DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 3 In the embodiment of the present utility model, a fixture for hardware production and processing includes a base 1, one end of the top of the base 1 is provided with two parallel first slide grooves 11, and the other end of the base 1 is provided with two symmetrically arranged second slide grooves 12; a movable seat 2 is slidably assembled on the first slide groove 11 along the length direction of the first slide groove 11, one end of the movable seat 2 is fixedly connected to a first clamping plate 21, and both sides of the first clamping plate 21 are provided with guide strips 22 integrally formed with the movable seat 2; a second clamping plate 3 is provided on the opposite side of the first clamping plate 21, and the outer side of the second clamping plate 3 is provided with a fixed seat 31 fixedly connected to the base 1, The upper end of the fixed seat 31 is threadedly connected to the first bolt 32, and the tail end of the first bolt 32 is rotatably connected to the second clamping plate 3; two groups of clamping components 4 are slidably installed on the two second slide grooves 12 respectively, and the two groups of clamping components 4 are located at the two side ends between the first clamping plate 21 and the second clamping plate 3 to adapt to the first clamping plate 21 and the second clamping plate 3 to form a rectangular four-end clamping structure, and the outer ends of the two groups of clamping components 4 are respectively slidably connected to the guide bars 22 at the corresponding positions; a driving member 5 is provided on one side of the movable seat 2 for driving the movable seat 2 to move along the length direction of the first slide groove 11; the driving member 5 is a cylinder or an electric push rod.

[0026] In this embodiment: Since the clamping and fixing devices used in the existing hardware processing are usually double-sided holding structures, but the shapes of the hardware are different, they are prone to slipping during the holding process, and the clamping is not stable enough, and even cause the hardware to fly and injure the workers during the processing. Secondly, the existing hardware processing and fixing devices usually use bolt connections, which is not convenient for the rapid disassembly and assembly of hardware. Therefore, this solution fixes the hardware during processing by setting up a four-sided clamping and fixing method, further improving the stability of the clamping, and at the same time it is more convenient to clamp or loosen the hardware, saving the time spent on clamping or loosening the hardware, and indirectly improving work efficiency; in addition, the clamping spacing of the clamping and fixing structure can be adjusted to meet the clamping and fixing of hardware of different sizes.

[0027] Specifically, the fixing device in this scheme is composed of a clamping structure on four surfaces. When the hardware needs to be fixed, the driving member 5 is first used to push the movable seat 2 to move along the length direction of the first slide groove 11, and gradually approach the second clamping plate 3. At the same time, the movable seat 2 will also drive the two groups of clamping components 4 to slide in their respective second slide grooves 12 during the movement, so that the two groups of clamping components 4 are close to each other. This scheme only uses one driving member 5 to drive the three clamping surfaces to gather toward the center to clamp and fix the hardware. Conversely, the driving member 5 is also used to drive the three clamping surfaces to disperse and release the clamping and fixation of the hardware. The clamping or releasing operation is convenient and quick.

[0028] It should be noted that during the manufacturing process of hardware, hardware of the same size is generally processed in batches. Therefore, after adjusting the clamping spacing of the four surfaces, the hardware can be clamped and fixed solely by the action of the driver 5. If it is necessary to clamp and fix hardware of a different size, the size of the hardware is first measured using a measuring tool, and then the spacing between the four clamping surfaces is adjusted.

[0029] Please refer to Figures 1 to 3 The clamping assembly 4 includes: a slider 401 that is slidably assembled on the second slide groove 12 along the length direction of the second slide groove 12, and a plurality of equally spaced screw holes 405 are opened on the top of the slider 401; a fixed block 402 fixedly connected to one end of the slider 401, the middle part of the fixed block 402 is threadedly connected to a second bolt 404, and the tail end of the second bolt 404 is rotatably connected to the third clamping plate 403; and a limiting stud 406 screwed into one of the screw holes 405, and the limiting stud 406 is located on the inner side of the guide groove 23; the bottom ends of the first clamping plate 21, the second clamping plate 3 and the two third clamping plates 403 are on the same horizontal plane, and the first clamping plate 21, the second clamping plate 3 and the two third clamping plates 403 are arranged at the same height.

[0030] In this embodiment: When it is necessary to clamp and fix hardware of different sizes, first use the driving member to push the movable base 2 to the end position, and then adjust the other three clamping surfaces. Since the first clamping plate 21 is fixedly connected to the movable base 2 and cannot be adjusted, it is only necessary to adjust the spacing between the second clamping plate 3 and the first clamping plate 21. By turning the first bolt 32, the second clamping plate 3 is restricted by the top surface of the base 1 and can only move forward and backward, which can change the spacing between the second clamping plate 3 and the first clamping plate 21. The spacing between the two third clamping plates 403 can be adjusted by the second bolt 404 (the same as the adjustment of the second clamping plate 3), and can also be adjusted by the limit stud 406 on different screw holes 405. After determining the clamping size, the hardware of the same batch size can be quickly clamped and fixed.

[0031] Please refer to Figure 2 A guide groove 23 is provided in the length direction of the guide bar 22 , and the middle portion of the guide groove 23 is an inclined structure; the outer diameter of the upper end of the limiting stud 406 matches the width of the guide groove 23 .

[0032] In this embodiment: the middle inclined structure of the guide groove 23 is used to guide the limiting stud 406 to drive the clamping assembly 4 to move, so that the two groups of clamping assemblies 4 approach each other under the action of the moving seat 2 approaching the second clamping plate 3, so as to realize the movement of the three clamping surfaces and clamp and fix the hardware.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
