Description

Technical Field

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

[0002] During the processing of metal parts, they need to be fixed and clamped with the help of fixtures so that the metal parts can remain stable during processing and improve the processing accuracy.

[0003] In the prior art, during use, a fixed fixture is provided with a moving mechanism to enable the clamped parts to move relative to each other to assist in processing. However, most metal parts have irregular shapes, and a single clamping mechanism will lead to poor clamping stability.

[0004] As disclosed in Chinese patent CN221338202U, a fixing fixture for processing metal parts is proposed. The metal parts to be processed are placed on the upper end of a movable table, and then four movable clamping rods are toggled so that the movable clamping rods abut against the outer wall of the irregular parts. In order to ensure that the metal parts can be abutted and clamped by the four movable clamping rods at the same time, the threaded push rod is rotated by rotating the handle, thereby driving the movable table to be raised and lowered, so that the metal parts placed on the movable table are raised and lowered and adjusted to a height that satisfies the simultaneous clamping of the four movable clamping rods. After the four movable clamping rods abut, the threaded displacement rod is driven to rotate by rotating the screw cap, so that the rubber suction cup is adsorbed on the outer wall of the metal part, thereby improving the clamping stability. Finally, the power switch is pressed to enable the distribution box to power the two electromagnets. After the electromagnets are powered, magnetic force is generated to adsorb the sleeve ring block through the plastic sleeve, thereby positioning the toggle position of the movable clamping rod, further improving the stability of clamping the metal parts, and completing the use of the fixing fixture for processing metal parts.

[0005] However, the metal parts processing fixing fixtures used in the prior art are not easy to disassemble and replace during use, and thus it is not easy to flexibly adjust and clamp metal fixtures of various shapes, thereby affecting the processing effect and processing efficiency.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Example 1:

[0029] A fixture for metal processing includes a support leg 1, an adjustable transmission structure mounted on the top of the support leg 1, clamping structures connected to the left and right sides of the top of the adjustable transmission structure, and a debris collection structure mounted in the middle of the back of the adjustable transmission structure. The clamping structure includes a lifting unit and a clamping unit, the clamping unit being disposed in the middle of the lifting unit. The clamping unit includes an electric push rod 205, a mounting seat 206 mounted on the output end of the electric push rod 205, a clamping seat 207 mounted in the middle of the side of the two mounting seats 206 close to each other, a damping rod 208 mounted in the middle of the side of the clamping seat 207 away from the mounting seat 206, a clamping block 209 mounted on the end of the damping rod 208 away from the clamping seat 207, and a spring 210 mounted in the middle of the side of the two clamping seats 207 close to each other, near the front and back ends. The lifting unit includes a lifting member 201 , a mounting plate 202 is connected to the middle of the outer surface of the lifting member 201 , a slider 203 is fixedly mounted to the middle of one end of the back of the mounting plate 202 , and a guide rod 204 is connected to the outer surface of the slider 203 .

[0030] The electric push rod 205 is installed in the middle of the mounting plate 202, and the outer surface of the middle side of the bracket 207 close to the mounting bracket 206 is slidably connected to the inner wall of the convex groove opened in the middle of the mounting bracket 206. The spring 210 is fixedly connected to the clamping block 209 at one end away from the bracket 207, and the outer surface of the slider 203 is slidably connected to the inside of the convex groove opened in the middle of the guide rod 204.

[0031] The adjustable transmission structure includes a workbench 101, with an asynchronous motor 102 mounted in the middle of the bottom surface of the workbench 101. The output end of the asynchronous motor 102 is connected to a rotating shaft 103. A rotating platform 104 is mounted on the top of the rotating shaft 103. A transmission member 105 is connected to the outer surface of the rotating shaft 103 near the bottom. The bottom surface of the workbench 101 is fixedly connected to the top of the support leg 1. The left and right ends of the transmission member 105 are connected to the bottom of the lifting member 201. The middle of the outer surface of the rotating shaft 103 is connected to the inner portion of the circular hole in the middle of the top surface of the workbench 101 through a bearing. The top surface of the workbench 101 is fixedly connected to the bottom end of the guide rod 204.

[0032] By setting up the clamping structure and utilizing the installation of the damping rod 208 and the spring 210, deformation or damage to the metal parts caused by excessive clamping force can be avoided during the clamping process. At the same time, a sliding connection is provided inside the convex groove in the middle of the clamping seat 207 and the mounting seat 206, and the clamping seat 207 and the mounting seat 206 are connected by bolts, which facilitates the disassembly and replacement of the clamping block 209.

[0033] When clamping a metal workpiece, the metal workpiece is placed in the middle of the top surface of the rotary table 104, and the asynchronous motor 102 is started to drive the rotating shaft 103 and the rotary table 104 to rotate, so as to adjust the horizontal angle of the metal workpiece for easy processing. At the same time, the rotating shaft 103 drives the transmission member 105 to transmit when it rotates. When the output end of the asynchronous motor 102 drives the rotating shaft 103 to rotate, it drives the driving wheel to rotate. When the driving wheel rotates, the belt is connected to the driven wheel by a belt transmission, thereby driving the driven wheel to rotate. The driven wheel rotation drives the lifting member 201 to rotate, and the driven wheel rotation drives the threaded rod to rotate, and the threaded rod is connected to the threaded barrel by a thread, and a cam is provided in the middle of the slider 203 and the guide rod 204. The sliding limit connection inside the groove enables the threaded cylinder to drive the mounting plate 202 to rise and fall, and adjust the height of the clamping structure, which is convenient for clamping and fixing metal parts of different heights. Starting the electric push rod 205 to extend and shorten can drive the clamping block 209 to clamp and fix the workpiece, and in the clamping and fixing process, the damping rod 208 and the spring 210 are squeezed to prevent the clamping force from being too large and causing damage to the metal parts. The sliding connection inside the convex groove is opened between the clamping seat 207 and the middle part of the mounting seat 206, and the clamping seat 207 and the mounting seat 206 are detachably connected by bolts, so as to facilitate the rapid replacement and disassembly of the clamping block 209, thereby facilitating flexible processing and improving work efficiency.

[0036] By setting up the debris collection structure, the fan 302 is started to blow the metal processing part, thereby cooling the metal processing part and blowing the debris at the same time. At the same time, the air pump 307 is started to pump the air inside the collection box 305, and the negative pressure inside the collection box 305 is used to collect the debris through the dust hopper 303 and the dust pipe 304.

[0037] When processing metal parts, start the fan 302 to blow the metal processing part, thereby blowing the workpiece processing debris, and at the same time cool the metal processing part, start the air pump 307 to pump the air inside the collection box 305, so that the inside of the collection box 305 is in a negative pressure state, thereby utilizing the negative pressure to adsorb and collect the metal processing debris through the dust suction pipe 304 and the dust suction hopper 303. After the debris enters the collection box 305, the debris is collected using a multi-layer filter screen installed at the bottom of the collection drawer 306 for centralized processing.
