Description

Technical Field

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

[0002] The requirements for machining precision parts are very strict, including the dimensions and accuracy of the parts. It is also necessary to ensure that the position of the parts does not shift during machining. Therefore, precision machining fixtures are required. Precision machining fixtures are equipped with clamping plates to hold the precision parts. The clamping plates limit the position of the precision parts and prevent them from shifting. The lower end of the clamping plates moves along a slide groove, which limits the direction of movement of the clamping plates and also ensures the stability of the clamping plates during movement.

[0003] Chinese utility model patent CN219747247U discloses a precision parts machining fixture, including a mounting plate and two movable plates located on the left and right sides above it. A clamping plate is connected to the inner side of each movable plate. Slide grooves are formed on both the front and rear of the mounting plate. A moving component is provided between the front slide groove and the mounting plate. The moving component includes a bidirectional lead screw, a motor, a slider, a connecting plate, and a sliding rod. A blocking component is provided on the outer side of the mounting plate to block the slide grooves. A friction pad is connected to the inner side of the clamping plate. The bidirectional lead screw is rotatably connected inside the front slide groove. The motor is mounted on the right side of the mounting plate, and the right end of the bidirectional lead screw passes through the mounting plate and connects to the motor's power output end. This utility model effectively protects the slide grooves, preventing debris from entering the slide grooves during parts machining and affecting the normal operation of the fixture.

[0004] Existing precision parts machining fixtures can only perform simple clamping on the outer surface of the parts. When clamping the parts, operators can only rely on experience and feeling, which can easily lead to excessive clamping force, thereby damaging the outer surface of the parts and affecting their appearance and performance. Therefore, there is a problem that the clamping force cannot be detected. Utility Model Content

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a precision parts processing fixture, including a base 1. A clamping mechanism 2 is slidably connected to the outer surface of the base 1. A replacement mechanism 3 is fixedly connected to the outer surface of the clamping mechanism 2. The clamping mechanism 2 includes a sliding block 207 slidably connected to the outer surface of the base 1. A display controller 201 is fixedly connected to the outer surface of the sliding block 207. A pressure sensor 208 is electrically connected to the outer surface of the display controller 201 through a wire. The outer surface of the pressure sensor 208 is embedded inside the sliding block 207.

[0032] Specifically, a geared motor 203 is fixedly connected to the outer surface of the base 1. The output shaft of the geared motor 203 passes through the inner side of the base 1 and is fixedly connected to a bidirectional threaded rod 206. A connecting block 204 is threadedly connected to the outer surface of the bidirectional threaded rod 206. The outer surface of the connecting block 204 is fixedly connected to the outer surface of the sliding block 207. A limit rod 205 is slidably connected to the outer surface of the sliding block 207. One end of the limit rod 205 is fixedly connected to a limit ring 202, and the other end of the limit rod 205 is fixedly connected to the outer surface of the mounting block 302.

[0033] The geared motor 203 is further activated, and the output shaft of the geared motor 203 drives the bidirectional threaded rod 206 to rotate. The rotation of the bidirectional threaded rod 206 causes the connecting block 204 to slide on the inner wall of the base 1. The sliding of the connecting block 204 causes the two sets of sliding blocks 207 to move in opposite directions, which facilitates the clamping of the parts. The pressure sensor 208 facilitates the detection of the clamping force of the parts. At the same time, the pressure on the outer surface of the parts is displayed on the outer surface of the display controller 201, which facilitates the control of the force on the outer surface of the parts and avoids damage to the outer surface of the parts.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The replacement mechanism 3 includes a mounting base 305 fixedly connected to the detection end of the pressure sensor 208. A mounting block 302 is slidably connected to the inner side of the mounting base 305. A clamping plate 301 is fixedly connected to the outer surface of the mounting block 302.

[0036] Specifically, the outer surface of the mounting base 305 is fixedly connected to a fixed frame 303, the outer surface of the fixed frame 303 is slidably connected to a sliding rod 308, one end of the sliding rod 308 is fixedly connected to a locking block 306, the outer surface of the locking block 306 is fixedly connected to a spring 309, the other end of the spring 309 is fixedly connected to the inner wall of the fixed frame 303, the end of the sliding rod 308 away from the locking block 306 is fixedly connected to a pull ring 304, the outer surface of the pull ring 304 is in contact with the outer surface of the fixed frame 303, the outer surface of the mounting block 302 is provided with a slot 307, and the locking block 306 is slidably connected to the outer surface of the slot 307.

[0037] Pulling the pull ring 304 further causes the sliding rod 308 and the locking block 306 to slide on the inner wall of the mounting base 305, which facilitates the disassembly of the clamping plate 301. Releasing the pull ring 304 facilitates the reset of the locking block 306 and the sliding rod 308. Then, the mounting block 302, which is fixed to the outer surface of another set of clamping plates 301, is inserted into the inner side of the mounting base 305. The outer surface of the mounting block 302 presses against the outer surface of the locking block 306. When the locking groove 307 moves to the locking block 306, the spring 309 rebounds, causing the locking block 306 to slide into the locking groove 307, which facilitates the limiting of the mounting block 302 and, to a certain extent, facilitates the replacement of clamping plates 301 of different models.

[0038] Working principle: By pulling the pull ring 304, the pull ring 304 drives the sliding rod 308 and the locking block 306 to slide on the inner wall of the mounting base 305, compressing the spring 309. At the same time, the locking block 306 slides out of the slot 307, and then the clamping plate 301 and the mounting block 302 slide upward, which facilitates the disassembly of the clamping plate 301. Releasing the pull ring 304 facilitates the reset of the locking block 306 and the sliding rod 308. Then, the mounting block 302, which is fixed to the outer surface of another set of clamping plates 301, is inserted into the inner side of the mounting base 305. The outer surface of the mounting block 302 presses against the outer surface of the locking block 306, causing the locking block 306 to slide on the inner wall of the mounting base 305. When the slot 307 moves to the locking block 306, The spring 309 rebounds, causing the locking block 306 to slide into the locking groove 307, thus facilitating the limiting of the mounting block 302. By starting the reduction motor 203, the output shaft of the reduction motor 203 drives the bidirectional threaded rod 206 to rotate. The rotation of the bidirectional threaded rod 206 causes the connecting block 204 to slide on the inner wall of the base 1. The sliding of the connecting block 204 causes the two sets of sliding blocks 207 to move in opposite directions, thus facilitating the clamping of the parts. The pressure sensor 208 facilitates the detection of the clamping force of the parts. At the same time, the pressure on the outer surface of the parts is displayed on the outer surface of the display controller 201, thus facilitating the control of the force on the outer surface of the parts and avoiding damage to the outer surface of the parts.
