It integrates multiple stations on one fixture, so that one clamping can complete the processing of multiple workpieces at the same time, greatly improving production efficiency. At the same time, the multi-station fixture also has the characteristics of high precision, high stability and high reliability, which can ensure the accuracy and consistency of the processing process and improve product quality. With the continuous development of automation technology, multi-station processing automatic fixtures have gradually realized automated control. Through preset programs and sensors and other devices, the fixture can automatically complete operations such as clamping, positioning, processing and unloading of workpieces, reducing manual intervention, reducing operating errors, and improving production efficiency and safety.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the prior art, most of the clamps and the fixing plate 110 are fixed by manual bolts. Therefore, when disassembling, it is necessary to manually disassemble, which is cumbersome and time-consuming. Please refer to Figure 1-Figure 7 A multi-station processing automatic fixture includes a fixed disk 110 and a clamping device 210. A power column 180 is fixedly installed in the middle of the fixed disk 110. A transmission pipe 190 is inserted into the side of the power column 180. The end of the transmission pipe 190 is connected to a cylinder 170. A connecting rod 160 is fixedly connected to the side of the cylinder 170. The connecting rod 160 is inserted in the middle of a connecting tube 230. A buffer assembly 450 is installed in the middle of the connecting tube 230.

[0027] A clamping device 210 is installed on the side of the connecting cylinder 230, and the clamping device 210 is fixedly installed with a connecting plate 150 through a fixing bolt 220. The side of the connecting plate 150 is fixedly connected to the limiting plate 140, and a locking bolt 250 is fixedly connected to the bottom of the limiting plate 140. A locking assembly 260 is installed on the side of the locking bolt 250. A sliding groove 130 is opened in the middle of the fixed disk 110, and the limiting plate 140 slides in the middle of the sliding groove 130. The end of the sliding groove 130 is connected to the fixing groove 120, and the side of the fixing groove 120 is connected to the locking groove 240. The locking bolt 250 is locked and connected with the fixing groove 120, and the locking assembly 260 is locked and connected with the locking groove 240.

[0028] When the clamp is in use, the locking assembly 260 is set so that when the limit plate 140 is locked and connected, it can be automatically locked without manual fixation, which saves a lot of time for the staff and significantly improves work efficiency. During the locking process of the locking bolt 250, in order to avoid the impact force of the locking bolt 250 on the fixing groove 120 as much as possible, the buffer assembly 450 is set to reduce the thrust of the connecting rod 160 and protect the fixing groove 120.

[0029] When the thrust is large, the connecting rod 160 will push the contact block 310, and the contact block 310 will push the stabilizing block 430. Through the setting of the rotating shaft 410 and the rotating shaft 440, when the stabilizing block 430 is pushed, the rotating rod 420 will rotate, and then it will push the limiting sleeve 380 to squeeze the limiting spring 390, thereby forming a buffer. During the pushing process of the contact block 310, the buffer rod 360 will squeeze the buffer cylinder 340. Since the buffer cylinder 340 is a rubber cylinder, a buffering effect will be formed to protect it.

[0030] In this embodiment: through the arrangement of the locking bolt 250 and the locking assembly 260, when the limit plate 140 is locked and fixed, when the fixing plate 110 is pushed into the fixing groove 120 by the cylinder 170, the extrusion spring 290 on the side of the locking assembly 260 will release the elastic force, and then push the slider 300 to engage with the locking groove 240 to complete the automatic locking of the limit plate 140. When disassembly is required, the cylinder 170 is used to pull back the connecting plate 150. During the pulling process, since the groove of the locking groove 240 and the end of the slider 300 are both chamfered, the slider 300 will be smoothly squeezed into the installation groove 270 when pulled back, so that it can be disassembled. Through the cooperation between a series of structures, the clamp is easy to disassemble and install, thereby greatly improving the work efficiency of the staff.

[0031] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that when the cylinder 170 pushes the connecting plate 150 to move, when the limit plate 140 is engaged with the fixing plate 110, the engaging bolt 250 will impact the fixing plate 110. If no buffer protection is performed, the fixing plate 110 is likely to be damaged during long-term use. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The locking assembly 260 includes a mounting groove 270 opened in the middle of the locking bolt 250, a fixing plate 280 is fixedly installed on the side of the mounting groove 270, and an extrusion spring 290 is installed in the middle of the mounting groove 270. One end of the extrusion spring 290 is fixedly connected to the fixing plate 280, and the other end of the extrusion spring 290 is fixedly connected to the slider 300.

[0032] The buffer assembly 450 includes a contact block 310 fixedly installed in the middle of the connecting cylinder 230, a buffer rod 360 is fixedly connected to the bottom of the contact block 310, the buffer rod 360 is inserted in the middle of the buffer cylinder 340, the buffer cylinder 340 is fixedly installed with the fixing plate 330 by the mounting bolt 350, a mounting block 320 is fixedly installed at the bottom of the fixing plate 330, and a mounting rod 370 is fixedly connected to the side of the mounting block 320.

[0033] A limiting sleeve 380 is sleeved on the middle part of the mounting rod 370, and a limiting spring 390 is sleeved on the side part of the mounting rod 370. One end of the limiting spring 390 is fixedly connected to the limiting sleeve 380, and the other end of the limiting spring 390 is fixedly connected to the mounting block 320. A reinforcement block 400 is fixedly installed on the end of the limiting sleeve 380, a rotating shaft 410 is fixedly installed in the middle part of the reinforcement block 400, and a rotating rod 420 is hinged on the side of the rotating shaft 410. A stabilizing block 430 is fixedly connected to the middle part of the contact block 310, a rotating shaft 440 is fixedly installed in the middle part of the stabilizing block 430, and the side of the rotating shaft 440 is hinged to the rotating rod 420.

[0034] In this embodiment: when the cylinder 170 pushes the connecting plate 150, the limiting plate 140 will be pushed, and then will be engaged and connected with the fixing groove 120. When engaged, the engaging bolt 250 will automatically engage with the fixing plate 110. If the fixing plate 110 is not protected, then after long-term use, the fixing groove 120 in the middle of the fixing plate 110 may be damaged due to multiple impacts of the engaging bolt 250. By setting the buffer assembly 450, when the engaging bolt 250 is engaged with the fixing groove 120, the limiting of the buffer assembly 450 will reduce the impact force of the connecting rod 160, thereby protecting the fixing groove 120 and greatly improving the service life of the fixing plate 110.
