Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, and in particular to a support frame for hydraulic cylinder processing. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and a venting device. However, in the production of hydraulic cylinders, existing hydraulic cylinders are directly placed on support frames, resulting in poor fixation. When the support frame is subjected to external forces and shakes, the hydraulic cylinder can easily fall off the support frame, causing accidents or damage. Furthermore, it cannot be adapted to hydraulic cylinders of different sizes and lengths, thus presenting certain limitations. Utility Model Content

[0003] The purpose of this utility model is to provide a support frame for machining hydraulic cylinders, which solves the problems mentioned in the background art and facilitates its promotion.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A support frame for machining hydraulic cylinders includes a base plate, with upright plates symmetrically connected to both sides of the top of the base plate. A support plate is fixedly connected to the top of the upright plates. The upper surface of the support plate has two symmetrically formed strip-shaped through holes. A dual-axis drive motor is fixedly connected to the top of the base plate. A threaded rod 1 and a threaded rod 2 are fixedly connected to the output end of the dual-axis drive motor. The ends of threaded rod 1 and threaded rod 2 away from the output end of the dual-axis drive motor are rotatably connected to the upright plates. Threaded blocks are threaded onto threaded rod 1 and threaded rod 2. A connecting rod is fixedly connected to the top of the threaded blocks. The connecting rod is located away from the threaded rod. One end of the block passes through strip-shaped through holes one and two and is fixedly connected to a fixing plate. A vertical sleeve is symmetrically connected to the top of the fixing plate. A vertical rod is slidably connected inside the vertical sleeve. A top plate is fixedly connected to the top of the vertical rod. A lower clamp and an upper clamp are fixedly connected to the opposite side of the fixing plate and the top plate, respectively. Multiple evenly arranged circular holes are opened on the vertical rod. A fixing block is fixedly connected to the outer wall of the vertical sleeve. A rectangular groove is opened inside the fixing block. Rectangular blocks are slidably connected to the inner walls on both sides of the rectangular groove. A threaded rod three is rotatably connected to one side of the rectangular block. A cylinder is symmetrically connected to the end of the rectangular block away from the threaded rod three.

[0006] Furthermore, the end of the threaded rod three away from the rectangular block passes through the fixing block and is threadedly connected to the fixing block, and a knob is fixedly connected to one end of the threaded rod three.

[0007] Furthermore, the end of the cylinder furthest from the rectangular block passes through the vertical sleeve and engages with the circular hole.

[0008] Furthermore, the threads of threaded rod one and threaded rod two have opposite directions of rotation.

[0009] Furthermore, the rectangular groove is symmetrically provided with sliding grooves on both sides, and the rectangular block is symmetrically provided with sliders on both sides, with the sliding grooves and sliders being slidably connected.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model discloses a support frame for machining hydraulic cylinders. In use, a dual-axis drive motor is started. The rotation of the motor drives threaded rod one and threaded rod two, which in turn moves a threaded block on threaded rod one and threaded rod two, thereby moving a fixing plate. This allows for the support and fixation of hydraulic cylinders of different lengths. The hydraulic cylinder to be machined is then placed on top of the lower fixture. Rotating the threaded rod three with a knob moves the rectangular block, disengaging the cylinder from the circular hole and releasing the vertical rod from its fixed position. The top plate is then moved up and down via the vertical rod, causing the upper fixture at the bottom of the top plate to contact the top of the hydraulic cylinder. Rotating the threaded rod three again moves the rectangular block, causing the two cylinders to move into the circular hole, thus fixing the vertical rod in position. This maintains the clamping and fixing effect of the upper fixture on the bottom hydraulic cylinder, improving stability and the efficiency of subsequent hydraulic cylinder machining.

[0020] Depend on Figures 1 to 4As shown, a support frame for machining hydraulic cylinders includes a base plate 1. Vertical plates 2 are symmetrically connected to both sides of the top of the base plate 1. A support plate 3 is fixedly connected to the top of the vertical plates 2. The upper surface of the support plate 3 has symmetrically formed strip-shaped through holes 4 and 5. A dual-axis drive motor 6 is fixedly connected to the top of the base plate 1. Threaded rods 7 and 8 are fixedly connected to the output end of the dual-axis drive motor 6. The ends of threaded rods 7 and 8 away from the output end of the dual-axis drive motor 6 are rotatably connected to the vertical plates 2. Threaded blocks 9 are threadedly connected to threaded rods 7 and 8. A connecting rod 10 is fixedly connected to the part. The end of the connecting rod 10 away from the threaded block 9 passes through the first strip-shaped through hole 4 and the second strip-shaped through hole 5 and is fixedly connected to a fixing plate 11. A vertical sleeve 12 is symmetrically connected to the top of the fixing plate 11. A vertical rod 13 is slidably connected inside the vertical sleeve 12. A top plate 14 is fixedly connected to the top of the vertical rod 13. A lower clamp 15 and an upper clamp 16 are fixedly connected to the opposite side of the fixing plate 11 and the top plate 14, respectively. A plurality of evenly arranged round holes 17 are opened on the vertical rod 13. A fixing block 18 is fixedly connected to the outer wall of the vertical sleeve 12. A rectangular groove 19 is opened inside the fixing block 18. Rectangular blocks 20 are slidably connected to the inner walls of both sides of the groove 19. A threaded rod 21 is rotatably connected to one side of each rectangular block 20. A cylinder 22 is symmetrically connected to the end of the rectangular block 20 away from the threaded rod 21. When the dual-axis drive motor 6 is started, its rotation drives the threaded rods 7 and 8 to rotate, which in turn moves the threaded block 9 on the threaded rods 7 and 8, thereby moving the fixing plate 11. This allows for the support and fixation of hydraulic cylinders of different lengths. The hydraulic cylinder to be processed is then placed on top of the lower fixture 15. Rotating knob 23 on threaded rod 21 moves rectangular block 20, causing cylinder 22 to disengage from circular hole 17, releasing the position fixation of vertical rod 13. Top plate 14 is then moved up and down via vertical rod 13, causing upper clamp 16 at the bottom of top plate 14 to move and contact the top of hydraulic cylinder. Rotating knob 23 on threaded rod 21 again causes rectangular block 20 to move two cylinders 22 into circular hole 17, thereby fixing the position of vertical rod 13 and maintaining the clamping and fixing effect of upper clamp 16 on bottom hydraulic cylinder, improving stability and the efficiency of subsequent processing of hydraulic cylinder.

[0021] The end of the threaded rod 21 away from the rectangular block 20 passes through the fixed block 18 and is threadedly connected to the fixed block 18. A knob 23 is fixedly connected to one end of the threaded rod 21. By setting the knob 23, the threaded rod 21 can be rotated. The threaded rod 21 is threadedly connected to the fixed block 18. When the knob 23 is rotated, the threaded rod 21 can be moved.

[0022] The end of the cylinder 22 away from the rectangular block 20 passes through the vertical sleeve 12 and is engaged with the circular hole 17. The engagement of the cylinder 22 with the circular hole 17 ensures the stability of the upper clamp 16 when clamping and fixing the bottom hydraulic cylinder.

[0023] The threads of thread rod 7 and thread rod 8 have opposite directions of rotation. By setting thread rod 7 and thread rod 8 with opposite directions of rotation, the threaded blocks 9 can move towards each other or relative to each other.

[0024] The rectangular groove 19 has symmetrical sliding grooves 24 on both sides, and the rectangular block 20 has symmetrical sliders 25 on both sides. The sliding grooves 24 and sliders 25 are slidably connected. The sliders 25 slide in the sliding grooves 24 to ensure the stability of the rectangular block 20 when it moves.

[0025] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
