[0027] In Embodiment 1 of the present utility model:

[0028] As Figures 1 - 5 shown, a fixture for facilitating the replacement of fasteners is provided, including: a mounting table 1, which serves as the main body of the fixture for placing workpieces; a clamping block 2, which is arranged on the top of the mounting table 1 for clamping workpieces, and a flexible clamping block 302 is arranged on one side of the clamping block 2 for improving the clamping stability; a clamping assembly, which is arranged on the top of the mounting table 1 for driving the clamping block 2 to quickly clamp and fix workpieces; a mounting assembly, which is arranged on one side of the clamping block 2 for quickly repairing and replacing the clamping assembly; an inflation assembly, which is arranged inside the clamping block 2 for inflating the flexible clamping block 302 to improve the clamping fit.

[0029] During the use process, the mounting table 1 is used as the basic support component of the entire fixture to carry and position workpieces. At the same time, in the clamping assembly, it is slidably connected to the movable groove 101 on the mounting table 1 through its bottom, and the driving shaft 103 driven by the driving motor 102 is used to achieve movement, so as to clamp or release the workpiece, thereby providing a stable and reliable workpiece fixing platform. During the clamping process, it can deform according to the shape of the workpiece, and the inflation assembly inflates its interior to increase the pressure on the contact surface with the workpiece, improving the clamping stability.

[0030] Furthermore, the clamping assembly includes: a plurality of movable grooves 101 opened on the top of the mounting table 1, and the clamping block 2 is slidably connected to the movable grooves 101; a driving motor 102 arranged on the inner wall of the movable groove 101, a driving shaft 103 is arranged on one side of the driving motor 102, and the driving shaft 103 is threadedly engaged with the clamping block 2.

[0031] During use, the drive motor 102 is threadedly engaged with the clamping block 2 through the drive shaft 103. When the motor starts, the drive shaft 103 rotates to push the clamping block 2 to move linearly along the movable groove 101. The cooperation of the drive motor 102 and the drive shaft 103 provides precise control, making the clamping action faster and more accurate. The laterally moving clamping blocks 2 cooperate with each other to quickly clamp the workpiece.

[0032] Furthermore, a limiting rod 104 is provided inside the movable groove 101, and a limiting groove 201 is opened inside the clamping block 2. The clamping block 2 is slidably connected to the limiting rod 104 through the limiting groove 201. During use, the sliding connection between the limiting rod 104 and the clamping block 2 ensures the linear movement of the clamping block 2. The limiting rod 104 ensures the linearity of the clamping block 2 during movement, improving the stability and precision of clamping.

[0033] Furthermore, a circuit board 4 is provided on one side of the bottom of the mounting table 1. Two wiring ports 401 are opened on one side of the circuit board 4. During use, the drive motor 102 and the blower 204 are controlled through the circuit board 4, and the wiring ports 401 can be connected to an external power source and connected to the host of the processing equipment to achieve the control effect.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, the mounting assembly includes: a mounting opening 202 opened on one side of the clamping block 2; a fastener 3 provided on one side of the flexible clamping block 302. An installation plate 301 is provided on one side of the fastener 3, and the installation plate 301 is slidably connected to the mounting opening 202. During use, the fastener 3 is slidably connected to the mounting opening 202 through the installation plate 301, which is convenient for replacement. When the fastener 3 needs to be replaced, only the installation plate 301 needs to be slid out of the mounting opening 202 to complete the disassembly. In this way, the fastener 3 and the flexible clamping block 302 can be quickly replaced. During use, it is convenient for the user to disassemble and maintain the device, simplifies the maintenance process of the device, and improves the maintenance efficiency of the device.

[0036] Embodiment 3

[0037] Based on Embodiment 1, the inflation assembly includes: an air inlet pipe 203 opened on one side of the clamping block 2, and a blower 204 is provided inside the air inlet pipe 203; an air charging pipe 304 provided on one side of the flexible clamping block 302. The inside of the flexible clamping block 302 is provided with a hollow structure, and the air inlet pipe 203 is respectively communicated with the air charging pipe 304 and the inside of the flexible clamping block 302. During use, the blower 204 inflates the inside of the flexible clamping block 302 through the air inlet pipe 203. The clamping force of the flexible clamping block 302 is increased by the effect of inflation, ensuring that the workpiece is firmly clamped.

[0038] Further, a filter screen 205 is provided inside the air inlet pipe 203. The filter screen 205 is a 1200-mesh high-density metal filter screen. During use, the filter screen 205 prevents impurities from entering the inflation system, ensuring the cleanliness of the inflation process, thereby preventing the situation where dust accumulates in the inflation pipeline and causes damage and difficulty in use.

[0039] Further, arc-shaped telescopic strips 303 are provided on both sides of the flexible clamping block 302, and the inside of the telescopic strip 303 is communicated with the inside of the flexible clamping block 302. During use, when the flexible clamping block 302 is inflated, the telescopic strips 303 on both sides will expand and extend when filled with gas. The telescopic strips 303 are used to fit the surface of the workpiece by the effect of expansion and extension, and at the same time improve the contact surface and friction force during fitting, so that the workpiece can be better fixed.

[0040] Further, an insertion pipe 207 is provided at the end of the guiding pipe 206. The insertion pipe 207 is located at the bottom of the installation port 202. The opening of the air charging pipe 304 is provided at the bottom of the installation plate 301, and the insertion pipe 207 is inserted and connected with the air charging pipe 304. The insertion pipe 207 and the air charging pipe 304 are used to introduce gas from the air inlet pipe 203 into the inside of the flexible clamping block 302, so that the flexible clamping block 302 expands. During this process, the insertion pipe 207 ensures that the installation plate 301 and the installation port 202 can be disassembled and separated, while enabling the device to maintain the effect of expanding and clamping and fixing after installation.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
