Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a fixture for precision machining of parts. Background Technology

[0002] During the precision machining of parts, the cutting, grinding, stamping, and drilling processes must strictly meet the design requirements. Therefore, it is necessary to use fixtures to fix the mechanical parts and ensure that they are in a stable state during machining to avoid deviation of the parts and cause deviation of the machining area.

[0003] In existing technical solutions, the clamping components and drive units of machining fixtures are usually integrated. When clamping parts for a long time, the surface of the clamping components is prone to wear or even deformation. Therefore, the clamping components need to be replaced periodically. However, the operators cannot replace the clamping components individually, but can only replace the entire machining fixture, which increases the replacement cost of the machining fixture. Utility Model Content

[0004] This application provides a precision machining fixture for parts, which solves the technical problem that in the prior art, the clamping component and the driving unit of the machining fixture are usually an integral structure. When the clamping component clamps the parts for a long time, the surface of the clamping component is prone to wear or even deformation. Therefore, the clamping component needs to be replaced from time to time. However, the operator cannot replace the clamping component alone, but can only replace the entire machining fixture, which leads to an increase in the replacement cost of the machining fixture.

[0005] The technical solution adopted in the embodiments of this application is as follows:

[0006] A precision machining fixture for parts includes a base, a clamping member for clamping parts, a support groove for supporting the clamping member, a fixing member for fixing the clamping member, and a driving device for driving the support groove to move. Two sets of the driving devices are symmetrically arranged on the top of the base. The driving ends of both sets of driving devices are provided with the support groove. The clamping member is slidably installed on both sets of support grooves. The two sets of clamping members are respectively fixed to the corresponding support grooves by the fixing member. A limit plate is provided at one end of the support groove.

[0007] A further technical solution is as follows: the clamping component includes an "I"-shaped slider, a clamping plate for abutting against the component, and a buffer for cushioning the clamping plate; the "I"-shaped slider is slidably mounted on the support groove; a number of buffers arranged in a linear array are provided between the clamping plate and the "I"-shaped slider; a bent handle is provided at one end of the "I"-shaped slider.

[0008] A further technical solution is as follows: the buffer includes a limiting groove, a guide block sliding in the limiting groove, a spring for buffering the guide block, and a telescopic rod for limiting the spring; the limiting groove is disposed on the "I"-shaped slider; the guide block is disposed on the clamping plate; the spring is disposed around the telescopic rod; the telescopic end of the telescopic rod is connected to the guide block; and the other end of the telescopic rod is connected to the limiting groove.

[0009] A further technical solution is as follows: the clamping member further includes a damping pad; the clamping plate is provided with a number of damping pads arranged in a linear array.

[0010] A further technical solution is that a crosshair is provided at the center of the top of the base.

[0011] A further technical solution is that the driving device is a cylinder.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. By employing a base, clamping components, support grooves, fixing components, and a drive unit, the clamping components are separated from the drive unit, and the fixing components can be individually disassembled and replaced, avoiding the need to replace the entire fixture and saving costs. The springs and telescopic rods in the buffer provide flexible clamping, reducing rigid impact between the clamping plate and the parts, and lowering the risk of wear and deformation. Damping pads increase clamping friction, preventing parts from shifting during machining. The crosshairs on the top of the base assist in quick alignment, improving machining accuracy. The bent handle design facilitates manual operation for assembling and disassembling the clamping components. The drive unit provides stable driving force, fast response, and simple maintenance. The sliding cooperation between the support groove and the "I"-shaped slider supports flexible adaptation to clamping components of different sizes, expanding the application scenarios of the fixture. This utility model, through detachable clamping components, an elastic buffer structure, and a precise positioning design, solves the problems of high replacement costs and easy wear of traditional fixtures, while improving clamping stability and operational efficiency.

[0018] This application provides a precision machining fixture for parts, which solves the technical problem that in the prior art, the clamping component and the driving unit of the machining fixture are usually an integral structure. When the clamping component clamps the parts for a long time, the surface of the clamping component is prone to wear or even deformation. Therefore, the clamping component needs to be replaced from time to time. However, the operator cannot replace the clamping component alone, but can only replace the entire machining fixture, which leads to an increase in the replacement cost of the machining fixture.

[0019] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] The clamping component 2 includes an "I"-shaped slider 21, a clamping plate 22 for abutting against the components, and a buffer component 23 for buffering the clamping plate 22. The "I"-shaped slider 21 is slidably mounted on the support groove 3. Several sets of buffer components 23 arranged in a linear array are provided between the clamping plate 22 and the "I"-shaped slider 21. A bent handle 211 is provided at one end of the "I"-shaped slider 21.

[0024] Several sets of buffer components 23 arranged in a straight line are fixedly connected between the clamping plate 22 and the "I"-shaped slider 21. A bent handle 211 is fixedly connected to one end of the "I"-shaped slider 21.

[0025] The buffer component 23 includes a limiting groove 231, a guide block 232 sliding in the limiting groove 231, a spring 233 for buffering the guide block 232, and a telescopic rod 234 for limiting the spring 233. The limiting groove 231 is provided on the "I"-shaped slider 21. The guide block 232 is provided on the clamping plate 22. The spring 233 is arranged around the telescopic rod 234. The telescopic end of the telescopic rod 234 is connected to the guide block 232. The other end of the telescopic rod 234 is connected to the limiting groove 231.

One end of the spring 233 is fixedly connected to the guide block 232. The other end of the spring 233 is fixedly connected to the limiting groove 231.

[0027] The clamping member 2 also includes damping pads 24. Several sets of damping pads 24 are arranged in a linear array on the clamping plate 22.

[0028] Several sets of damping pads 24 arranged in a straight line are fixedly connected to the clamping plate 22.

[0029] A crosshair is provided at the center of the top of the base 1.

[0030] Two sets of drive devices 5 (cylinders) are symmetrically installed on the top of the base 1. The drive end of the drive device 5 (cylinder) is connected to the support groove 3. The clamping component 2 is slidably installed in the support groove 3 and is fixed to the support groove 3 by the fixing component 4 (screw). One end of the support groove 3 is provided with a limiting plate 31 to prevent the clamping component 2 from slipping off. The clamping component 2 consists of an "I"-shaped slider 21, a clamping plate 22, a buffer component 23, and a damping pad 24.

[0031] Workflow: Place the component at the top center of base 1 and calibrate its position using crosshairs. Activate drive device 5 (cylinder), which moves the two side support slots 3 towards the center. Clamping member 2 elastically clamps the component via buffer member 23, and damping pad 24 prevents the component from sliding. After processing, drive device 5 (cylinder) resets and releases clamping member 2, allowing the component to be removed. If clamping member 2 is worn, loosen fixing member 4, slide clamping member 2 out via bending handle 211, replace with a new one, and re-fix.

[0032] By employing a base 1, clamping component 2, support groove 3, fixing component 4, and drive device 5, the clamping component 2 can be separated from the drive device 5, and the fixing component 4 can be disassembled and replaced individually, avoiding the need to replace the entire fixture and saving costs. The spring 233 and telescopic rod 234 in the buffer component 23 provide flexible clamping, reducing rigid impact between the clamping plate 22 and the parts, and lowering the risk of wear and deformation. The damping pad 24 increases clamping friction, preventing parts from shifting during processing. The crosshair on the top of the base 1 assists in quick alignment, improving processing accuracy. The bent handle 211 is designed for easy manual operation of the clamping component 2 for assembly and disassembly. The drive device 5 provides stable driving force, fast response, and simple maintenance. The sliding cooperation between the support groove 3 and the "I"-shaped slider 21 supports flexible adaptation of clamping components 2 of different sizes, expanding the application scenarios of the fixture. This utility model, through the detachable clamping component 2, elastic buffer structure, and precise positioning design, solves the problems of high replacement cost and easy wear of traditional fixtures, while improving clamping stability and operating efficiency.
