[0002] Hardware: Traditional hardware products, also known as "small hardware". It refers to five metals: gold, silver, copper, iron, and tin. Through manual processing, they can be made into artworks such as knives and swords or metal devices. Hardware in modern society is more extensive, such as hardware tools, hardware parts, daily hardware, building hardware, and security supplies, etc. Most small hardware products are not final consumer goods. A fixture refers to a device used in the process of mechanical manufacturing to fix the processing object, make it occupy the correct position, and accept construction or inspection, also known as a jig. Generally speaking, in any process of the technological process, a device used to quickly, conveniently, and safely install the workpiece can be called a fixture. A fixture usually consists of positioning elements (to determine the correct position of the workpiece in the fixture), a clamping device, tool alignment and guiding elements (to determine the relative position between the tool and the workpiece or guide the tool direction), indexing devices (to enable the workpiece to complete the processing of several stations in one installation, including rotary indexing devices and linear moving indexing devices), connecting elements, and a fixture body (the fixture base), etc.

[0003] When the existing hardware processing fixtures clamp some special-shaped hardware parts, such as round and uneven-surface hardware parts, the traditional fixtures fail to clamp the special-shaped hardware parts tightly, resulting in easy shaking during processing and deviation in processing accuracy. For this reason, a hardware processing fixture with special-shaped clamping is proposed. Content of the Utility Model

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1

[0026] As Figures 1-5As shown in the figure, the present utility model provides the following technical solutions to achieve the above purposes: A hardware processing fixture with special-shaped clamping, including: a base 1, a rotating component 2 is arranged on the inner wall of the base 1 for rotating the rotating block 3 to facilitate the processing of different positions of the hardware. The rotating block 3 is fixedly connected to the top of the rotating component 2. The first limiting block 4 is fixedly connected to the top of the base 1 for limiting the rotating block 3. The workbench 5 is fixedly connected to the top of the rotating block 3. A moving component 6 is arranged on the inner wall of the workbench 5 for moving the clamping component 7. The clamping component 7 is arranged on the top of the moving component 6 for clamping the hardware parts.

[0027] The moving component 6 includes a moving groove 61, a motor 62, a bidirectional threaded rod 63, a second limiting block 64, and a threaded sleeve 65. The moving groove 61 is opened on the top of the workbench 5. The motor 62 is fixedly connected to the inner wall of the moving groove 61. The bidirectional threaded rod 63 is fixedly connected to the output end of the motor 62. The second limiting block 64 is fixedly connected to the bottom of the inner wall of the moving groove 61. The bidirectional threaded rod 63 movably penetrates through the second limiting block 64. The threaded sleeve 65 is threadedly connected to the outer wall of the bidirectional threaded rod 63. The number of threaded sleeves 65 is two, symmetrically arranged with respect to the midline of the workbench 5. The threaded sleeve 65 is moved towards the second limiting block 64 by the bidirectional threaded rod 63.

[0028] The clamping component 7 includes a housing 71, a sliding groove 72, a first slider 73, a second slider 74, a limiting hole 75, a limiting post 76, and an auxiliary clamping block 77. The housing 71 is fixedly connected to the top of the threaded sleeve 65. The sliding groove 72 is opened on the inner wall of the housing 71. The sliding groove 72 is U-shaped. The first slider 73 and the second slider 74 are slidably connected to the inner wall of the sliding groove 72. The number of first sliders 73 is two, symmetrically arranged with respect to the middle of the housing 71. The auxiliary clamping block 77 is slidably connected to the inner wall on the right side of the first slider 73. The hardware is clamped by the first slider 73 and the auxiliary clamping block 77.

[0029] The limiting hole 75 is opened in the middle of the first slider 73 and the second slider 74. The limiting post 76 is fixedly connected to the bottom of the inner wall of the sliding groove 72. The number of limiting posts 76 is three and is arranged in the limiting hole 75.

[0030] In this embodiment, by placing the hardware on the workbench 5 and starting the motor 62 to rotate the bidirectional threaded rod 63, the threaded sleeves 65 at both ends of the bidirectional threaded rod 63 move towards the second limit block 64 simultaneously, thus achieving the moving effect. The second limit block 64 plays a limiting role to prevent the clamping assembly 7 from hitting and damaging the fixture. While moving, the first slider 73 will approach the hardware. When the hardware is circular, the first slider 73 will not move backward, causing the second slider 74 to move, and only the auxiliary clamping block 77 will achieve a small offset to adapt to the shape of the circular hardware. When the hardware is an object with an uneven surface, in the case where the front of the hardware is large and the back is small, the first slider 73 on the right side of the chute 72 will move backward, thereby pushing the second slider 74 to move leftward. The leftward movement of the second slider 74 causes the first slider 73 on the left side to move rightward, cooperating with the fine adjustment of the auxiliary clamping block 77, thus achieving the special-shaped clamping function.

[0031] Embodiment 2

[0032] As Figures 1-5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the rotating assembly 2 includes a first bearing 21, a worm 22, a knob 23, a second bearing 24, a rotating rod 25, and a worm gear 26. The outer wall of the first bearing 21 is fixedly connected to the inner wall of the base 1. The worm 22 is inserted into the inner wall of the first bearing 21. The worm 22 movably penetrates the inner wall of the base 1 and extends to the left. The knob 23 is fixedly connected to the extended end of the worm 22. The outer wall of the quick delivery second bearing 24 is fixedly connected to the bottom of the inner wall of the base 1. The rotating rod 25 is inserted into the inner wall of the second bearing 24. The worm gear 26 is fixedly connected to the outer wall of the rotating rod 25. The worm gear 26 is meshed with the worm 22. Self-locking is achieved through the worm 22 and the worm gear 26 to prevent the workbench 5 from rotating during processing.

[0033] One end of the rotating rod 25 away from the second bearing 24 movably penetrates the top of the base 1 and extends upward. The extended end of the rotating rod 25 is fixedly connected to the bottom of the rotating block 3.

[0034] In this embodiment, by rotating the knob 23 to drive the worm 22 to rotate in the first bearing 21, the meshed worm gear 26 is driven to rotate by the worm 22. The worm gear 26 drives the rotating rod 25 to rotate in the second bearing 24. The rotating block 3 is driven to rotate through the rotating rod 25, thereby rotating the workbench 5 and realizing the adjustment of the processing angle during hardware processing.

[0035] Next, specifically describe the working principle of the special-shaped clamping hardware processing fixture.

[0036] As Figures 1-5As shown in the figure, when in use, place the hardware on the workbench 5, start the motor 62 to rotate the bidirectional threaded rod 63. The bidirectional threaded rod 63 makes the threaded sleeves 65 at both ends move towards the second limiting block 64 at the same time, thus achieving the moving effect. The second limiting block 64 plays a limiting role to prevent the clamping assembly 7 from hitting and damaging the fixture. While moving, the first slider 73 will approach the hardware. When the hardware is circular, the first slider 73 will not move backward, causing the second slider 74 to move. Only the auxiliary clamping block 77 realizes a small offset to adapt to the shape of the circular hardware. When the hardware is an object with an uneven surface, in the case of the front of the hardware being large and the back being small, the first slider 73 on the right side of the chute 72 will move backward, thereby pushing the second slider 74 to move leftward. The leftward movement of the second slider 74 causes the first slider 73 on the left side to move rightward, cooperating with the fine adjustment of the auxiliary clamping block 77, thus realizing the special-shaped clamping function. Rotate the knob 23 to drive the worm 22 to rotate in the first bearing 21. The worm 22 drives the engaged worm wheel 26 to rotate. The worm wheel 26 drives the rotating rod 25 to rotate in the second bearing 24. The rotating rod 25 drives the rotating block 3 to rotate, thereby rotating the workbench 5 and realizing the adjustment of the processing angle during the processing of the hardware.
