[0001] The utility model relates to the technical field of hardware processing, in particular to a hardware processing fixture. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. During the processing of shaft hardware, it is necessary to use processing fixtures to clamp and fix the workpiece to ensure its stability during the processing.

[0003] The Chinese patent "A shaft hardware processing fixture" authorization announcement number "CN 213561200 U" first places the shaft hardware on the second semicircular clamping groove on the second sliding member when clamping the shaft hardware, drives the motor to rotate the lead screw, and makes the first sliding member and the second sliding member on the lead screw approach each other to clamp the shaft hardware. The structure is simple and easy to use.

[0004] The above scheme can realize the clamping operation of shaft hardware, but the diameter of the semicircular clamping grooves opened by the first sliding member and the second sliding member is constant. When clamping shaft hardware, only shaft hardware with the same diameter can be clamped, which has low practicality.

[0005] Therefore, a hardware processing fixture is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

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

[0025] When implementing: Figure 1-5 As shown, a hardware processing fixture comprises: a connecting plate 1, a mounting plate 2 is fixedly connected to the middle of the top of the connecting plate 1, and the mounting plate 2; a fixing mechanism 3, the fixing mechanism 3 for fixing shaft hardware of different diameters is arranged at the top of the mounting plate 2; wherein the fixing mechanism 3 comprises a fixing frame 301 fixedly connected to the middle of the top of the mounting plate 2, a cylinder 302 is fixedly connected to the four corners of the inner wall of the fixing frame 301, both ends of the cylinder 302 penetrate the fixing frame 301, a piston rod 303 is slidably connected to the inner wall of the cylinder 302, one end of the piston rod 303 penetrates the cylinder 302 and is fixedly connected to a fixing plate 305, the other end of the piston rod 303 is fixedly connected to a spring 304, the other end of the spring 304 is fixedly connected to the inner wall of the cylinder 302, and a driving assembly 306 is arranged at the top of the mounting plate 2. The distribution direction of the four fixing plates 305 forms an "X" shape. When the device is used to fix shaft hardware, the connecting plate 1 is installed on the operating table for processing the shaft hardware by means of bolts.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the driving assembly 306 includes an air cylinder 3061 fixedly connected to the top of the mounting plate 2, an extrusion plate 3062 is slidably connected to the inner wall of the air cylinder 3061, a threaded rod 3063 is threadedly connected to one end of the air cylinder 3061, and the other end of the threaded rod 3063 penetrates into the interior of the air cylinder 3061 and is rotatably connected to one end of the extrusion plate 3062, a mounting pipe 3065 is fixedly connected to the surface of the fixed frame 301, a circular pipe 3064 is connected between the cylinder 302 and the mounting pipe 3065, and a connecting pipe 3066 is connected between the mounting pipe 3065 and the air cylinder 3061. An angle is formed between the top of the fixed plate 305 and the horizontal plane, and a guide plate 307 is fixedly connected to the upper end of one side of the fixed plate 305, and the guide plate 307 is inclined.

[0027] When the device is in the initial state, the gas storage cylinder 3061 is filled with gas, the spring 304 is in an extended state, the four fixing plates 305 are close to each other, the inner wall of the fixing frame 301 is circular, and the center points of the four fixing plates 305 are at the same distance from the center point of the fixing frame 301.

[0028] When processing shaft hardware, the shaft hardware is inserted from above the four fixed plates 305. At this time, the bottom end of the shaft hardware contacts one side of the four guide plates 307, and the shaft hardware continues to move downward. At this time, the surface of the shaft hardware will push the fixed plate 305 to move toward the direction close to the cylinder 302 and compress the spring 304. When the shaft hardware can no longer move downward, the four fixed plates 305 complete the initial limiting of the shaft hardware under the action of the spring 304.

[0029] After completing the initial limiting, the staff rotates the threaded rod 3063 to push the extrusion plate 3062 to move, so that the extrusion plate 3062 squeezes the gas in the gas cylinder 3061. When the gas in the gas cylinder 3061 is squeezed, it will enter the installation tube 3065 through the connecting tube 3066, and enter the corresponding cylinder 302 through multiple circular tubes 3064 at the same time. When the gas enters the cylinder 302, it will push the piston rod 303, so that the piston rod 303 pushes the fixing plate 305 to tighten the shaft hardware, thereby completing the fixation of the shaft hardware.

[0030] like Figure 4 and Figure 5 As shown, the other side of the fixing plate 305 is concave in an arc shape, and a rubber pad 308 is fixedly connected to the other side of the fixing plate 305. The surface of the rubber pad 308 is provided with grooves 3081 distributed in equal rows, and the grooves 3081 are opened in the longitudinal direction. The inclination angle of the top of the rubber pad 308 is the same as the inclination angle of the top of the fixing plate 305. When the shaft hardware enters the inner side of the four fixing plates 305, the surface of the shaft hardware will contact the surface of the rubber pad 308.

[0031] like Figure 3 As shown, one end of the extrusion plate 3062 is fixedly connected to a round rod 3067, and the other end of the round rod 3067 passes through the gas storage cylinder 3061. The surface of the round rod 3067 is slidably connected to the inner wall of the gas storage cylinder 3061, and when the threaded rod 3063 drives the extrusion plate 3062 to move horizontally, it will drive the round rod 3067 to move synchronously.

[0032] like Figure 5 As shown, the bottom end of the fixing plate 305 is rotatably connected with equidistantly distributed balls 309, and the surface of the balls 309 contacts the top of the mounting plate 2. When the shaft hardware is inserted downward to push the fixing plate 305 to move, the fixing plate 305 will cause the balls 309 to rotate during the movement.

[0033] When the utility model is used, when processing shaft hardware, the shaft hardware is inserted from above the four fixing plates 305. At this time, the bottom end of the shaft hardware contacts one side of the four guide plates 307, and the shaft hardware continues to move downward. At this time, the surface of the shaft hardware pushes the fixing plate 305 to move in the direction close to the cylinder 302 and compresses the spring 304. When the shaft hardware cannot continue to move downward, the four fixing plates 305 complete the initial limit of the shaft hardware under the action of the spring 304. At this time, the staff rotates the threaded rod 3063 to push the extrusion plate 3062 to move, so that the extrusion plate 3062 squeezes the gas in the gas cylinder 3061. When the gas in the gas cylinder 3061 is squeezed, it will enter the installation tube 3065 through the connecting tube 3066, and enter the corresponding cylinder 302 through multiple circular tubes 3064 at the same time. When the gas enters the cylinder 302, it will push the piston rod 303, so that the piston rod 303 pushes the fixing plate 305 to tighten the shaft hardware, thereby completing the fixation of the shaft hardware.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
