Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture processing technology, and in particular to a positioning fixture for processing wooden furniture. Background Technology
[0002] A search revealed that application number 202221901701.9 discloses a positioning fixture for processing wooden furniture, including a first mounting plate and a second mounting plate. A first support plate, a second support plate, and two bidirectional lead screws are provided between the first mounting plate and the second mounting plate. The two ends of the bidirectional lead screws pass through the first mounting plate and the second mounting plate respectively. The two ends of the bidirectional lead screws are rotatably connected to the first mounting plate and the second mounting plate respectively through a first bearing. A synchronous drive mechanism that cooperates with the two bidirectional lead screws is provided on one side of the first mounting plate.
[0003] The positioning fixture for processing wooden furniture in this patent application involves rotating a one-way lead screw to move a second fixed plate. This second fixed plate moves synchronously via a first movable plate, and together with two third fixed plates, clamps and secures the furniture. However, in this configuration, the one-way lead screw is located at the bottom center of the overall structure, making it inconvenient for manual operation. Furthermore, when the device moves the first and second movable plates closer together, the end of the positioning plate furthest from the first movable plate tends to extend outside the device, affecting its overall aesthetics and hindering the movement of workers around it. Therefore, we propose a positioning fixture for processing wooden furniture. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide a positioning fixture for processing wooden furniture.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a positioning fixture for processing wooden furniture includes a frame. Sliding movable support plates are symmetrically connected to the front and rear sides of the frame. An adjustment mechanism is provided in the middle of the frame's inner cavity to drive the two sliding support plates to move back and forth. The adjustment mechanism includes a longitudinal bidirectional threaded rod rotatably connected to the middle of the frame's inner cavity and two adjusting threaded sleeves fixedly fitted into the bottom of the middle of the two sliding support plates. Adjusting grooves are provided on the top surfaces of both sliding support plates. Positioning mechanisms are provided inside each adjusting groove. The positioning mechanisms include a transverse bidirectional threaded rod rotatably connected to the inside of the adjusting groove, two adjusting nut blocks slidably connected to the inside of the adjusting groove, and two fixing plates symmetrically fixedly installed on the top of the two adjusting nut blocks. A driving mechanism is provided on the left side of the frame's inner cavity to drive the two transverse bidirectional threaded rods to rotate. The driving mechanism includes two adjusting worm gears rotatably connected to the lower left side of the two adjusting grooves and a hexagonal sliding rod rotatably connected to the left side of the frame's inner cavity.
[0006] Furthermore, the longitudinal bidirectional threaded rod has threads in opposite directions at its front and rear ends, which are connected to the internal threads of two adjusting threaded sleeves.
[0007] Furthermore, an adjustment motor is fixedly installed in the middle of the front wall of the equipment frame.
[0008] Furthermore, the front end of the longitudinal bidirectional threaded rod penetrates the front wall of the inner cavity of the equipment frame and is fixedly installed with the output end of the regulating motor.
[0009] Furthermore, the left and right side walls of the inner cavity of the equipment frame are symmetrically provided with limiting grooves.
[0010] Furthermore, two horizontally positioned limiting slide rods are fixedly connected inside the two limiting slide grooves.
[0011] Furthermore, the outer walls of the two limiting slide rods are slidably connected to four limiting sliders that are fixedly connected to the left and right ends of the two movable support cross plates.
[0012] Furthermore, the left and right ends of the transverse bidirectional threaded rod are respectively provided with threads in opposite directions and are connected to the internal threads of the two adjusting nut blocks.
[0013] Furthermore, two rubber pads are fixedly installed on the side of the two fixing plates that are close to each other.
[0014] Furthermore, two adjusting worm wheels that mesh with the outer walls of the two adjusting worms are fixedly installed on the left outer walls of the two transverse bidirectional threaded rods.
[0015] Furthermore, the two adjusting worm gears have two hexagonal grooves that fit the outer wall of the hexagonal slide rod.
[0016] Furthermore, the outer wall surface of the hexagonal slide rod is slidably connected to the inside of two hexagonal grooves.
[0017] Furthermore, the front end of the hexagonal slide bar extends through the front wall of the inner cavity of the equipment frame to the outside and is fixedly installed with an adjusting handwheel.
[0018] This utility model provides a positioning fixture for processing wooden furniture. It has the following beneficial effects:
[0019] 1. This positioning fixture for processing wooden furniture comprises an adjustment mechanism, a positioning mechanism, and a drive mechanism. During use, based on the length of the furniture to be processed, the output of the adjusting motor drives the longitudinal bidirectional threaded rod to rotate. This forces two adjusting threaded sleeves, threaded to both ends of the longitudinal bidirectional threaded rod, to move two movable support plates closer together or further apart to adjust their position. This ensures the distance between the two movable support plates matches the length of the furniture. The furniture is then placed at the center of the top surface of the two movable support plates. Rotating the adjusting handwheel drives the hexagonal slide rod to rotate, which in turn drives two adjusting worm gears slidably connected to its surface to move synchronously. The rotation forces the two adjusting worm gears, which mesh with the two adjusting worms, to drive the two transverse double-threaded rods to rotate synchronously. This, in turn, forces the four fixing plates, which are threaded to the ends of the two transverse double-threaded rods, to move closer together and clamp and fix the furniture. The above operation is simple and practical, and the structure is reasonable and compact. This device enables convenient furniture fixing. Since the adjusting handwheel is located at the front end of the outer side of the device frame, it is easy for the staff to operate, improving the ease of use of the device. Furthermore, no parts extend to the outside of the device frame during use, improving the overall aesthetics of the device and avoiding obstructing the movement of staff around it.
[0020] 2. This positioning fixture for processing wooden furniture, by setting limit sliders and limit rods, the four limit sliders and the two limit rods are slidably connected to the outer wall surface to form a limiting and guiding effect on the left and right ends of the two movable support horizontal plates, so that the two movable support horizontal plates can be stably placed inside the equipment frame, thereby improving the stability of the equipment structure.

[0027] A positioning fixture for processing wooden furniture, such as Figure 1-3As shown, the device includes a frame 10. Sliding movable support plates 11 are symmetrically connected to the front and rear sides of the frame 10. An adjustment mechanism is provided in the middle of the inner cavity of the frame 10 to drive the two movable support plates 11 to move back and forth. The adjustment mechanism includes a longitudinal bidirectional threaded rod 12 rotatably connected to the middle of the inner cavity of the frame 10, and two adjusting threaded sleeves 13 fixedly fitted into the bottom middle of the two movable support plates 11. The front and rear ends of the longitudinal bidirectional threaded rod 12 are respectively provided with threads in opposite directions and are threadedly connected to the inside of the two adjusting threaded sleeves 13. A fixed mounting is installed in the middle of the front wall of the frame 10. The equipment frame 10 is equipped with an adjusting motor 14. The front end of a longitudinal bidirectional threaded rod 12 penetrates the front wall of the inner cavity of the equipment frame 10 and is fixedly installed with the output end of the adjusting motor 14. The left and right side walls of the inner cavity of the equipment frame 10 are symmetrically provided with limiting grooves 15. Two horizontally positioned limiting rods 16 are fixedly connected inside the two limiting grooves 15. Four limiting sliders 17, which are fixedly connected to the left and right ends of two movable support horizontal plates 11, are slidably connected to the outer walls of the two limiting rods 16. Adjusting grooves 20 are provided on the top surfaces of both movable support horizontal plates 11. Positioning mechanisms are provided inside each of the two adjusting grooves 20. The device includes a transverse bidirectional threaded rod 21 rotatably connected to the inside of the adjusting slide 20, two adjusting nut blocks 22 slidably connected to the inside of the adjusting slide 20, and two fixing plates 18 symmetrically fixedly installed on the top of the two adjusting nut blocks 22. The left and right ends of the transverse bidirectional threaded rod 21 are respectively provided with threads in opposite directions and are threadedly connected to the inside of the two adjusting nut blocks 22. Two rubber pads 19 are fixedly installed on the side of the two fixing plates 18 that are close to each other. A drive mechanism for rotating the two transverse bidirectional threaded rods 21 is provided on the left side of the inner cavity of the equipment frame 10. The drive mechanism includes a rotatably connected to the two adjusting nut blocks 22. Two adjusting worms 24 are located on the lower left side of the inner side of the slide groove 20, and a hexagonal slide rod 26 is rotatably connected to the left side of the inner cavity of the equipment frame 10. Two adjusting worm wheels 23 that mesh with the outer walls of the two adjusting worms 24 are fixedly installed on the outer walls of the left ends of the two transverse bidirectional threaded rods 21. Two hexagonal grooves 25 that are adapted to the outer wall surface of the hexagonal slide rod 26 are opened through the two adjusting worms 24. The outer wall surface of the hexagonal slide rod 26 is slidably connected to the two hexagonal grooves 25. The front end of the hexagonal slide rod 26 extends through the front wall surface of the inner cavity of the equipment frame 10 to the outside and is fixedly installed with an adjusting handwheel 27.
[0028] The working principle of this utility model is as follows: During use, based on the length of the furniture to be processed, the output end of the adjusting motor 14 drives the longitudinal bidirectional threaded rod 12 to rotate. This forces the two adjusting threaded sleeves 13, which are threaded to both ends of the longitudinal bidirectional threaded rod 12, to move the two movable support horizontal plates 11 closer to or further apart to adjust their positions. This ensures that the distance between the two movable support horizontal plates 11 matches the length of the furniture. The furniture is then placed at the center of the top surface of the two movable support horizontal plates 11. Rotating the adjusting handwheel 27 drives the hexagonal slide rod 26 to rotate. The hexagonal slide rod 26 drives the two adjusting worm gears 24, which are slidably connected to its surface, to rotate synchronously. This forces the two adjusting worm wheels 23, which mesh with the two adjusting worm gears 24, to drive the two transverse bidirectional threaded rods 21 to rotate synchronously, thereby forcing the two transverse bidirectional threaded rods 21 to rotate synchronously. The four fixed plates 18, threaded to both ends of the threaded rod 21, move closer together to clamp and fix the furniture. The above operation is simple and practical, and the structure is reasonable and compact. This device enables convenient fixing of furniture. Since the adjusting handwheel 27 is located at the front end of the outer side of the equipment frame 10, it is convenient for the staff to operate, improving the ease of use of the device. In addition, no parts extend to the outside of the equipment frame 10 during use, which improves the overall aesthetics of the device and avoids affecting the staff's movement around the device. The four limiting sliders 17 and the two limiting sliders 16 are slidably connected to the outer wall surface, forming a limiting and guiding effect on the left and right ends of the two movable support horizontal plates 11, so that the two movable support horizontal plates 11 can be placed stably inside the equipment frame 10, improving the stability of the device structure.
