Description

Technical Field

[0001] The present invention relates to the technical field of precision mold welding processing, and particularly relates to a processing table including a clamping device for precision mold welding. Background Art

[0002] A mold is a variety of molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting, or forging, smelting, stamping, etc. In short, a mold is a tool for making formed articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of the article by changing the physical state of the formed material, and is known as the "mother of industry".

[0003] When a precision mold is welded and processed, a clamping device is required to fix the precision mold, thereby improving the welding effect. In the existing clamping devices, generally, the clamping jaws are arranged above the clamping platform, resulting in the inability to directly translate the material onto the clamping platform. For example, in a clamping device for producing transformers disclosed in a Chinese patent application with the publication number CN112091359B, a feeding device is required during feeding. The material is clamped from the conveyor belt, moved above the clamping platform and then placed down, and then the material can be clamped and processed. This process requires multiple operation instructions to cooperate to complete multiple actions, which is cumbersome and time-consuming, greatly reducing the welding processing efficiency of precision molds.

[0004] Therefore, the present application provides a processing table including a clamping device for precision mold welding to meet the requirements. Summary of the Invention

By setting a double-sided clamping mechanism, in the double-sided clamping mechanism, two end covers are respectively fixedly installed at both ends of the housing. The clamping assembly and the adjustment assembly are both installed inside the housing. Multiple jaws are installed on both sides of the clamping assembly, and the clamping assembly can drive the multiple jaws to move synchronously in the radial direction. The adjustment assembly includes an adjustment rod. The two ends of the adjustment rod respectively penetrate through the two end covers. When one end of the adjustment rod moves, the jaws can penetrate through the end cover at the same end, translate the precision die to the middle of the end cover, press down one end of the adjustment rod by the precision die, drive the jaws to penetrate through the end cover, and then drive the multiple jaws to move radially and move closer to the axis of the end cover to clamp the precision die. After the precision die welding process is completed, drive the double-sided clamping mechanism to flip, swap the positions of the two end covers, flip the precision die to the lower side of the double-sided clamping mechanism, drive the multiple jaws to move radially again to release the precision die, and the precision die falls into the discharging mechanism under the action of gravity to complete discharging.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment: Refer to Figures 1 - 3A processing table including a clamping device for precision die welding, comprising a processing table 1, a feeding mechanism 2 and a discharging mechanism 4. The feeding mechanism 2 and the discharging mechanism 4 are both installed on the processing table 1. It further includes a double-sided clamping mechanism 3. The double-sided clamping mechanism 3 is installed on the processing table 1 through a rotating shaft. The double-sided clamping mechanism 3 includes a housing 301, two end caps 302, a clamping assembly 304 and an adjusting assembly 305. The two end caps 302 are respectively fixedly installed at the upper and lower ends of the housing 301. The clamping assembly 304 and the adjusting assembly 305 are in transmission cooperation and are both installed inside the housing 301. The clamping assembly 304 includes a plurality of jaws 3045. Each of the jaws 3045 is symmetrically arranged at the upper and lower ends of the clamping assembly 304. And the clamping assembly 304 can drive the plurality of jaws 3045 to move synchronously along the radial direction of the end cap 302. The adjusting assembly 305 includes an adjusting rod 3051. Initially, the upper end of the adjusting rod 3051 penetrates through the upper end cap 302, and the lower end of the adjusting rod 3051 is flush with the lower end cap 302. After the feeding mechanism 2 transports the precision die to the middle of the upper surface of the end cap 302, the gravity of the precision die can drive the adjusting rod 3051 to descend. When the adjusting rod 3051 descends, it can drive the jaws 3045 to rise so that the upper ends of the jaws 3045 clamp the precision die.

[0033] There are two rotating shafts. The two rotating shafts are symmetrically and fixedly installed on the outer wall of the housing 301. An installation groove for accommodating the double-sided clamping mechanism 3 is provided on the processing table 1. The housing 301 is rotationally installed in the installation groove through the rotating shaft. The inner wall of this installation groove is provided with an arc surface adapted to the rotation path of the double-sided clamping mechanism 3. After the welding process is completed, the double-sided clamping mechanism 3 is driven to flip 180° through the rotating shaft, so that the precision die that has completed the welding process is transferred to the lower side of the double-sided clamping mechanism 3. The discharging mechanism 4 can collect the precision die after the welding process and discharge it one by one.

[0034] Under normal conditions, the jaws 3045 are completely placed inside the housing 301, and there is no object blocking the surface of the end cap 302. The precision die is translated to the middle of the end cap 302 through the feeding mechanism 2. The precision die presses one end of the adjusting rod 3051, driving the jaws 3045 to rise and penetrate through the end cap 302. Then, the plurality of jaws 3045 are driven to move radially and move closer to the axis of the end cap 302 to clamp the precision die. After the precision die welding process is completed, the double-sided clamping mechanism 3 is driven to flip, and the positions of the two end caps 302 are interchanged. The precision die is flipped to the lower side of the double-sided clamping mechanism 3. The plurality of jaws 3045 are driven to move radially again to release the precision die. The precision die falls into the discharging mechanism 4 under the action of gravity to complete the discharging. By repeating the above operations, the precision die can be continuously clamped and welded. Compared with the prior art, the present invention greatly simplifies the feeding and discharging actions, shortens the feeding and discharging time, and improves the welding processing efficiency of the precision die.

[0035] Further, the loading mechanism 2 is arranged on one side of the double-sided clamping mechanism 3. As Figure 4 shown, the loading mechanism 2 includes a conveyor belt 201 and an electric telescopic rod 204. Both the conveyor belt 201 and the electric telescopic rod 204 are fixedly installed on the processing table 1. Side baffles 202 are fixedly installed on both sides of the conveyor belt 201. A positioning baffle 203 is fixedly installed at one end of the conveyor belt 201. The electric telescopic rod 204 is arranged on one side of the conveyor belt 201. The electric telescopic rod 204 is perpendicular to the side baffle 202, and the electric telescopic rod 204 is arranged on the extension line of the diameter of the end cover 302. A push plate 205 is fixedly installed at the telescopic end of the electric telescopic rod 204. An opening is provided on one of the side baffles 202, and the position of the opening corresponds to the position of the push plate 205. The conveyor belt 201 is used to convey the precision mold. The side baffle 202 can prevent the precision mold from falling off the conveyor belt 201. When the precision mold moves to the positioning baffle 203, it will be blocked and positioned by the positioning baffle 203. A pressure sensor can be installed on the positioning baffle 203. The pressure sensor is connected to the drive system of the conveyor belt 201. When the precision mold contacts the positioning baffle 203, the conveyor belt 201 is controlled to stop, and the electric telescopic rod 204 is driven to extend. The push plate 205 pushes the precision mold to translate to the middle of the end cover 302 to complete the loading. The loading process is simple and fast.

[0036] Further, as Figures 5 - 6As shown, the clamping assembly 304 includes a sliding plate 3041, a plurality of lead screws 3043, a plurality of sliders 3044, a plurality of linkage gears 3047, and a second motor 3048. A plurality of through holes 3042 are formed in the sliding plate 3041 in an annular array. Each of the lead screws 3043 is rotatably installed in a corresponding through hole 3042. Each of the sliders 3044 is slidably assembled in a corresponding through hole 3042. Each of the lead screws 3043 penetrates through the corresponding slider 3044, and each of the lead screws 3043 is in threaded cooperation with the corresponding slider 3044. Each of the jaws 3045 is fixedly installed at the upper and lower ends of the corresponding slider 3044. A central hole 3046 is formed in the middle of the sliding plate 3041. One end of each of the plurality of lead screws 3043 penetrates into the central hole 3046. A plurality of linkage gears 3047 are arranged in the central hole 3046. Each of the linkage gears 3047 is fixedly connected to one end of the corresponding lead screw 3043, and two adjacent linkage gears 3047 are meshed with each other. The second motor 3048 is fixedly installed in the sliding plate 3041. The output end of the second motor 3048 is fixedly connected to the other end of one of the lead screws 3043. Driving the second motor 3048 to drive one of the lead screws 3043 to rotate, through the transmission cooperation of the plurality of linkage gears 3047, driving the plurality of lead screws 3043 to rotate synchronously, and the plurality of sliders 3044 move synchronously, driving the plurality of jaws 3045 to approach or move away from the central axis of the sliding plate 3041 synchronously, so as to clamp or release the precision mold. The linkage between the plurality of jaws 3045 is high, and the clamping effect is better.

[0037] Further, the thread directions of two adjacent lead screws 3043 are opposite. The jaw 3045 includes a vertical rod and a horizontal rod. The horizontal rod is fixedly installed at one end of the vertical rod, and the end of the horizontal rod is a clamping surface. Since two adjacent lead screws 3043 are driven by two adjacent linkage gears 3047, and the rotation directions of two adjacent linkage gears 3047 are opposite, in order to realize that two adjacent sliders 3044 approach or move away from the central axis of the sliding plate 3041 at the same time, the thread directions of two adjacent lead screws 3043 need to be set in the opposite direction. Since the moving range of the end of the horizontal rod is the clamping range of the jaw 3045, through the structural setting of the jaw 3045, the clamping range of the jaw 3045 is staggered from the moving range of the slider 3044, which is convenient for clamping the precision mold.

[0038] Further, the double-sided clamping mechanism 3 further includes a plurality of guide rods 306. The plurality of guide rods 306 are arranged in an annular array in the housing 301. Two ends of each of the plurality of guide rods 306 are fixedly connected to the two end caps 302 respectively. Each of the plurality of guide rods 306 penetrates through the sliding plate 3041, and the sliding plate 3041 is slidably matched with the guide rods 306, so that the clamping assembly 304 can move up and down in the housing 301.

[0039] Further, as Figure 7 shown, the adjusting assembly 305 is disposed in the central hole 3046. The adjusting assembly 305 further includes a mounting frame 3052, a driving gear 3053, a driven gear 3054, and a linkage frame 3055. The mounting frame 3052 is fixedly connected to one of the end caps 302. The driving gear 3053 and the driven gear 3054 are both rotatably mounted on the mounting frame 3052, and the driving gear 3053 is coaxially and fixedly connected to the driven gear 3054. The linkage frame 3055 is fixedly connected to the sliding plate 3041. Tooth patterns are provided in the middle of the adjusting rod 3051 and the middle of the linkage frame 3055. The adjusting rod 3051 meshes with the driving gear 3053, and the linkage frame 3055 meshes with the driven gear 3054. By moving the adjusting rod 3051, the adjusting rod 3051 drives the driving gear 3053 to rotate, the driving gear 3053 drives the driven gear 3054 to rotate, and the driven gear 3054 drives the linkage frame 3055 to move, thereby driving the clamping assembly 304 to move up and down in the housing 301 to adjust the position of the clamping jaw 3045;

[0040] The diameter of the driven gear 3054 is larger than that of the driving gear 3053. Since the driving gear 3053 and the driven gear 3054 are coaxially arranged, their angular velocities are always the same. When rotating the same angle, the linear velocity of the driven gear 3054 is greater than that of the driving gear 3053. Therefore, the moving distance of the adjusting rod 3051 is less than the moving distance of the clamping assembly 304.

[0041] Further, a plurality of clamping jaw holes 3021 are annularly and arrayedly provided on the end cap 302. The length and width of the clamping jaw holes 3021 are both larger than the length and width of the cross bar. A circular groove 3022 and an adjusting hole 3023 are provided in the middle of the end cap 302. The adjusting hole 3023 is disposed in the middle of the circular groove 3022. The size of the cross section of the adjusting hole 3023 is the same as the size of the cross section of the adjusting rod 3051, which plays a role in limiting the adjusting rod 3051 to prevent the adjusting rod 3051 from deflecting. It is necessary to ensure that the diameter of the circular groove 3022 is larger than the outer diameter of the precision mold, and initially the upper height of the adjusting rod 3051 does not exceed the upper height of the circular groove 3022. When the precision mold moves to the middle of the end cap 302, it falls into the circular groove 3022. The precision mold presses down the adjusting rod 3051, driving the clamping assembly 304 to move upward. The cross bar passes through the clamping jaw hole 3021 to the upper side of the end cap 302. At this time, the clamping jaw 3045 can be driven to clamp the precision mold. Since the moving range of the adjusting rod 3051 cannot exceed the height of the circular groove 3022, exceeding this will cause the feeding of the precision mold to be blocked, and the moving range of the clamping jaw 3045 obviously exceeds the height of the circular groove 3022. Therefore, the moving distance of the adjusting rod 3051 needs to be less than the moving distance of the clamping assembly 304.

[0042] Furthermore, as Figure 8 shown, the discharging mechanism 4 includes a circular cover 401, a frame 402 and a bottom plate 403. The circular cover 401 and the frame 402 are both fixedly installed inside the processing table 1. The circular cover 401 is fixedly installed below the outer shell 301. The inner diameter of the circular cover 401 is the same as the diameter of the outer shell 301. The bottom plate 403 is fixedly installed at the bottom of the circular cover 401. A buffer pad 404 is fixedly installed above the bottom plate 403. There is a discharging port on one side of the circular cover 401. The frame 402 is arranged on one side of the circular cover 401. There is a discharging channel 405 on the frame 402. The position of the discharging channel 405 corresponds to the position of the discharging port. The bottom end of the discharging channel 405 is inclined. When discharging, the clamping jaw 3045 releases the precision mold, and the precision mold falls on the bottom plate 403. The impact force during the fall is buffered by the buffer pad 404 to prevent damage to the precision mold. The setting of the diameter of the circular cover 401 ensures that it does not block the rotation of the double-sided clamping mechanism 3. And after the next precision mold is processed, the double-sided clamping mechanism 3 flips to push the fallen precision mold into the discharging channel 405 to complete the discharging. The process is simple and fast.

[0043] Furthermore, a first motor 5 is fixedly installed on the top of the processing table 1. The output end of the first motor 5 is fixedly connected to the rotating shaft of the double-sided clamping mechanism 3. By driving the first motor 5, it is convenient to drive the double-sided clamping mechanism 3 to rotate to complete the blanking.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
