Description

Technical Field

[0001] This utility model belongs to the field of precision hardware processing technology, specifically relating to an automatic sandblasting fixture for precision hardware surfaces. Background Technology

[0002] Precision hardware products typically employ advanced processing technologies, such as CNC machining, wire cutting, laser cutting, stamping, forming, and casting, to ensure high precision and high quality manufacturing. During the manufacturing and processing process, some dirt, grease, oxides, and other impurities may adhere to the surface of precision hardware. Sandblasting can effectively remove these impurities, making the surface of the hardware parts cleaner. During sandblasting, the hardware parts need to be clamped and fixed.

[0003] Existing precision metal fixtures are generally suitable for small to medium-sized workpieces and cannot hold excessively large workpieces. In addition, some fixtures can only hold round or regular-shaped workpieces and are not suitable for irregularly shaped workpieces. Furthermore, the clamping force of most precision metal fixtures may be insufficient, especially when dealing with products with complex structures. For example, when vacuum fixtures need to avoid the concave and convex structures of the product, insufficient suction may result in tool marks or tool lines. To address this issue, we propose an automatic sandblasting fixture for precision metal surfaces. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic sandblasting fixture for precision hardware surfaces to solve the problems mentioned in the background art.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an automatic sandblasting fixture for precision hardware surfaces, including a base 1, a mounting hole 2 penetrating through the center of the surface of the base 1, a turntable 3 rotatably connected to the inner side of the mounting hole 2, a guide hole 4 on the surface of the turntable 3, four sets of guide holes 4 arranged in a ring around the center of the turntable 3, track plates 5 respectively installed at the four corners of the surface of the base 1, sliders 7 slidably installed on the surface of the track plates 5, clamping blocks 8 fixedly installed at the ends of the sliders 7, a connecting rod 13 slidably installed inside the guide hole 4, a limiting block 14 fixedly installed at the bottom end of the connecting rod 13, the top end of the connecting rod 13 being fixedly connected to the bottom surface of the slider 7, a fixing frame 15 fixedly installed at the bottom of the base 1, a connecting shaft 16 rotatably passing through the surface of the fixing frame 15, the top end of the connecting shaft 16 being fixedly connected to the bottom surface of the turntable 3, a motor 17 fixedly installed at the bottom of the fixing frame 15, and the top output end of the motor 17 being fixedly connected to the bottom end of the connecting shaft 16.

[0020] Specifically, a lifting rod 10 is rotatably connected to the center of the surface of the turntable 3, and a processing table 11 is fixedly connected to the top of the lifting rod 10. The operation of the lifting rod 10 can drive the processing table 11 to rise and fall, so as to adjust the height of the hardware parts as needed.

[0021] Specifically, a first protective pad 9 is provided on one side of the clamping block 8. One side of the first protective pad 9 is fixedly connected to one side surface of the clamping block 8. The first protective pad 9 can prevent the clamping block 8 from causing wear on the surface of the hardware.

[0022] Specifically, a second protective pad 12 is provided above the processing table 11. The bottom of the second protective pad 12 is fixedly connected to the surface of the processing table 11. The second protective pad 12 can protect the bottom of the hardware parts above the processing table 11.

[0023] Specifically, the surface of the track plate 5 is provided with multiple sets of screws 6, and the track plate 5 and the surface of the base 1 are fixedly connected by the screws 6. The screws 6 improve the stability of the track plate 5 and the base 1.

[0024] Specifically, support frames 18 are symmetrically fixedly installed on both ends of the bottom surface of the base 1. Multiple sets of positioning holes 19 are opened through the bottom surface of the support frame 18.

[0025] In this embodiment, precision hardware is placed above the processing table 11. The operation of the motor 17 drives the connecting shaft 16 to rotate. The rotation of the connecting shaft 16 drives the turntable 3 to rotate inside the mounting hole 2. The rotation of the turntable 3 drives the guide hole 4 on the surface to rotate. The rotation of the guide hole 4 drives the slider 7 to move on the surface of the track plate 5 through the connecting rod 13. The movement of the slider 7 drives the clamping block 8 to move towards the surface of the processing table 11, thereby clamping and fixing the hardware above the processing table 11 and improving work efficiency.
