Description

Technical Field

[0001] This utility model belongs to the field of spinning machine technology, and specifically relates to a spinning machine clamping device. Background Technology

[0002] A spinning machine is a device that uses rotation and pressure to plastically deform metal workpieces. It is commonly used to produce hollow workpieces such as cylinders, cones, and spheres. The clamping device of a spinning machine is an important component used to ensure the stable fixation of the workpiece during the spinning process.

[0003] Existing clamping devices can only clamp and process one workpiece at a time, so the processing cycle of spinning machines is relatively long and it limits the production capacity of the equipment. For production lines with large production demands, it cannot meet the needs of rapid production. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for a spinning machine that can clamp and process two workpieces simultaneously, thereby reducing the workpiece clamping and unloading time during each processing cycle. This device is suitable for large-scale production and effectively improves overall production efficiency.

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

[0006] A clamping device for a spinning machine includes a processing table with a hollow interior. A clamping mechanism is installed inside the processing table. The clamping mechanism includes: two central shafts connected to the inner wall of the processing table via bearings; two rotating rods respectively sleeved on the surfaces of the two central shafts; a connecting rod, one end of which is connected to both ends of the rotating rod via a pivot; vertical rods connected to the other ends of the connecting rods via pivots; connecting blocks, the bottom of which is fixedly connected to the top of the vertical rods, and the top of each connecting block extending through to the top of the processing table; clamping components fixedly connected to the top of the connecting blocks; and a double-headed electric cylinder fixedly installed on the inner wall of the processing table, both ends of which are fixedly connected to the left vertical rod.

[0007] Preferably, the inner wall of the processing table is fixedly connected to a limiting rod, and the vertical rods are all slidably connected to the surface of the limiting rod.

[0008] Preferably, limiting rings are fitted on the surfaces of both central shafts, and the limiting rings are located at the top and bottom of the rotating rod, respectively.

[0009] Preferably, the top of the processing table is provided with a horizontal groove, and the connecting blocks are slidably connected to the inside of the horizontal groove.

[0010] Preferably, the inner side of each clamping member is provided with a groove, and the inner wall of the groove is connected with a protective layer.

[0011] Preferably, there are four clamping members, and the two clamping members are arranged in pairs and are positioned opposite each other on the top of the processing table.

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

[0013] In this invention, when a workpiece needs to be fixed on a processing table during processing, the workpiece can first be placed between two pairs of clamping members on the processing table. Then, the double-headed electric cylinder is operated and the output rod is pushed to the right. When the output rod of the double-headed cylinder moves to the right, it can simultaneously drive the two pairs of left vertical rods to move to the right. The movement of the left vertical rods to the right can drive the connecting block and the clamping members to move to the right at the same time. When the left vertical rods move to the right, they can drive the rotating rod to rotate on the surface of the central shaft through the connecting rod. When the two rotating rods rotate at the same time, they can drive the right rotating rod and the vertical rod to move relative to each other at the same time. When the vertical rods on both sides move relative to each other at the same time, they can respectively drive the connecting block and the clamping members to move relative to each other at the same time. In this way, two workpieces can be clamped on the inside of the two pairs of clamping members. By clamping and processing two workpieces at the same time, the spinning machine can complete more processing tasks in the same time, thereby significantly improving production efficiency.

[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 clamping device for a spinning machine includes a processing table 1, the interior of which is hollow. The characteristic feature is that a clamping mechanism is provided inside the processing table 1. The clamping mechanism includes: two central shafts 101 connected to the inner wall of the processing table 1 via bearings; two rotating rods 102 respectively sleeved on the surfaces of the two central shafts 101; a connecting rod 103, one end of which is connected to both ends of the rotating rod 102 via a rotating shaft; a vertical rod 104 connected to the other end of the connecting rod 103 via a rotating shaft; and a connecting block 105, the bottom part of which... The top of the connecting block 105 is fixedly connected to the top of the vertical rod 104, and the top of the connecting block 105 extends through to the top of the processing table 1; the clamping member 106 is fixedly connected to the top of the connecting block 105; the double-headed electric cylinder 107 is fixedly installed on the inner wall of the processing table 1; both ends of the double-headed electric cylinder 107 are fixedly connected to the left vertical rod 104. Through the cooperation of the clamping mechanism, two workpieces can be clamped and processed at the same time. The linkage clamping mechanism can shorten the workpiece clamping time because multiple workpieces can be clamped in place at one time, reducing the number of repeated clamping and improving the overall production efficiency.

[0021] like Figures 2-3 As shown, the inner wall of the processing table 1 is fixedly connected to a limiting rod 2, and the vertical rods 104 are all slidably connected to the surface of the limiting rod 2. When the rotating rod 102 drives the vertical rods 104 to rotate through the connecting rod 103, the vertical rods 104 can slide on the surface of the limiting rod 2. With the auxiliary guidance of the limiting rod 2, the vertical rods 104 can move in parallel, and can drive the top connecting block 105 and the clamping member 106 to move in parallel, so that the two opposing clamping members 106 can better cooperate to clamp and improve the clamping stability of the workpiece.

[0022] like Figures 2-3 As shown, limiting rings 3 are fitted on the surfaces of both central shafts 101. The limiting rings 3 are located at the top and bottom of the rotating rod 102, respectively. When the rotating rod 102 rotates on the surface of the central shaft 101, in order to prevent the rotating rod 102 from displacing on the surface of the central shaft 101, the limiting rings 3 can be used to limit the rotating rod 102 to the surface of the central shaft 101, so as to prevent the rotating rod 102 from displacing when rotating and affecting the normal operation of the clamping mechanism.

[0023] like Figure 1 As shown, a horizontal groove 4 is provided on the top of the processing table 1, and the connecting blocks 105 are slidably connected to the inside of the horizontal groove 4. When the vertical rod 104 drives the connecting blocks 105 and the clamping member 106 to move, the connecting blocks 105 can move flexibly inside the horizontal groove 4, so that the connecting blocks 105 have sufficient moving space and prevent the connecting blocks 105 from colliding with the processing table 1 and causing motion interference when moving.

[0024] like Figures 1-2 As shown, the inner side of the clamping member 106 is provided with grooves 5, and the inner wall of the grooves 5 is connected with a protective layer. The design of the grooves 5 allows the clamping member 106 to better adapt to the shape of the workpiece and provide a more secure clamping force. The protective layer of the inner wall, such as soft materials like rubber or polyurethane, can effectively reduce the pressure on the surface of the workpiece during the clamping process and prevent scratches, indentations or other damage during the clamping process, thereby protecting the surface of the workpiece from damage, which is especially important for easily damaged workpieces.

[0025] like Figures 1-2 As shown, there are four clamping components 106. The clamping components 106 are arranged in pairs and are positioned opposite each other on the top of the processing table 1. The two pairs of clamping components 106 can clamp and process two workpieces simultaneously through the clamping linkage mechanism. This can complete the clamping and processing of two workpieces at the same time, which greatly improves production efficiency. It is more suitable for batch production, saves the time of clamping and installing workpieces, and accelerates the production cycle.

[0026] The working principle of this utility model is as follows: When the workpiece needs to be fixed on the processing table 1 during processing, the workpiece can be placed between the two pairs of clamping members 106 on the processing table 1. Then, the double-headed electric cylinder 107 is operated and the output rod is pushed to the right. When the output rod of the double-headed cylinder moves to the right, it can simultaneously drive the two pairs of left vertical rods 104 to move to the right. The movement of the left vertical rods 104 to the right can drive the connecting block 105 and the clamping members 106 to move to the right at the same time. When the left vertical rods 104 move to the right, the connecting block 105 and the clamping members 106 can be moved to the right simultaneously. Rod 103 drives rotating rod 102 to rotate on the surface of central shaft 101. When the two rotating rods 102 rotate simultaneously, they can drive the rotating rod 102 on the right and the vertical rod 104 to move relative to each other simultaneously. When the vertical rods 104 on the left and right sides move relative to each other simultaneously, they can drive the connecting block 105 and the clamping member 106 to move relative to each other simultaneously. This allows two workpieces to be clamped on the inside of the two pairs of clamping members 106. By clamping and processing two workpieces simultaneously, the spinning machine can complete more processing tasks in the same time, thereby significantly improving production efficiency.

[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.
