Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder production and processing technology, specifically to a hydraulic cylinder production positioning tooling. Background Technology

[0002] Hydraulic cylinders are widely used in industrial and mechanical equipment. For example, in jacks, the hand cranking speed directly affects the hydraulic oil flow, thus changing the lifting speed. Adjusting the pressure valve setting controls the output force. Hydraulic cylinders come in various structural forms, including piston, plunger, telescopic, and swing types, suitable for different application scenarios. During the production process of hydraulic cylinders, specialized positioning fixtures are needed to assist in shaping, cutting, or grinding. Some existing hydraulic cylinder production positioning fixtures use a fixed length and thickness of the clamping unit for positioning and clamping hydraulic cylinder components. This type of positioning fixture has some problems. For example, the fixed length and thickness of the clamping unit limits the stability and applicability of the fixture for clamping hydraulic cylinder components of different lengths and thicknesses, affecting the accuracy of the positioning work.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a hydraulic cylinder production positioning fixture, including a positioning table 1, a drive mechanism 2 and a lifting drive mechanism 3;

[0022] Positioning platform 1: It has symmetrically distributed sliding openings 7 inside, and sliding seats 8 are slidably connected inside each sliding opening 7. Clamping seats 9 are slidably connected inside each sliding seat 8. A support frame 12 is provided at the lower end of the positioning platform 1. A lifting plate 4 is slidably connected between the support frame 12 and the positioning platform 1. A control switch group 15 is provided at the front end of the upper surface of the positioning platform 1. The input end of the control switch group 15 is electrically connected to an external power supply. Sliding columns 5 are fixedly connected between the positioning platform 1 and the support frame 12. Guide cylinders 6 are provided at the four corners of the lifting plate 4. The middle part of each sliding column 5 is slidably connected to the interior of the vertically adjacent guide cylinder 6.

[0023] Drive mechanism 2: It is located inside the lifting plate 4. The lower ends of the clamping seats 9 are all threadedly connected to the middle of the drive mechanism 2. The drive mechanism 2 includes a motor 21, a driving helical gear 22, a rotating shaft 23, a driven helical gear 24, and a double-acting screw 25. The motor 21 is located at the rear end of the upper surface of the lifting plate 4. The front end of the output shaft of the motor 21 is fixedly connected to the driving helical gear 22. The upper end of the lifting plate 4 is fixedly connected to symmetrically distributed supports. The rotating shaft 23 is rotatably connected between the two supports. The middle of the rotating shaft 23 is fixedly connected to the driven helical gear 24. The driving helical gear 22 and the driven helical gear 24 are meshed. The left and right ends of the rotating shaft 23 are both fixedly connected to the double-acting screw 25. The lower ends of the clamping seats 9 are all threadedly connected to the middle of the shaft 23. The corresponding end of the vertically adjacent bidirectional lead screw 25 is threaded. The input end of the motor 21 is electrically connected to the output end of the control switch group 15. According to the length of the hydraulic cylinder production assembly, the motor 21 is operated by the control switch group 15. The output shaft of the motor 21 rotates, which drives the drive helical gear 22 to rotate, which in turn drives the driven helical gear 24 to rotate. The driven helical gear 24 rotates, which drives the rotating shaft 23 to rotate, ultimately realizing the rotation of the two bidirectional lead screws 25. The rotation of the bidirectional lead screws 25 causes the two horizontally adjacent clamping seats 9 to move towards each other. The two clamping seats 9 moving towards each other cause the corresponding sliding seats 8 to slide towards each other inside the same sliding opening 7, thereby realizing the adjustment of the distance between the two horizontally adjacent clamping seats 9.

[0024] Lifting drive mechanism 3: It is used for lifting the lifting plate 4. The lifting drive mechanism 3 includes a connecting plate 35, a connecting rod 36, and a connecting seat 37. The connecting seats 37 are evenly fixedly connected to the lower end of the lifting plate 4 and the upper end of the support frame 12. The connecting rods 36 are rotatably connected inside the connecting seats 37. The ends of two vertically adjacent connecting rods 36 near the center of the support frame 12 are rotatably connected to the same connecting plate 35. The lifting drive mechanism 3 also includes a telescopic cylinder 31, a drive seat 32, a drive rod 33, and a drive column 34. The telescopic cylinder 31 is disposed on the support frame 12. At the lower end of the telescopic cylinder 31, the upper end of the piston rod is fixedly connected to a drive seat 32. Both the front and rear ends of the drive seat 32 are rotatably connected to symmetrically distributed drive rods 33. Two longitudinally adjacent connecting plates 35 are fixedly connected to oil-filling drive columns 34. The ends of the drive rods 33 furthest from the drive seat 32 are rotatably connected to the middle of the laterally adjacent drive columns 34. The air port of the telescopic cylinder 31 is connected to the air outlet of an external air pump via a conduit. The input end of the external air pump is electrically connected to the output end of the control switch group 15. The motor 21 is shut off via the control switch group 15, thus realizing the external... When the external air pump operates, it controls the telescopic cylinder 31 to move. The piston rod of the telescopic cylinder 31 retracts, causing the drive seat 32 to move downwards. The downward movement of the drive seat 32 causes the ends of the four drive rods 33 closest to the center of the support frame 12 to move downwards. The ends of the four drive rods 33 furthest from the center of the support frame 12 pull the corresponding drive column 34 towards the center of the support frame 12. When two drive columns 34 move towards each other, they both cause the adjacent connecting seats 37 to move towards the center of the support frame 12. The movement of the center causes the corresponding ends of the connecting rods 36 to move closer to the center of the support frame 12, so that the upper ends of the four connecting rods 36 on the upper side pull the lifting plate 4 down through the corresponding connecting seats 37. The guide cylinders 6 slide on the outer surface of the corresponding sliding column 5 to provide guidance for the vertical movement of the lifting plate 4. The downward movement of the lifting plate 4 drives the four clamping seats 9 to move down through the drive mechanism 2. The clamping seats 9 slide downward inside the corresponding sliding seat 8. The top plate 14 and the vertically adjacent pressure plate 13 work together to achieve stable clamping of the hydraulic cylinder production components.

[0025] The clamping base 9 is fixedly connected to a top plate 14 at its upper end, and the sliding base 8 is fixedly connected to a bottom plate 13 at its upper end. A spring 10 is fixedly connected to the lower end of the top plate 14 and the upper end of the bottom plate 13. A buffer plate 11 is fixedly connected to the corresponding end of each of the two vertically adjacent springs 10. Ribs are provided in the middle of the inner surfaces of the two horizontally adjacent clamping bases 9. The buffer plates 11 are slidably connected to the horizontally adjacent ribs. The two vertically adjacent buffer plates 11 are vertically aligned. All buffer plates 11 are rubber plates. When the buffer plates 11 contact the hydraulic cylinder production assembly, the corresponding springs 10 are elastically compressed. The elastic force of the springs 10 reacts to the corresponding buffer plates 11. The buffer plates 11 provide buffer protection for the hydraulic cylinder production assembly in the positioning clamping system. Simultaneously, the buffer plates 11 slide within the corresponding ribs, ensuring the stability of the buffer plate 11's movement.

[0026] The working principle of the hydraulic cylinder production positioning fixture provided by this utility model is as follows: During operation, the operator first places the positioning table 1, support frame 12, and other mechanisms stably in the horizontal working area. After stable placement, the operator, based on the length of the hydraulic cylinder production assembly, controls the switch group 15 to activate the motor 21. The output shaft of the motor 21 rotates, driving the drive helical gear 22 to rotate, which in turn drives the driven helical gear 24 to rotate. The driven helical gear 24 rotates, driving the rotating shaft 23 to rotate, ultimately causing the two bidirectional lead screws 25 to rotate. The rotation of the bidirectional lead screws 25 causes the two horizontally adjacent clamps to rotate. The gripping seats 9 move towards each other, and the movement of two gripping seats 9 towards each other causes the corresponding sliding seats 8 to slide towards each other within the same sliding opening 7, thereby adjusting the distance between two horizontally adjacent gripping seats 9. When the gripping seats 9 move to the desired position, the operator turns off the motor 21 by controlling the switch group 15 and starts the external air pump. The external air pump controls the telescopic cylinder 31 to operate, and the piston rod of the telescopic cylinder 31 retracts. The retraction of the piston rod of the telescopic cylinder 31 causes the drive seat 32 to move down. The downward movement of the drive seat 32 causes the ends of the four drive rods 33 closest to the center of the support frame 12 to move down. The ends furthest from the center of the support frame 12 pull the corresponding drive column 34 towards the center of the support frame 12. The movement of two drive columns 34 towards each other causes adjacent connecting seats 37 to move towards the center of the support frame 12. The movement of connecting seats 37 towards the center of the support frame 12 causes the corresponding ends of connecting rods 36 to move towards the center of the support frame 12. This causes the upper ends of the four connecting rods 36 on the upper side to pull the lifting plate 4 downwards through the corresponding connecting seats 37. The guide cylinders 6 slide on the outer surface of the corresponding sliding columns 5, providing guidance for the vertical movement of the lifting plate 4. The downward movement of the lowering plate 4 drives the four clamping seats 9 to move downward through the drive mechanism 2. The clamping seats 9 slide downward inside the corresponding sliding seats 8. The top plate 14 and the vertically adjacent pressure plate 13 work together to achieve stable clamping of the hydraulic cylinder production assembly. At the same time, when the buffer plate 11 contacts the hydraulic cylinder production assembly, the corresponding spring 10 is elastically compressed. The elastic force of the spring 10 reacts to the corresponding buffer plate 11. The buffer plate 11 provides buffer protection for the hydraulic cylinder production assembly in the positioning and clamping. At the same time, the buffer plate 11 slides inside the corresponding rib groove to ensure the stability of the movement of the buffer plate 11.

[0027] It is worth noting that the motor 21 disclosed in the above embodiments can be a 5I K120A-AF motor, and the control switch group 15 is provided with control buttons that correspond one-to-one with the motor 21 and the external air pump and control their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
