Description

Technical Field

[0001] This utility model relates to the field of workpiece processing and clamping technology, and in particular to a quick clamping mechanism for pressure plate processing. Background Technology

[0002] The press plate is made by impregnating a substrate that has been treated with a solution containing alkoxysilane derivatives and / or their condensates with a thermosetting resin that does not contain halogen flame retardants, heating and drying it to obtain a prepreg blank, stacking several of these prepreg blanks, and stacking copper foil on one or both sides as needed, and then heating and pressing them together.

[0003] The quick clamping mechanism for platen processing is a device specifically designed to quickly and accurately fix the platen onto the processing equipment during platen processing. It can significantly shorten clamping time, reduce auxiliary time during processing, and thus improve overall production efficiency.

[0004] Chinese patent document CN211565186U discloses a quick clamping mechanism for machine tool processing, relating to the field of machine tool processing. It includes a desktop with a movable table inside, and a base plate connected to the bottom of the desktop. An electric push rod is mounted on the top of the base plate. A connecting rod is connected to one end of the movable table, and a threaded post is connected to the bottom of the connecting rod. A bolt is connected to the outside of the threaded post, and a first clamping block is connected to the bottom of the bolt. A motor is mounted on one side of the desktop, and a threaded rod is connected to the output end of the motor. This patent document, through the arrangement of the desktop, movable table, connecting rod, threaded post, bolt, first clamping block, motor, threaded rod, first thread, second thread, movable block, and second clamping block, achieves a clamping mechanism with two directions on the movable table. This allows for flexible handling of machine tool processing in different directions, ensuring the workpiece remains clamped and stationary during processing, thus improving the processing success rate.

[0005] The aforementioned patent literature can be used to process machine tools from different directions, so that the workpiece is held in a fixed position during processing. However, it cannot adjust the height of the workpiece during clamping, which makes it inconvenient for workers to process the pressure plate if the height is too low or too high. Prolonged processing can easily damage the health of the operators and affect the processing efficiency of the pressure plate. Utility Model Content

[0006] The main purpose of this invention is to provide a quick clamping mechanism for pressure plate processing, which can effectively solve the problem of not being able to adjust the height of the workpiece during clamping.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A quick clamping mechanism for platen processing includes a housing. A guide groove (I) communicating with the outside is provided at the center of the front end of the outer surface of the housing. Two guide grooves (II) communicating with the outside are symmetrically provided on the left and right sides of the front end of the outer surface of the housing. Several positioning holes communicating with the outside are spaced apart on the left and right sides of the front end of the outer surface of the housing. A control panel is fixedly installed on the upper right end of the outer surface of the housing. A hydraulic cylinder is fixedly installed at the center of the left side of the bottom wall of the inner cavity of the housing. A pneumatic cylinder is fixedly installed at the center of the upper left side of the outer surface of the housing. A connecting mechanism is fixedly connected to the upper output end of the hydraulic cylinder and the lower output end of the pneumatic cylinder. A transmission mechanism is fixedly connected to the front of the upper connecting mechanism. A pressing mechanism is fixedly connected to the lower part of the transmission mechanism. A bearing mechanism is fixedly connected to the front of the lower connecting mechanism. An electric telescopic rod is fixedly installed at the center of the front part of the inner cavity of the bearing mechanism. A positioning mechanism is fixedly connected to the rear output end of the electric telescopic rod. A base plate is fixedly connected to the upper outer side of the bearing mechanism.

[0009] Preferably, the connecting mechanism includes a clamping rod, and a connecting arm is fixedly connected to the middle of the clamping rod.

[0010] Preferably, the transmission mechanism includes a transmission plate, with T-shaped blocks symmetrically fixedly connected to the rear end of the outer surface of the transmission plate, and the middle of the rear end of the outer surface of the transmission plate and the front end of the outer surface of the connecting arm located at the top are fixedly connected, and the two T-shaped blocks are slidably connected to the inner cavity of the corresponding guide groove.

[0011] Preferably, the pressing mechanism includes a pressing plate, and a plurality of rubber blocks are fixedly connected at intervals to the lower end of the outer surface of the pressing plate, and the upper end of the outer surface of the pressing plate is fixedly connected to the lower end of the outer surface of the transmission plate.

[0012] Preferably, the bearing mechanism includes a bearing frame, and the rear end of the outer surface of the bearing frame is symmetrically provided with guide holes communicating with the outside, and the middle of the rear end of the outer surface of the bearing frame is fixedly connected to the front end of the outer surface of the connecting arm located at the lower part.

[0013] Preferably, the positioning mechanism includes a push plate, with positioning rods fixedly connected symmetrically to the rear end of the outer surface of the push plate, and the middle of the front end of the outer surface of the push plate is fixedly connected to the rear output end of the electric telescopic rod. The outer surface of the push plate is slidably connected to the inner cavity of the bearing frame, and the two positioning rods are slidably connected to the inner cavities of the corresponding guide holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model can connect and transmit the load-bearing mechanism or the transmission mechanism through the connecting mechanism. At the same time, the transmission mechanism can guide the lifting and lowering movement of the pressing mechanism, which improves the practicality of the device. The pressing mechanism can clamp the workpiece. Under the action of the load-bearing mechanism, the electric telescopic rod and the positioning mechanism can be supported. Furthermore, the positioning mechanism can easily lock the position of the load-bearing mechanism, which improves the practicality and versatility of the device.

[0016] 2. After the base plate is adjusted to the required height, although the hydraulic cylinder itself has a self-locking capability and can lock the position of the bearing frame and the base plate, since the workpiece placed on the upper part of the base plate needs to be pressed down and clamped by the lower pressure plate, the electric telescopic rod is driven to push the two positioning rods into the inner cavity of the two positioning holes that are aligned with the base plate. Thus, the two positioning rods can further support the base plate, preventing the base plate from shaking when the lower pressure plate presses down on the workpiece placed on the upper part of the base plate, thereby improving the practicality and universality of the device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1As shown, the quick clamping mechanism for platen processing includes a housing 1. A guide groove 2 communicating with the outside is provided at the center of the front end of the outer surface of the housing 1. Two guide grooves 3 communicating with the outside are symmetrically provided on the left and right sides of the front end of the outer surface of the housing 1. Several positioning holes 4 communicating with the outside are spaced apart on the left and right sides of the front end of the outer surface of the housing 1. A control panel 5 is fixedly installed on the upper right side of the outer surface of the housing 1. A hydraulic cylinder 6 is fixedly installed at the center of the left side of the bottom wall of the inner cavity of the housing 1. A pneumatic cylinder 7 is fixedly installed at the center of the upper left side of the outer surface of the housing 1. A connecting mechanism 8 is fixedly connected to both the upper output end of the hydraulic cylinder 6 and the lower output end of the pneumatic cylinder 7, enabling connection and transmission to the load-bearing mechanism 11 or the transmission mechanism 9. The upper connecting mechanism 8 is fixedly connected to the front of the transmission mechanism 9, which can guide the lifting and lowering movement of the pressing mechanism 10. The lower part of the transmission mechanism 9 is fixedly connected to the pressing mechanism 10, which can clamp the workpiece. The lower connecting mechanism 8 is fixedly connected to the front of the bearing mechanism 8, which can support the electric telescopic rod 12 and the positioning mechanism 13. The electric telescopic rod 12 is installed and fixedly fixed in the middle of the front part of the inner cavity of the bearing mechanism 11. The positioning mechanism 13 is fixedly connected to the rear output end of the electric telescopic rod 12, which can lock the position of the bearing mechanism 11. The upper side of the bearing mechanism 11 is fixedly connected to the base plate 14.

[0024] To achieve the purpose of connecting and transmitting power to the load-bearing mechanism 11 or the transmission mechanism 9, refer to... Figure 2 The connecting mechanism 8 includes a clamping rod 81, which can drive the connecting arm 82 to move up and down. The connecting arm 82 is fixedly connected to the middle of the clamping rod 81, which can drive the bearing frame 111 or the transmission plate 91 to move up and down.

[0025] To guide the lifting and lowering motion of the pressing mechanism 10, refer to... Figure 2 The transmission mechanism 9 includes a transmission plate 91. T-shaped blocks 92 are symmetrically fixedly connected to the rear end of the outer surface of the transmission plate 91. These blocks can slide within the corresponding guide groove 3 to make the movement of the transmission plate 91 more stable. The middle of the rear end of the outer surface of the transmission plate 91 is fixedly connected to the front end of the outer surface of the connecting arm 82 located at the top. The two T-shaped blocks 92 are slidably connected to the corresponding guide groove 3.

[0026] To achieve the purpose of clamping the workpiece, refer to... Figure 2 The pressing mechanism 10 includes a pressing plate 101. Several rubber blocks 102 are fixedly connected at intervals on the lower end of the outer surface of the pressing plate 101. This can make the workpiece clamping more stable and avoid the phenomenon of sliding and displacement during processing. The upper end of the outer surface of the pressing plate 101 is fixedly connected to the lower end of the outer surface of the transmission plate 91.

[0027] To achieve the purpose of supporting the electric telescopic pole 12 and the positioning mechanism 13, see [reference] Figure 3 The supporting mechanism 11 includes a supporting frame 111. The outer surface of the supporting frame 111 has symmetrical guide holes 112 at the rear end that communicate with the outside, which can guide the back and forth sliding of the two positioning rods 132. The middle of the rear end of the outer surface of the supporting frame 111 is fixedly connected to the front end of the outer surface of the connecting arm 82 located at the bottom.

[0028] For the purpose of facilitating the locking of the position of the bearing mechanism 11, please refer to... Figure 4 The positioning mechanism 13 includes a push plate 131. Positioning rods 132 are symmetrically fixedly connected to the rear end of the outer surface of the push plate 131. The middle part of the front end of the outer surface of the push plate 131 is fixedly connected to the rear output end of the electric telescopic rod 12. The outer surface of the push plate 131 is slidably connected to the inner cavity of the bearing frame 111. The two positioning rods 132 are slidably connected to the inner cavity of the corresponding guide hole 112.

[0029] When the base plate 14 is adjusted to the required height by the hydraulic cylinder 6, the electric telescopic rod 12 is driven to push the push plate 131 to slide backward along the inner cavity of the support frame 111, so that it pushes the two positioning rods 132 through the inner cavity of the guide hole 112 and into the inner cavity of the positioning hole 4 that is aligned with it, thereby locking the position of the base plate 14.

[0030] It should be noted that in this utility model, the hydraulic cylinder 6 is model SLD30×50, the electric telescopic rod 12 is model Jetino electric push rod fy011g, and the cylinder 7 is model MDBB32-50Z-M9BW. The specific installation methods, oil circuit connection methods, circuit connection methods, and control methods of the hydraulic cylinder 6, cylinder 7, and electric telescopic rod 12 are all conventional designs, and this utility model will not elaborate on them in detail.

[0031] The working principle of this utility model is as follows: First, the workpiece to be processed is placed on the upper part of the base plate 14. Then, according to the height required by the operator, the hydraulic cylinder 6 is driven to drive the connecting arm 82 located at the lower part to slide up and down in the inner cavity of the guide groove 2 3. When the base plate 14 is adjusted to the required height, the electric telescopic rod 12 is driven to push the push plate 131 to slide backward along the inner cavity of the bearing frame 111 until the two positioning rods 132 are fully inserted into the inner cavities of the two positioning holes 4 that are aligned with the height. At this time, the driving cylinder 7 pushes the connecting arm 82 located at the upper part to start moving downward. During this period, the two T-shaped blocks 92 slide in the inner cavity of the corresponding guide groove 2 3, thereby driving the transmission plate 91 and the lower pressure plate 101 to descend stably until the lower pressure plate 101 stably clamps the workpiece placed on the upper end of the base plate 14.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
