Description

Technical Field

[0001] This utility model relates to the field of template cylinder technology, and more specifically, to a multi-position template cylinder. Background Technology

[0002] Template cylinders are widely used in woodworking machinery, packaging machinery, and automated equipment for clamping, positioning, or pushing templates. Existing template cylinders are typically fixed directly to the equipment frame with bolts, their installation position determined by the location of the bolt holes. When processing templates of different sizes, it is necessary to re-drill and tap holes in the equipment frame, a cumbersome and time-consuming adjustment process with extremely poor flexibility, failing to meet the demands of modern flexible production and rapid changeover.

[0003] In the existing technology, some cylinders are adjusted by opening long holes in the mounting plate. However, this method has low positioning accuracy and poor locking reliability. Under repeated impact loads, the cylinder is prone to loosening, which affects the stability of the cylinder's support for the template. Utility Model Content

[0004] This invention provides a multi-position template cylinder, which solves the technical problems in the prior art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A multi-position template cylinder includes a cylinder body and a base. The cylinder body is disposed at the top of the base. A piston is slidably disposed inside the cylinder body. A push rod is fixedly connected to one side of the piston. The end of the push rod extends out of the outer side of the cylinder body and is fixedly connected to a push block. A lead screw is rotatably connected inside the base. A threaded sleeve is threaded onto the surface of the lead screw. One end of the lead screw extends out of the outer side of the base and is connected to a first knob. A through slot is provided at the top of the base. A connecting rod is connected to the top of the threaded sleeve. The connecting rod extends out of the outer side of the base through the through slot and is connected to a set of brackets. The bottom end of the cylinder body is fixedly connected to the brackets by screws. A fastening assembly is provided between the brackets and the base. The fastening assembly includes friction strips disposed on both sides of the outer wall of the base, threaded sleeves fixedly connected to both sides of the bracket, and a screw threadedly connected to the inside of the threaded sleeves. The inner side of the screw faces the friction strips and is connected to a friction plate, and the outer side of the screw is connected to a second knob.

[0006] Furthermore, slide rails are provided on both sides of the top of the base, and two sets of sliders are provided at the bottom of the bracket, with the sliders slidably connected to the slide rails.

[0007] Furthermore, the base has scale lines distributed on its side wall, and the bottom of the bracket is connected to a pointer that points to the scale lines.

[0008] Furthermore, a spring is provided inside the cylinder body, and the spring is nested on the surface of the push rod, with its two ends respectively abutting against the inner wall of the cylinder body and the piston.

[0009] Furthermore, the top block is made of aluminum alloy, and the edges of the top block have a rounded corner structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the setting of the lead screw, lead sleeve, first knob and other structures, the position of the cylinder body on the base can be flexibly adjusted. When the top block at the front end of the top rod is connected to the template, the initial position of the top block can flexibly adapt to templates of different sizes. The positioning accuracy of the cylinder body after adjustment is high, and the cylinder body can be stably locked and fixed in the adjusted position, so that the cylinder body is not easy to loosen under load, thereby ensuring its stability in supporting the template.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-5 A multi-position template cylinder includes a cylinder body 1 and a base 2. The cylinder body 1 is located at the top of the base 2. A piston 3 is slidably disposed inside the cylinder body 1. A push rod 4 is fixedly connected to one side of the piston 3. The end of the push rod 4 extends out of the outside of the cylinder body 1 and is fixedly connected to a top block 5. The top block 5 is connected to one side of the template. Air holes for connecting pneumatic valves are provided at both ends of the top of the cylinder body 1. Through the pneumatic valves, air can be charged or released at the front and rear ends inside the cylinder body 1, thereby changing the air pressure on both sides of the piston 3. This allows the piston 3 to slide back and forth inside the cylinder body 1 under the action of the air pressure difference, which in turn allows the push rod 4 to drive the top block 5 to move back and forth. A lead screw 6 is rotatably connected inside the base 2. A threaded sleeve 7 is threaded onto the surface of the lead screw 6. One end of the lead screw 6 extends out of the outside of the base 2 and is connected to a first knob 8. By holding the first knob 8, the template can be controlled. The lead screw 6 rotates. Due to the meshing relationship between the lead screw 6 and the sleeve 7, when the lead screw 6 rotates relative to the sleeve 7, the sleeve 7 can move horizontally along its surface under the driving action of the lead screw 6. The top of the base 2 is provided with a through slot 9. The top of the sleeve 7 is connected to a connecting rod 10. The connecting rod 10 extends out of the outside of the base 2 through the through slot 9 and is connected to a set of brackets 11. The bottom of the cylinder body 1 is fixedly connected to the brackets 11 by screws. When the sleeve 7 moves horizontally under the driving action of the lead screw 6, the sleeve 7 will drive the cylinder body 1 to move horizontally back and forth through the through slot 9 and the brackets 11, thereby adjusting the position of the cylinder body 1. In addition, a fastening component is provided between the bracket 11 and the base 2. The fastening component can lock and fix the bracket 11 and the base 2, so that the cylinder body 1 can be stably maintained in the adjusted position and is not easy to displace.

[0018] After fixing the base 2 in the mounting position, the user can control the lead screw 6 to rotate by holding the first knob 8, causing the threaded sleeve 7 to move horizontally back and forth under the drive of the lead screw 6. During this process, the threaded sleeve 7 will drive the cylinder body 1 at the top of the base 2 to move horizontally through the through slot 9 and the bracket 11, thus allowing for flexible adjustment of the front end position of the cylinder body 1. After adjustment, a threaded locking effect will be generated between the lead screw 6 and the threaded sleeve 7, restricting relative movement between them. In addition, the fastening assembly can lock and fix the bracket 11 and the base 2. Therefore, under the threaded locking effect generated by the lead screw 6 and the threaded sleeve 7 and the fixing effect generated by the fastening assembly, This structure allows the cylinder body 1 to be stably maintained in the adjusted position, preventing it from shifting under external force during operation. Thus, through the screw 6, screw sleeve 7, and first knob 8, the position of the cylinder body 1 on the base 2 can be flexibly adjusted. When the top block 5 at the front end of the top rod 4 is connected to the template, the initial position of the top block 5 can flexibly adapt to templates of different sizes. The adjusted cylinder body 1 has high positioning accuracy and can be stably locked and fixed in the adjusted position, making it less prone to loosening under load, thereby ensuring its stability in supporting the template.

[0019] For further details, please refer to Figure 1-5 The fastening assembly includes friction strips 12 disposed on both sides of the outer wall of the base 2, threaded sleeves 13 fixedly connected to both sides of the bracket 11, and a screw 14 threadedly connected to the inside of the threaded sleeves 13. The inner side of the screw 14 faces the friction strips 12 and is connected to a friction plate 15. A second knob 16 is connected to the outer side of the screw 14. When the user holds the second knob 16, the screw 14 can be rotated. While rotating, the screw 14 will move towards or away from the base 2 under the driving action of the threaded sleeves 13. When the screw 14 is controlled to approach the base 2, the friction plate 15 on the inner side of the screw 14 will come into close contact with the friction strips 12 on the outer wall of the base 2, thereby generating a large frictional resistance between the friction plate 15 and the friction strips 12. Under this action, the relative sliding between the bracket 11 and the base 2 can be restricted, so that the two can be locked and fixed.

[0020] For further details, please refer to Figure 1-5 The top two sides of the base 2 are respectively provided with slide rails 17, and the bottom of the bracket 11 is provided with two sets of sliders 18. The sliders 18 are slidably connected to the slide rails 17. When the control bracket 11 drives the cylinder body 1 to move back and forth, the sliders 18 can always keep sliding horizontally along the direction of the slide rails 17. At this time, the slide rails 17 and sliders 18 can guide the movement of the bracket 11, avoiding the cylinder body 1 from being misaligned or tilted during the movement, and further ensuring the accuracy of the positioning of the cylinder body 1.

[0021] For further details, please refer to Figure 1-5 The base 2 has scale lines 19 distributed on its side wall. The bottom of the bracket 11 is connected to a pointer 20 that points to the scale lines 19. During the adjustment of the position of the cylinder body 1, the bracket 11 will move the cylinder body 1 along the direction of the base 2. At this time, the operator can accurately judge the distance moved by the cylinder body 1 by observing the reading of the pointer 20 pointing to the scale line 19, so as to facilitate the precise adjustment of the position of the cylinder body 1.

[0022] For further details, please refer to Figure 1-5 A spring 21 is installed inside the cylinder body 1. The spring 21 is nested on the surface of the push rod 4, and its two ends abut against the inner wall of the cylinder body 1 and the piston 3, respectively. When the piston 3 moves forward under the action of air pressure and causes the push rod 4 to extend forward, the spring 21 will be compressed and generate a backward elastic force on the piston 3. This elastic force can buffer the piston 3 and prevent the piston 3 from impacting the inner wall of the cylinder body 1 and causing damage. Moreover, the elastic force generated by the spring 21 can assist the piston 3 to move backward for reset. When the piston 3 moves a long distance, it can ensure that the piston 3 is not prone to delay or jamming during the reset process.

[0023] For further details, please refer to Figure 1-5 The top block 5 is made of aluminum alloy and has a hard oxide layer on its surface, which can effectively improve the wear resistance of the top block 5. The edges of the top block 5 are rounded, so it is not easy to damage the template when it extends quickly.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
