Description

Technical Field

[0001] This utility model belongs to the field of compressor valve plate manufacturing technology, specifically relating to a punching device for manufacturing refrigeration compressor valve plates. Background Technology

[0002] The valve plate in a refrigeration compressor is a critical component responsible for controlling the direction and quantity of refrigerant flow. Its function is to ensure the compressor operates normally by regulating airflow during the suction and discharge processes. Punching is a key process step in the valve plate manufacturing process. Punching is primarily used to create holes in the valve plate to control gas flow. Different hole shapes and numbers determine the airflow characteristics and operating efficiency of the refrigeration compressor.

[0003] For valve plates with multiple holes, existing punching equipment requires workers to manually rotate or adjust the position of the valve plate. Manually rotating and adjusting the valve plate position increases operation time and depends on manual operation. Frequent adjustments will lead to a longer production cycle, affecting the overall processing progress and reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a punching device for the production of valve plates for refrigeration compressors, which can automatically rotate the valve plate, reduce frequent manual adjustments, make the production process more automated, and effectively improve production efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A punching device for producing valve plates of refrigeration compressors includes a punching table, a support frame mounted on the top of the punching table, a hydraulic cylinder mounted on the top of the support frame, an output end of the hydraulic cylinder extending through the inner side of the support frame, a horizontal plate fixedly connected to the surface of the output rod at the bottom of the hydraulic cylinder, and a punching head fixedly connected to the output end of the hydraulic cylinder. A rotation auxiliary mechanism is provided inside the punching table. The rotation auxiliary mechanism includes: a rotating rod connected to the inside of the support frame via bearings, with its two ends extending through the inner and outer sides of the support frame respectively; a rotating disk fixedly connected to one end of the rotating rod and located inside the support frame; a circular disk fixedly connected to the other end of the rotating rod; and an arc-shaped block fitted onto the surface of the rotating rod and fixedly connected. The following components are included: an outer side of the disc; a cylinder fixedly connected to the outer side of the disc; a rotating column whose bottom end is rotatably connected to the bottom of the inner wall of the punching platform; the top end of the rotating column extending to the top of the punching platform; a support platform fixedly connected to the top end of the rotating column; a worm gear sleeved on the surface of the rotating column; a worm meshing with the rear side of the worm gear, one end of the worm extending to the outer side of the punching platform; a rotating component fixedly connected to the end of the worm, the side surface of the rotating component having an arc-shaped groove for use with an arc-shaped block; a slot on one side of the rotating component, the rotating column engaging with the slot; and a connecting rod, one end of which is connected to the inner side of the rotating disc via a rotating shaft, the other end of which is connected to the bottom of the horizontal plate via a rotating shaft.

[0007] Preferably, vertical grooves are provided on both sides of the support frame, and sliding blocks are fixedly connected to the outer side of the horizontal plate, with the sliding blocks slidably connected to the inside of the vertical grooves.

[0008] Preferably, the top of the punching platform is provided with a circular groove, and the support platform is movably disposed inside the circular groove.

[0009] Preferably, a bracket is fitted onto the surface of the worm gear, and the bracket is fixedly connected to the bottom of the inner wall of the punching platform.

[0010] Preferably, there are four arc-shaped grooves and four slots, which are equidistantly distributed on the side surface of the rotating component.

[0011] Preferably, the surface of the rotating column is fitted with a ring, which is located at the top and bottom of the worm gear.

[0012] The technical effects achieved by this utility model are as follows:

[0013] In this invention, when punching holes in the valve plate, a hydraulic cylinder can be operated to drive the punching head to punch holes in the valve plate on the support platform. During the punching process, the output rod at the bottom of the hydraulic cylinder will drive the horizontal plate to move downward. The downward movement of the horizontal plate will drive the connecting rod to move downward. The downward movement of the connecting rod will drive the rotating disk connected by the rotating shaft to rotate. The rotation of the rotating disk will drive the disc, arc block and cylinder to rotate through the rotating rod. The rotation of the arc block and cylinder can cooperate with the arc groove and slot to drive the rotating parts to rotate intermittently. When the rotating parts are rotating, they can also drive the worm to rotate. The rotation of the worm can drive the meshed worm wheel and rotating column to rotate. When the rotating column rotates, it can also drive the top support platform to rotate. The rotation of the support platform can drive the valve plate being processed on the top to rotate intermittently. Thus, while punching the valve plate, the support platform and the valve plate can rotate. The rotating support platform can automatically adjust the position of the valve plate during punching, reducing manual intervention or multiple position adjustments, thereby improving production efficiency. There is no need to stop the machine frequently for repositioning. Multiple holes can be punched at one time, saving time. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-3As shown, a punching device for producing valve plates of refrigeration compressors includes a punching table 1, a support frame 101 mounted on the top of the punching table 1, a hydraulic cylinder 102 mounted on the top of the support frame 101, an output end of the bottom of the hydraulic cylinder 102 extending through the inner side of the support frame 101, a horizontal plate 104 fixedly connected to the surface of the output rod at the bottom of the hydraulic cylinder 102, and a punching head 103 fixedly connected to the output end at the bottom of the hydraulic cylinder 102. A rotation auxiliary mechanism is provided inside the punching table 1; the rotation auxiliary mechanism includes a rotating rod 201, which is connected to the inside of the support frame 101 via bearings, and rotates... The two ends of rod 201 extend to the inner and outer sides of support frame 101, respectively; rotating disk 202 is fixedly connected to the end of rotating rod 201 and located inside support frame 101; disc 203 is fixedly connected to the other end of rotating rod 201; arc-shaped block 204 is sleeved on the surface of rotating rod 201 and fixedly connected to the outer side of disc 203; cylinder 205 is fixedly connected to the outer side of disc 203; rotating column 206 has its bottom end rotatably connected to the bottom of the inner wall of punching platform 1; rotating column 206... The top end extends to the top of the punching platform 1; a support platform 207 is fixedly connected to the top end of the rotating column 206; a worm gear 208 is sleeved on the surface of the rotating column 206; a worm 209 is meshed with the rear side of the worm gear 208, and one end of the worm 209 extends to the outer side of the punching platform 1; a rotating component 210 is fixedly connected to the end of the worm 209, and an arc groove 213 is opened on the side surface of the rotating component 210 to cooperate with the arc block 204; a slot 211 is opened on one side of the rotating component 210, and the rotating column 206 extends to the top of the punching platform 1. 06 is connected to the slot 211; connecting rod 212, one end of connecting rod 212 is connected to the inside of the rotating disk 202 through a rotating shaft, and the other end of connecting rod 212 is connected to the bottom of the horizontal plate 104 through a rotating shaft. With the cooperation of the self-rotation auxiliary mechanism, the valve plate can be automatically positioned and adjusted. Workers do not need to operate manually frequently, which can reduce labor costs and labor intensity. At the same time, the self-rotation of the valve plate can ensure that the hole processing is more uniform and accurate, reducing hole defects caused by manual adjustment or uneven positioning. This not only improves product quality, but also improves product processing efficiency.

[0021] like Figures 1-2 As shown, vertical slots 301 are provided on both sides of the support frame 101, and sliding blocks 302 are fixedly connected to the outer side of the horizontal plate 104. The sliding blocks 302 are slidably connected to the inside of the vertical slots 301. When the output rod of the hydraulic cylinder drives the horizontal plate 104 to move up and down in the punching process, the horizontal plate 104 can slide vertically inside the vertical slots 301 with the sliding blocks 302, which avoids the horizontal plate 104 from shaking or deviating during the movement. This can ensure that the force transmission during the punching process is more uniform and stable, and avoid processing errors.

[0022] like Figures 1-2 As shown, a circular groove 4 is provided on the top of the punching platform 1, and the support platform 207 is movably disposed inside the circular groove 4. When the support platform 207 rotates, it can rotate flexibly inside the circular groove 4, so that the support platform 207 has sufficient adjustment space and prevents the support platform 207 from colliding with the punching platform 1 due to insufficient space when it drives the valve plate to rotate, thus preventing motion interference.

[0023] like Figures 2-3 As shown, a bracket 5 is fitted on the surface of the worm 209. The bracket 5 is fixedly connected to the bottom of the inner wall of the punching platform 1. The bracket 5 is fixed to the bottom of the inner wall of the punching platform 1, which can effectively prevent the worm 209 from shaking or deviating during operation, thereby maintaining the stability of the worm 209, avoiding positional errors caused by rotation or load changes, and ensuring the accuracy of the meshing transmission between the worm 209 and the worm wheel 208.

[0024] like Figure 1 and Figure 3 As shown, there are four arc-shaped grooves 213 and four slots 211, which are equidistantly distributed on the side surface of the rotating component 210. Under the action of the four arc-shaped grooves 213 and four slots 211, and with the cooperation and connection between the arc-shaped block 204 and the cylinder 205 and the arc-shaped grooves 213 and four slots 211, the rotation angle of the rotating component 210 can be evenly distributed, so that the rotating component 210 rotates intermittently, and each rotation angle is ninety degrees. This can stably and accurately drive the support platform 207 and the top valve plate to adjust their positions precisely.

[0025] like Figures 2-3 As shown, a ring 6 is sleeved on the surface of the rotating column 206. The ring 6 is located at the top and bottom of the worm gear 208. The ring 6 is located at the top and bottom of the worm gear 208, which helps to fix the position of the worm gear 208 and prevent the worm gear 208 from being displaced during rotation. The stable position of the worm gear 208 can ensure its meshing accuracy with the worm 209, thereby ensuring transmission efficiency and working accuracy.

[0026] The working principle of this utility model is as follows: When punching holes in the valve plate, the hydraulic cylinder 102 can be operated to drive the punch head to punch holes in the valve plate on the support platform 207. During the punching process, the output rod at the bottom of the hydraulic cylinder 102 will drive the horizontal plate 104 to move downward. The downward movement of the horizontal plate 104 can drive the connecting rod 212 to move downward. The downward movement of the connecting rod 212 can drive the rotating disk 202 connected by the rotating shaft to rotate. The rotation of the rotating disk 202 will drive the disc 203, the arc block 204 and the cylinder 205 to rotate through the rotating rod 201. The rotation of the arc block 204 and the cylinder 205 can cooperate with the arc groove 213 and the slot 211 to connect, thereby driving the rotating part 210 to rotate. Intermittent rotation: When the rotating component 210 rotates, it simultaneously drives the worm gear 209 to rotate. The rotation of the worm gear 209 drives the meshing worm wheel 208 and the rotating column 206 to rotate. When the rotating column 206 rotates, it simultaneously drives the top support platform 207 to rotate. The rotation of the support platform 207 drives the valve plate being processed at the top to rotate intermittently. Thus, while punching holes in the valve plate, the support platform 207 and the valve plate rotate on their own axis. The rotating support platform 207 allows the valve plate to automatically adjust its position during punching, reducing manual intervention or multiple position adjustments, thereby improving production efficiency. It eliminates the need for frequent machine stops for repositioning and can complete the punching of multiple holes at once, saving time.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
