Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated assembly technology, specifically a bottom lifting reaction support mechanism. Background Technology
[0002] During pressing, especially when the pressing force is large, a rigid reaction support is required at the bottom to directly transfer the pressing force to the equipment and protect the pressed product from damage. This is widely used in automated pressing equipment, and there are many forms of reaction support, including fixed ones and laterally displaced ones (in conjunction with pneumatic or servo slides), etc.
[0003] The reaction support structure is not complicated and the principle is simple. However, some existing reaction supports cannot be used in specific situations. Fixed types cannot avoid interference when pressing in different positions multiple times; lateral displacement types cannot move when the surrounding space is limited, and there will be interference. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a bottom lifting reaction support mechanism, which can effectively solve the problems in the prior art.
[0005] The technical solution adopted by this utility model is as follows: a bottom lifting reaction force support mechanism, including a fixed base and a support plate located above the fixed base. A guide bushing is fixedly installed at one end of the fixed base near the support plate. A fixed plate is fixedly installed at the end of the guide bushing away from the fixed base. A guide rail is fixedly installed at the center of the end of the fixed plate away from the guide bushing. A lifting cylinder is fixedly installed on the side of the fixed plate away from the support plate. A guide shaft is fixedly installed at the movable end of the lifting cylinder. A shaft step is fixedly installed on the outer surface of the end of the guide shaft near the support plate. A transverse movement cylinder is fixedly installed at the end of the fixed plate near the support plate. A sliding block is fixedly installed at the movable end of the transverse movement cylinder. A slot is opened at the end of the sliding block near the guide shaft.
[0006] Preferably, the lateral movement cylinder is located above the lifting cylinder, and the lateral movement cylinder and the lifting cylinder are vertically distributed on the device.
[0007] The above technical solution allows for structural avoidance by adjusting the vertical position of the lifting cylinder, freeing up space for other pressing processes. The lateral displacement of the transverse cylinder provides a reaction force function, offering reaction force support during pressing.
[0008] Preferably, the guide shaft is installed through the guide bushing, and the guide shaft and the guide bushing are slidably connected.
[0009] The above technical solution, through the sliding connection design between the guide shaft and the guide bushing, can not only achieve smooth up-and-down sliding of the guide shaft, but also ensure verticality.
[0010] Preferably, the sliding block is adapted to the guide rail, and the sliding block and the guide rail are slidably connected.
[0011] Through the above technical solution, by adapting the sliding block to the guide rail and making a sliding connection between the sliding block and the guide rail, a reaction force support is provided when press-fitting is required. The transverse cylinder is activated, and the moving end of the transverse cylinder drives the sliding block to slide and change position within the guide rail until it moves below the shaft step, thus providing a press-fitting reaction force.
[0012] Preferably, the cross-section of the slot is C-shaped, the diameter of the slot is the same as the diameter of the guide shaft, and the diameter of the shaft step is greater than the diameter of the guide shaft.
[0013] The above technical solution, by setting the cross-section of the slot to be "C" shaped, facilitates close contact with the guide shaft. The diameter of the slot is the same as the diameter of the guide shaft, and the diameter of the shaft step is larger than the diameter of the guide shaft. When the slot of the sliding block contacts the guide shaft, the shaft step will contact the upper surface of the sliding block, transferring the reaction force of the support plate to the shaft step on the guide shaft, and then to the sliding block, thus realizing the function of reaction force support.
[0014] Preferably, the guide shaft has a guide groove on the side near the guide bushing, and a limit rod is provided on the outer side of the guide bushing. The inner diameter of the guide groove is the same as the outer diameter of the limit rod, and the guide groove and the limit rod are slidably connected.
[0015] Through the above technical solution, the guide groove and the limiting rod are slidably connected, which can realize the secondary guiding effect on the guide shaft and further ensure the perpendicularity of the guide shaft.
[0016] Compared with the prior art, this utility model provides a bottom lifting reaction force support mechanism, which has the following beneficial effects: 1. The bottom lifting reaction support mechanism can achieve structural avoidance by setting the vertical displacement of the lifting cylinder, freeing up space for other pressing processes. The reaction function is achieved by the horizontal displacement of the transverse cylinder, providing reaction support during pressing. Since the transverse cylinder and the lifting cylinder are vertically distributed on the device, there is no need to occupy extra horizontal or vertical redundant space, and two core drive components can be accommodated in a limited device volume at the same time. 2. The bottom lifting reaction force support mechanism has a "C"-shaped cross-section for the slot, which facilitates close contact with the guide shaft. The diameter of the slot is the same as that of the guide shaft, and the diameter of the shaft step is larger than that of the guide shaft. When the slot of the sliding block contacts the guide shaft, the shaft step will contact the upper surface of the sliding block, transferring the reaction force of the support plate to the shaft step on the guide shaft, and then to the sliding block, thus realizing the function of reaction force support.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: As Figure 1-5 As shown, the present invention provides a bottom lifting reaction force support mechanism, including a fixed base 1 and a support plate 13 located above the fixed base 1. A guide bushing 2 is fixedly installed at one end of the fixed base 1 near the support plate 13. A fixed plate 3 is fixedly installed at the other end of the guide bushing 2 away from the fixed base 1. A guide rail 4 is fixedly installed at the center of the other end of the fixed plate 3 away from the guide bushing 2. A lifting cylinder 5 is fixedly installed on the other side of the fixed plate 3 away from the support plate 13. A guide shaft 6 is fixedly installed at the movable end of the lifting cylinder 5. A shaft step 7 is fixedly installed on the outer surface of the guide shaft 6 near the support plate 13. A transverse cylinder 10 is fixedly installed at the other end of the fixed plate 3 near the support plate 13. A sliding block 11 is fixedly installed at the movable end of the transverse cylinder 10. A slot 12 is provided at the other end of the sliding block 11 near the guide shaft 6.
[0021] Specifically, the transverse cylinder 10 is located above the lifting cylinder 5, and the transverse cylinder 10 and the lifting cylinder 5 are vertically distributed on the device. The advantage is that by setting the vertical displacement of the lifting cylinder 5, structural avoidance can be achieved, freeing up space for other pressing processes. By lateral displacement of the transverse cylinder 10, a reaction force function is achieved, providing reaction force support during pressing.
[0022] Specifically, the guide shaft 6 is installed through the guide bushing 2, and the guide shaft 6 and the guide bushing 2 are slidably connected. The advantage is that the slidable connection between the guide shaft 6 and the guide bushing 2 allows the guide shaft 6 to slide smoothly up and down while ensuring verticality.
[0023] Specifically, the sliding block 11 is adapted to the guide rail 4, and the sliding block 11 and the guide rail 4 are slidably connected. The advantage is that by adapting the sliding block 11 to the guide rail 4 and making the sliding block 11 and the guide rail 4 slidably connected, a reaction force support is provided when press-fitting is required. The transverse cylinder 10 is activated, and the moving end of the transverse cylinder 10 drives the sliding block 11 to slide and change position within the guide rail 4 until it moves below the shaft step 7, thus providing the press-fitting reaction force.
[0024] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.
[0025] Specifically, the slot 12 has a C-shaped cross-section, with the same diameter as the guide shaft 6 and the diameter of the shaft step 7 being larger than that of the guide shaft 6. The advantage is that by setting the slot 12 to a C-shape, it facilitates close contact with the guide shaft 6. Furthermore, because the diameter of the slot 12 is the same as the guide shaft 6, and the diameter of the shaft step 7 is larger than that of the guide shaft 6, when the slot 12 of the sliding block 11 contacts the guide shaft 6, the shaft step 7 will contact the upper surface of the sliding block 11, transferring the reaction force of the support plate 13 to the shaft step 7 on the guide shaft 6, and then to the sliding block 11, thus achieving the function of reaction force support.
[0026] Specifically, a guide groove 8 is provided on the side of the guide shaft 6 near the guide bushing 2, and a limit rod 9 is provided on the outer side of the guide bushing 2. The inner diameter of the guide groove 8 is the same as the outer diameter of the limit rod 9, and the guide groove 8 and the limit rod 9 are slidably connected. The advantage is that the slidable connection between the guide groove 8 and the limit rod 9 can achieve a secondary guiding effect on the guide shaft 6, further ensuring the perpendicularity of the guide shaft 6.
[0027] Working Principle: During use, the vertical displacement of the lifting cylinder 5 allows for structural clearance, freeing up space for other pressing processes. The lateral displacement of the transverse cylinder 10 provides a reaction force, offering support during pressing. The sliding connection between the guide shaft 6 and the guide bushing 2 ensures smooth vertical movement of the guide shaft 6 while maintaining its verticality. Furthermore, the sliding connection between the guide groove 8 and the limit rod 9 provides secondary guidance for the guide shaft 6, further ensuring its verticality. The sliding block 11, which is compatible with the guide rail 4 and slidably connected to it, provides support during pressing when needed. Force support is applied, and the transverse cylinder 10 is activated. The movable end of the transverse cylinder 10 drives the sliding block 11 to slide and change position within the guide rail 4 until it moves below the shaft step 7. Press-fit reaction force is applied. By setting the groove 12 with a "C"-shaped cross-section, it can easily make close contact with the guide shaft 6. The diameter of the groove 12 is the same as the diameter of the guide shaft 6, and the diameter of the shaft step 7 is larger than the diameter of the guide shaft 6. When the groove 12 of the sliding block 11 contacts the guide shaft 6, the shaft step 7 will contact the upper surface of the sliding block 11, transferring the reaction force of the support plate 13 to the shaft step 7 on the guide shaft 6, and then to the sliding block 11, thus realizing the function of reaction force support.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
