly installed on the inner wall of the moving groove.

[0012] Furthermore, the moving block has an inverted U-shaped cross-section, and the moving groove is correspondingly set to the moving block, with the length of the moving groove corresponding to the moving range of the moving block.

[0013] Furthermore, the length of the adjusting screw is set to correspond to the length of the moving groove, and the outer wall of the adjusting screw is threadedly connected to the moving block. Two sets of sliding rods are symmetrically arranged, and the sliding rods are slidably connected to the moving block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-precision self-conductive non-standard tooling uses a first drive motor to drive a bidirectional screw to rotate. Utilizing the linkage structure of the slider and support rod, it can synchronously drive the two extrusion plates on both sides to move towards the workpiece and apply clamping force. The rubber pads can increase friction to prevent workpiece slippage and avoid surface damage caused by rigid clamping. The design of the extrusion spring and guide rod can adaptively compensate for the clamping requirements of workpieces of different thicknesses, ensuring reliable fixation and no stress deformation. This solves the problems of cumbersome fixation and insufficient stability of traditional tooling, achieving efficient and stable fixation of the workpiece.

[0016] 2. The meshing structure of the driving bevel gear and the driven bevel gear can realize the synchronous rotation of two sets of bidirectional screws, ensuring that the clamping force of the extrusion plates on both sides is uniform and consistent, avoiding workpiece offset or tilting caused by uneven force on one side, and improving clamping accuracy. At the same time, the transmission structure adopts a fully mechanical rigid connection, which has high power transmission efficiency and rapid response, realizing self-transmission power synchronous control to meet the needs of high-precision machining.

[0017] 3. The second drive motor drives the adjusting screw to rotate. Through the cooperation of the moving block and the slide bar, the fixed seat can be precisely controlled to move linearly in the moving slot of the worktable, realizing the automatic adjustment of the workpiece position. The design of the inverted U-shaped moving block and the double slide bar ensures that the movement process is smooth and without shaking, meeting the flexible adjustment requirements of different cutting processes for the workpiece position, and improving the applicability of the tooling and production efficiency.

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: A high-precision self-conductive non-standard tooling includes a worktable 1 and a mounting block. A fixed seat 2 is slidably mounted on the outer wall of the worktable 1. The outer wall of the fixed seat 2 is provided with a fixing mechanism for fixing the workpiece. The fixing mechanism includes a fixing block 201 fixedly mounted on the outer wall of the fixed seat 2, and a first drive motor 304 is fixedly mounted on the outer wall of the fixing block 201. A bidirectional screw 3 is fixedly mounted on the output end of the first drive motor 304, and a slider 301 is threadedly mounted on the outer wall of the bidirectional screw 3. A support rod 302 is rotatably mounted on the outer wall of the slider 301. A pressing plate 4 slidably mounted on the outer wall of the fixing block 201 and rotatably connected to the end of the support rod 302 is rotatably connected to the end of the bidirectional screw 3. A driving bevel gear 303 is fixedly mounted on the end of the bidirectional screw 3. A transmission shaft 6 is rotatably mounted on the outer wall of the mounting block, and a driven bevel gear 601 is fixedly mounted on the end of the transmission shaft 6. The fixed seat 2 has a rectangular cross-section. 1. The fixed blocks 201 are evenly distributed on the top outer wall of the fixed base 2, and the distance between the two sets of fixed blocks 201 is greater than the width of the workpiece. The length of the bidirectional screw 3 is greater than the distance between the two sets of fixed blocks 201, and two sets of bidirectional screw 3 are symmetrically arranged. The slider 301 is symmetrically arranged on the outer wall of the bidirectional screw 3. The extrusion plate 4 is located between the two sets of fixed blocks 201, and the outer wall of the fixed block 201 is provided with a groove corresponding to the extrusion plate 4. The bottom outer wall of the extrusion plate 4 is provided with pads 401 at equal intervals, and the pads 401 are made of rubber. The outer wall of the pads 401 is in contact with the outer wall of the workpiece. The inner wall of the fixed block 201 is fixedly installed with a guide rod 5 that is slidably connected to the extrusion plate 4, and the outer wall of the guide rod 5 is sleeved with a compression spring 501. The drive shaft 6 is located between the two sets of bidirectional screw 3, and the driven bevel gear 601 is symmetrically arranged on the outer wall of the drive shaft 6, and the driven bevel gear 601 is meshed with the driving bevel gear 303.

[0027] When it is necessary to fix the workpiece, the first drive motor 304 is started, and its output shaft drives the bidirectional screw 3 to rotate. The threaded slider 301 moves axially towards each other when the screw rotates. The slider 301 is rotatably connected to the extrusion plate 4 through the support rod 302. The movement of the slider 301 is converted into a pushing force on the extrusion plate 4 through the support rod 302, so that the two extrusion plates 4 move synchronously towards the workpiece along the groove on the outer wall of the fixing block 201. At this time, the rubber pad 401 at the bottom of the extrusion plate 4 is in contact with the outer wall of the workpiece. The elastic material of the pad 401 increases the friction to prevent the workpiece from sliding, and also adaptively compensates for the difference in workpiece thickness through the compression deformation of the extrusion spring 501. The guide rod 5 restricts the movement direction of the extrusion plate 4 to ensure that the clamping force is applied vertically and evenly to the workpiece. At the same time, the active bevel gear 303 at the end of the bidirectional screw 3 drives the driven bevel gear 601 on the transmission shaft 6 to rotate, so that the two sets of bidirectional screws 3 rotate synchronously, ensuring that the clamping force of the two extrusion plates 4 is completely consistent, avoiding the workpiece from shifting due to uneven force, and realizing high-precision and stable automated clamping.

[0028] Example 2: Based on Example 1, a moving mechanism is also disclosed, the specific structure of which is as follows: The workbench 1 is provided with a moving mechanism for adjusting the position of the fixed seat 2. The moving mechanism includes a moving block 202 fixedly installed at the bottom of the fixed seat 2. A second drive motor 7 is fixedly installed at the end of the workbench 1, and an adjusting screw 701 is fixedly installed at the output end of the drive motor. A moving groove 101 is opened on the outer wall of the workbench 1, and a sliding rod 702 is fixedly installed on the inner wall of the moving groove 101. The moving block 202 has an inverted U-shaped cross section, and the moving groove 101 is correspondingly set with the moving block 202. The length of the moving groove 101 is correspondingly set with the moving range of the moving block 202. The length of the adjusting screw 701 is correspondingly set with the length of the moving groove 101, and the outer wall of the adjusting screw 701 is threadedly connected to the moving block 202. Two sets of sliding rods 702 are symmetrically arranged, and the sliding rods 702 are slidably connected with the moving block 202.

[0029] When the workpiece position needs to be adjusted, the second drive motor 7 is started, and its output shaft drives the adjusting screw 701 to rotate. When the adjusting screw 701 rotates, the moving block 202 moves along the screw axis. At the same time, the sliding rods 702 on both sides guide and support the moving block 202, ensuring that the movement is smooth and without shaking. By controlling the rotation direction and number of rotations of the second drive motor 7, the position of the fixed seat 2 on the worktable 1 can be precisely adjusted, thereby realizing the precise movement of the workpiece in the machining direction, meeting the positioning requirements of different cutting processes, and with the high-precision clamping of the fixing mechanism, the tooling can flexibly and accurately adjust the position of the workpiece.
