Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a multi-directional adjustable tooling fixture assembly for machining parts. Background Technology

[0002] In the field of machining, workpieces need to be processed, including cutting, milling, drilling, and grinding. Fixtures are needed to hold and fix the workpieces to meet the positioning and clamping requirements of complex parts during the machining process and to adapt to diverse machining scenarios. However, traditional tooling fixtures have simple structures and obvious limitations, which reduce the scope of application of the fixtures. Now there is a need for a tooling fixture assembly for parts machining that can be adjusted in multiple directions.

[0003] Based on this, a tooling fixture for automotive parts and its usage method are disclosed through patent search application number CN202210458475.X; by using the pressure block on the left side and the positioning plate on the right side, as well as the first positioning hole and the second positioning hole thereon, the tooling fixture can be adapted to automotive parts of various sizes and styles, and achieves stable clamping of automotive parts. The aforementioned patented device has the following shortcomings when in use: traditional tooling fixtures for parts processing have a simple structure and do not have the function of adjusting the position of the workpiece. Consequently, the fixture assembly cannot be used with processing equipment, reducing the flexibility of the device.

[0004] To address the aforementioned issues, a multi-directional adjustable tooling fixture assembly for parts processing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-directional adjustable tooling fixture assembly for parts processing. By using this device, the problem of traditional tooling fixture assemblies for parts processing in the background art being simple in structure and lacking the function of adjusting the position of the workpiece is solved. Consequently, the fixture assembly cannot be matched with the processing equipment, reducing the flexibility of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional adjustable tooling fixture assembly for machining parts, comprising a base, a clamping assembly on the top surface of the base, a counterweight block fixedly connected to the bottom of the base, and four sets of the counterweight block; a knob rotatably connected to the outer side of the base, a limit groove provided on the top surface of the base, and a turntable rotatably connected to the upper end of the base; the clamping assembly includes a support block fixedly connected to the top surface of the turntable, a hydraulic cylinder fixedly connected to the rear side of the support block, a movable plate slidably connected to the front side of the support block, the movable plate being fixedly connected to the output end of the hydraulic cylinder, a fixed plate fixedly connected to one side of the support block, two sets of the fixed plate, a limit rod fixedly connected between the two sets of the fixed plates, and a worktable fixedly connected to one side of the support block.

[0007] The above-mentioned structural design, by setting four sets of counterweights at the bottom of the base, can effectively lower the center of gravity of the device, enhance the overall stability, and avoid positional shifts caused by vibration during processing; the cooperation between the knob and the turntable provides basic support for subsequent adjustment functions, and the rotation of the turntable can drive the upper clamping components to achieve angle adjustment.

[0008] Preferably, a first threaded rod is rotatably connected inside the base, one end of the first threaded rod is fixedly connected to one side of the knob, and a movable block is threadedly connected to the outer circumference of the first threaded rod, the movable block being slidably connected to one side of the limiting groove.

[0009] With the above-mentioned structure, when the knob rotates, it drives the first threaded rod to rotate synchronously. Utilizing the thread transmission principle, the threaded moving block slides along the limiting groove, realizing the lateral position adjustment of the clamping component. This ensures that the movement process is stable and the accuracy is controllable. The limiting groove constrains the sliding direction of the moving block to avoid deviation, making the lateral adjustment more precise and meeting the needs of different processing positions.

[0010] Preferably, a protective box is fixedly connected to the top surface of the movable block, a heat dissipation hole group is provided on one side of the protective box, and a reduction motor is fixedly connected inside the protective box.

[0011] With the above-mentioned structural design, the protective box can provide physical protection for the internal geared motor, preventing damage to the motor from debris, oil stains, etc. generated during processing; the heat dissipation holes on the side can dissipate the heat generated by the generator in time, extending the service life of the motor; the geared motor provides power for the rotation of the turntable, and its output speed is more suitable for the smooth rotation of the clamping components after being reduced, ensuring the controllability of angle adjustment.

[0012] Preferably, a connecting rod is fixedly connected to the bottom of the turntable, and the connecting rod is fixedly connected to the output end of the geared motor.

[0013] With the above-mentioned structure, the connecting rod transmits the output torque of the geared motor to the turntable, so that the rotational motion of the motor is directly converted into the rotation of the turntable, thereby driving the clamping components above and the workpiece to achieve 360-degree horizontal rotation.

[0014] Preferably, the limiting rod is slidably connected to a sliding block on its outer periphery, and two sets of sliding blocks are provided. A rotating plate component is provided between the moving plate and the sliding block, and two sets of rotating plate components are provided. One end of each set of rotating plate components is rotatably connected to the moving plate, and the other end of each set of rotating plate components is rotatably connected to the two sets of sliding blocks respectively.

[0015] With the above-mentioned structure, the sliding of the two sets of sliding blocks on the limit rod is controlled by the linkage of the rotating plate component. When the hydraulic cylinder drives the moving plate to slide back and forth, the rotating plate component changes the angle by rotating, causing the two sets of sliding blocks to move closer or further away from the limit rod synchronously. The opening and closing of the clamping blocks can be achieved by controlling the hydraulic cylinder. Moreover, the limit rod ensures the linearity of the movement of the sliding blocks, improves the clamping accuracy, and adapts to the fixing requirements of workpieces of different sizes.

[0016] Preferably, each of the two sets of sliding blocks has a groove on one side, a protrusion is slidably connected to one side of the groove, and a clamping block is fixedly connected to one side of the protrusion.

[0017] The design of the above structure provides guidance for the disassembly and installation of the clamping block through the sliding fit of the groove and the protrusion, making the clamping block replacement process smoother; the second threaded rod fixes the sliding block and the protrusion at the same time through the threaded connection, ensuring that the clamping block is stable and does not loosen during operation.

[0018] Preferably, a second threaded rod is threadedly connected to one side of the sliding block, and the protrusion is threadedly connected to the second threaded rod.

[0019] The design of the above structure allows users to replace different types of clamps according to the shape and size of the workpiece, which enhances the versatility of the device and reduces the difficulty of adapting to the processing of special workpieces.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application discloses a multi-directional adjustable tooling fixture assembly for parts processing. The linkage between the base adjustment assembly and the clamping adjustment assembly enables the device to have the ability to adjust horizontal rotation, lateral displacement, and clamping distance, so that the fixture assembly can better cooperate with the processing equipment, improve the applicability of the fixture assembly, and meet the needs of more customers.

[0021] 2. The device's clamping blocks are easy for users to disassemble and install, making it convenient for operators to change clamping blocks of different sizes. The device ensures freedom of movement through motors, hydraulic cylinders, and multiple sets of sliding and rotating connections, ultimately achieving the functional goals of adjustable angle, variable clamping range, and adaptability to various parts. It solves the problems of traditional clamps having single adjustment and poor adaptability, and is suitable for multi-process processing scenarios of complex parts. Attached Figure Description

A knob 11 is rotatably connected to the outer side of the base 1, a limit groove 12 is provided on the top surface of the base 1, and a turntable 14 is rotatably connected to the upper end of the base 1. The clamping assembly 2 includes a support block 21 fixedly connected to the top surface of the turntable 14, a hydraulic cylinder 22 fixedly connected to the rear side of the support block 21, a movable plate 23 slidably connected to the front side of the support block 21, the movable plate 23 being fixedly connected to the output end of the hydraulic cylinder 22, a fixed plate 26 fixedly connected to one side of the support block 21, two sets of fixed plates 26, a limit rod 261 fixedly connected between the two sets of fixed plates 26, and a worktable 211 fixedly connected to one side of the support block 21.

[0027] The present invention will be further described below with reference to the embodiments. Example

[0028] Combination Figures 1-5 The base 1 has a first threaded rod 16 rotatably connected inside. One end of the first threaded rod 16 is fixedly connected to one side of the rotating knob 11. The outer circumference of the first threaded rod 16 is threaded with a moving block 15, which is slidably connected to one side of the limiting groove 12.

[0029] A protective box 17 is fixedly connected to the top surface of the movable block 15. A heat dissipation hole group is provided on one side of the protective box 17. A geared motor 18 is fixedly connected inside the protective box 17.

[0030] A connecting rod 19 is fixedly connected to the bottom of the turntable 14, and the connecting rod 19 is fixedly connected to the output end of the geared motor 18.

[0031] The limiting rod 261 is slidably connected to a sliding block 24 on its outer periphery. There are two sets of sliding blocks 24. A rotating plate component 25 is provided between the moving plate 23 and the sliding block 24. There are two sets of rotating plate components 25. One end of each set of rotating plate components 25 is rotatably connected to the moving plate 23, and the other end of each set of rotating plate components 25 is rotatably connected to the two sets of sliding blocks 24 respectively.

[0032] Both sets of sliding blocks 24 have a groove 243 on one side, a protrusion 242 is slidably connected to one side of the groove 243, and a clamping block 241 is fixedly connected to one side of the protrusion 242.

[0033] The sliding block 24 has a second threaded rod 244 threadedly connected to one side, and the protrusion 242 is threadedly connected to the second threaded rod 244.

[0034] In summary: When using the device, the base 1 is installed on one side of the processing equipment. The four sets of counterweights 13 at the bottom of the base 1 lower the center of gravity, ensuring the overall stability of the device and preventing shaking that could affect processing accuracy. The workpiece is placed on the top surface of the worktable 211. To fix the workpiece, the hydraulic cylinder 22 is activated and controlled to retract, causing the moving plate 23 to slide horizontally away from the workpiece. At the same time, the two sets of rotating plate components 25 rotate. The moving plate 23 is connected to the sliding block 24 through the two sets of rotating plate components 25. When the moving plate 23 moves away from the workpiece, the two sets of rotating plate components 25 drive the two sets of sliding blocks 24 to move closer to each other along the limit rod 261 until the two sets of clamping blocks 241 clamp and fix them on both sides of the workpiece, thus stabilizing the workpiece on the worktable 211. The hydraulic cylinder 22 is then deactivated, allowing the processing equipment to process the stabilized workpiece and preventing the workpiece from shifting position. When the workpiece position needs to be adjusted, the user can rotate the knob 11 on the outside of the base 1. At this time, the first threaded rod 16 rotates synchronously. By rotating the first threaded rod 16 in the forward or reverse direction, the moving block 15 is driven to move horizontally to the left or right. In turn, the moving block 15 will drive the protective box 17, the turntable 14 and the clamping assembly 2 to move, so that the user can easily adjust the left and right lateral position of the workpiece. The protective box 17 at the top of the moving block 15 has a built-in geared motor 18. When the geared motor 18 is started, it can drive the connecting rod 19 to rotate clockwise or counterclockwise. In turn, the connecting rod 19 drives the turntable 14, the clamping assembly 2 and the workpiece to rotate and adjust, so that the clamping assembly 2 and the workpiece can achieve 360-degree horizontal angle adjustment. The user can adjust the position of the workpiece according to the actual processing needs. When it is necessary to remove the workpiece from the clamping assembly 2, the hydraulic cylinder 22 is extended, and the moving plate 23 slides horizontally towards the workpiece. Then, the two sets of rotating plate components 25 drive the two sets of sliding blocks 24 to move away from each other along the limit rod 261. Then, the two sets of clamping blocks 241 move away from each other and give up the clamping work, making it convenient for the user to remove the workpiece from the worktable 211. When the clamping block 241 needs to be replaced, rotate the two sets of second threaded rods 244 in the opposite direction. The second threaded rods 244 rotate and move horizontally away from the protrusion 242 until the second threaded rods 244 and the protrusion 242 are completely separated. The user pushes the protrusion 242 horizontally forward along the groove 243 until the protrusion 242 is pulled out of the groove 243. Then the clamping block 241 can be removed from the sliding block 24 for easy maintenance and replacement. Insert and push the protrusion 242 on one side of the new clamping block 241 along the groove 243 so that the protrusion 242 is installed inside the groove 243 and the mounting hole of the protrusion 242 is aligned with the position of the second threaded rod 244. Then rotate the second threaded rod 244 in the forward direction. The second threaded rod 244 moves horizontally towards the protrusion 242 and the second threaded rod 244 and the protrusion 242 are threadedly fixed, so that the clamping block 241 is re-fixed on one side of the sliding block 24.
