In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed. It is known as the "mother of industry".

[0003] When precision molds are being welded, a clamping device is required to fix the precision molds and improve the welding effect. In existing clamping devices, the jaws are generally arranged above the clamping platform, which makes it impossible to directly translate the material onto the clamping platform. For example, a clamping device for producing transformers disclosed in a Chinese patent application with publication number CN112091359B requires a loading device to clamp the material from the conveyor belt, move it to the top of the clamping platform and then put it down. Only then can the material be clamped and processed. This process requires multiple operating instructions to complete multiple actions. The process is cumbersome and time-consuming, which greatly reduces the welding efficiency of precision molds.

DETAILED DESCRIPTION

[0020] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0021] Example: Reference Figure 1-Figure 3A processing table including a clamping device for precision mold welding is shown, including a processing table 1, a feeding mechanism 2 and a discharging mechanism 4, both of which are installed on the processing table 1, and also includes a double-sided clamping mechanism 3, which is installed on the processing table 1 through a rotating shaft, and the double-sided clamping mechanism 3 includes a shell 301, two end covers 302, a clamping assembly 304 and an adjusting assembly 305, the two end covers 302 are respectively fixedly installed at the upper and lower ends of the shell 301, the clamping assembly 304 and the adjusting assembly 305 are transmission-matched and are both installed inside the shell 301, the clamping assembly 304 includes a plurality of clamping claws 3045, each The clamping jaws 3045 are symmetrically arranged at the upper and lower ends of the clamping assembly 304, and the clamping assembly 304 can drive the multiple clamping jaws 3045 to move synchronously along the radial direction of the end cover 302. The adjusting assembly 305 includes an adjusting rod 3051. Initially, the upper end of the adjusting rod 3051 passes through the upper end cover 302, and the lower end of the adjusting rod 3051 is flush with the lower end cover 302. After the feeding mechanism 2 conveys the precision mold to the middle of the upper surface of the end cover 302, the gravity of the precision mold can drive the adjusting rod 3051 to descend. When the adjusting rod 3051 descends, it can drive the clamping jaws 3045 to rise so that the upper end of the clamping jaws 3045 clamps the precision mold. There are two rotating shafts, which are symmetrically fixed on the outer wall of the shell 301. The processing table 1 is provided with a mounting groove for accommodating the double-sided clamping mechanism 3. The shell 301 is rotatably installed in the mounting groove through the rotating shaft. The inner wall of the mounting groove is provided with an arc surface that is compatible with the rotation path of the double-sided clamping mechanism 3. After the welding process is completed, the double-sided clamping mechanism 3 is driven by the rotating shaft to flip 180°, so that the precision mold 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 molds after the welding process and discharge them one by one.

[0022] Under normal conditions, the clamping jaws 3045 are completely placed inside the shell 301, and there is no object blocking the surface of the end cover 302. The precision mold is translated to the middle of the end cover 302 through the loading mechanism 2, and the precision mold presses down one end of the adjusting rod 3051 to drive the clamping jaws 3045 to rise and pass through the end cover 302, and then drive multiple clamping jaws 3045 to move radially and move closer to the axis of the end cover 302 to clamp the precision mold. After the precision mold welding process is completed, the double-sided clamping mechanism 3 is driven to flip, the positions of the two end covers 302 are interchanged, and the precision mold is flipped to the bottom of the double-sided clamping mechanism 3, and the multiple clamping jaws 3045 are driven again to move radially to release the precision mold. The precision mold falls into the discharging mechanism 4 under the action of gravity to complete the discharging, and the above operations are repeated. The precision mold can be continuously clamped and welded. Compared with the prior art, the present invention greatly simplifies the loading and unloading actions, shortens the loading and unloading time, and improves the welding processing efficiency of the precision mold.

[0023] Furthermore, the feeding mechanism 2 is arranged on one side of the double-sided clamping mechanism 3, such as Figure 4 As shown, the feeding mechanism 2 includes a conveyor belt 201 and an electric telescopic rod 204, both of which are fixedly installed on the processing table 1, and side baffles 202 are fixedly installed on both sides of the conveyor belt 201, and a positioning baffle 203 is fixedly installed on one end of the conveyor belt 201. The electric telescopic rod 204 is arranged on one side of the conveyor belt 201, and the electric telescopic rod 204 is arranged vertically with the side baffle 202, and the electric telescopic rod 204 is arranged on the extension line of the diameter of the end cover 302, and the telescopic end of the electric telescopic rod 204 is fixedly installed with a push plate 205, one of which is on the side baffle 202. An opening is provided, 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 from the conveyor belt 201, and 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, and the pressure sensor is connected to the driving system of the conveyor belt 201. When the precision mold contacts the positioning baffle 203, the conveyor belt 201 is controlled to stop, the electric telescopic rod 204 is driven to extend, and the push plate 205 pushes the precision mold to move horizontally to the middle of the end cover 302 to complete the loading. The loading process is simple and fast.

[0024] Furthermore, if Figure 5-Figure 6As shown, the clamping assembly 304 includes a sliding plate 3041, a plurality of screw rods 3043, a plurality of sliders 3044, a plurality of linkage gears 3047 and a second motor 3048. The sliding plate 3041 is provided with a plurality of through holes 3042 in a circular array. Each of the screw rods 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 screw rods 3043 is inserted through a corresponding slider 3044, and each of the screw rods 3043 is threadedly matched with a corresponding slider 3044. Each of the clamping jaws 3045 is fixedly installed at the upper and lower ends of the corresponding slider 3044. A central hole 3046 is provided in the middle of the sliding plate 3041. One end of each of the screw rods 3043 is inserted into the central hole 3046. , multiple linkage gears 3047 are arranged in the center hole 3046, each linkage gear 3047 is fixedly connected to one end of the corresponding screw rod 3043, and two adjacent linkage gears 3047 are meshed with each other, the second motor 3048 is fixedly installed in the sliding plate 3041, and the output end of the second motor 3048 is fixedly connected to the other end of one of the screw rods 3043, driving the second motor 3048 to drive one of the screw rods 3043 to rotate, and through the transmission cooperation of multiple linkage gears 3047, the multiple screw rods 3043 are driven to rotate synchronously, and the multiple sliders 3044 move synchronously, driving the multiple clamps 3045 to synchronously approach or move away from the central axis of the sliding plate 3041, so as to clamp or release the precision mold, and the linkage between the multiple clamps 3045 is high, and the clamping effect is better.

[0025] Furthermore, the thread directions of the two adjacent screw rods 3043 are opposite, and the clamping 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 the two adjacent screw rods 3043 are driven by the two adjacent linkage gears 3047, and the rotation directions of the two adjacent linkage gears 3047 are opposite, in order to achieve the simultaneous approach and distance between the two adjacent sliders 3044 and the central axis of the sliding plate 3041, the thread directions of the two adjacent screw rods 3043 need to be set in opposite directions. Since the moving range of the end of the horizontal rod is the clamping range of the clamping jaw 3045, the clamping range of the clamping jaw 3045 is staggered with the moving range of the slider 3044 through the structural setting of the clamping jaw 3045, so as to facilitate the clamping of the precision mold.

[0026] Furthermore, the double-sided clamping mechanism 3 also includes a plurality of guide rods 306, which are arranged in a circular array in the shell 301, and the two ends of the plurality of guide rods 306 are respectively fixedly connected to the two end covers 302, and the plurality of guide rods 306 are all inserted through the sliding plate 3041, and the sliding plate 3041 and the guide rods 306 are slidably matched, so that the clamping assembly 304 can move up and down in the shell 301.

[0027] Furthermore, if Figure 7 As shown, the adjustment component 305 is arranged in the center hole 3046, and the adjustment component 305 also 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 covers 302, and 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 fixedly connected to the driven gear 3054, and the linkage frame 3055 is fixedly connected to the sliding plate 3041. The middle of the adjusting rod 3051 and the middle of the linkage frame 3055 are both provided with teeth. The adjusting rod 3051 is meshed with the driving gear 3053, and the linkage frame 3055 is meshed with the driven gear 3054. When the adjusting rod 3051 is moved, the adjusting rod 3051 drives the driving gear 3053 to rotate, and 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. The diameter of the driven gear 3054 is greater than the diameter of the driving gear 3053. Since the driving gear 3053 and the driven gear 3054 are coaxially arranged, the angular velocities of the two are always the same. When rotating at the same angle, the linear velocity of the driven gear 3054 is greater than the linear velocity 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.

[0028] Furthermore, the end cap 302 is provided with a plurality of clamping holes 3021 in an annular array, the length and width of the clamping holes 3021 are both greater than the length and width of the cross bar, the middle of the end cap 302 is provided with a circular groove 3022 and an adjustment hole 3023, the adjustment hole 3023 is arranged in the middle of the circular groove 3022, the cross-sectional size of the adjustment hole 3023 is the same as the cross-sectional size of the adjustment rod 3051, and the adjustment rod 3051 is limited to prevent the adjustment rod 3051 from deflecting, and it is necessary to ensure that the diameter of the circular groove 3022 is greater than the outer diameter of the precision mold, and the upper end height of the adjustment rod 3051 does not exceed the circular groove 3022 at the beginning. The upper end height of the groove 3022, when the precision mold moves to the middle of the end cover 302, falls into the circular groove 3022, and the precision mold presses down the adjusting rod 3051, driving the clamping assembly 304 to move upward, and the cross bar passes through the clamping jaw hole 3021 to the top of the end cover 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 it will cause the loading 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, the distance that the adjusting rod 3051 needs to move is less than the moving distance of the clamping assembly 304.

[0029] Furthermore, if Figure 8 As shown, the discharging mechanism 4 includes a round cover 401, a frame 402 and a bottom plate 403. The round cover 401 and the frame 402 are both fixedly installed inside the processing table 1. The round cover 401 is fixedly installed below the shell 301. The inner diameter of the round cover 401 is the same as the diameter of the shell 301. The bottom plate 403 is fixedly installed at the bottom of the round cover 401. A buffer pad 404 is fixedly installed above the bottom plate 403. A discharging port is provided on one side of the round cover 401. The frame 402 is arranged on one side of the round cover 401. A discharge channel 405 is provided, and the position of the discharge channel 405 corresponds to the position of the discharge port. The bottom end of the discharge 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 of the fall is buffered by the buffer pad 404 to prevent damage to the precision mold. The setting of the diameter of the round cover 401 ensures that it does not block the rotation of the double-sided clamping mechanism 3. After the next precision mold is processed, the double-sided clamping mechanism 3 is flipped over to push the precision mold that has fallen into the discharge channel 405 to complete the discharge. The process is simple and fast.

[0030] Furthermore, a first motor 5 is fixedly installed on the top of the processing table 1, and 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, the double-sided clamping mechanism 3 can be conveniently driven to rotate to complete material unloading.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
