Description

Technical Field

[0001] This utility model belongs to the field of spring manufacturing technology, and in particular relates to an adjustable clamp for the production of nitrogen springs. Background Technology

[0002] A nitrogen spring is a mechanical device that uses nitrogen pressure as an elastic medium. It is widely used in applications where energy needs to be stored and released. It typically consists of a sealed cylinder, a piston, a nitrogen-filled chamber, and a piston rod. Energy is stored by compressing nitrogen and then released when needed to drive the piston. To facilitate the production of nitrogen springs, clamps are often used to hold and fix them.

[0003] A search revealed that CN216759637U, published on June 17, 2022, discloses an adjustable fixture for nitrogen spring production. The fixture includes a mounting plate and a clamping assembly. Fixing bolts are installed at both ends of the mounting plate, and a limit block is fixed to the upper right end of the mounting plate. An adjusting plate is rotatably connected inside the limit block, and a rotating assembly for rotation is located at the upper left end of the adjusting plate. The clamping assembly is located at the right end of the rotating assembly. The clamping assembly includes a clamping frame, a clamping motor, a rotating plate, a limit groove, a clamping rod, a guide groove, and an anti-slip sleeve. This adjustable fixture for nitrogen spring production, through the clamping assembly, allows for clamping nitrogen springs. First, the nitrogen spring is placed at the top center of the clamping frame. Then, the clamping motor is activated to rotate the rotating plate, causing the clamping rod to move inward under the combined action of the guide groove and the limit groove. This enables clamping and positioning of nitrogen springs of different diameters, thus improving the fixture's applicability.

[0004] Existing technology uses three clamping rods to clamp and fix the nitrogen spring. However, the clamping height of the clamping rods is fixed. When the length of the nitrogen spring is long, the stability of the clamped nitrogen spring in the clamped state is poor. In addition, existing technology adjusts the clamping direction of the nitrogen spring by rotating the adjusting plate. However, existing technology can only adjust the nitrogen spring to be in a horizontal or vertical state, which limits the adjustment range of the nitrogen spring state. At the same time, the fixed clamping height of the nitrogen spring in existing technology cannot be adjusted according to actual needs.

[0005] To address these issues, we provide an adjustable clamp for manufacturing nitrogen springs. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable clamp for the production of nitrogen springs. The distance between the upper and lower clamping plates is adjustable, and the clamping rod is inserted into the corresponding insertion hole. Furthermore, the operation of the electric push rod solves the problems of poor clamping stability when clamping long nitrogen springs in the prior art, the fact that the prior art can only adjust the nitrogen spring to a horizontal or vertical state, resulting in a limited range of adjustment for the nitrogen spring state, and the fact that the clamping height of the nitrogen spring is fixed in the prior art, making it impossible to adjust the operating height of the nitrogen spring according to actual needs.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an adjustable clamp for manufacturing nitrogen springs, comprising a clamping mechanism. The clamping mechanism includes a rotating plate, with gears arranged in a circular array below the rotating plate. A lower clamping plate is arranged in a circular array above the rotating plate at the location of gears, and an upper clamping plate is arranged above the lower clamping plate. Guide sleeves are fixed at both ends of the upper wall of the lower clamping plate, and guide rods are provided with a clearance fit inside the guide sleeves. The upper end of the guide rods is fixedly connected to the corresponding upper clamping plate. An adjustment mechanism is provided outside the clamping mechanism, comprising an electric push rod. A moving plate is fixed at the upper end of the electric push rod, and a circular plate is arranged on one side above the moving plate. An insertion rod is arranged on one side of the circular plate. Insertion holes are formed in a circular array at the location of the insertion rod, and the insertion rod is inserted into the corresponding insertion hole.

[0009] The present invention is further configured such that the top of the peripheral wall of any guide sleeve above each lower clamping plate is threaded with a bolt, and the inner end of the bolt abuts against the corresponding guide rod.

[0010] The present invention is further configured such that a connecting rod is fixed at the middle position of the upper wall of the gear, the connecting rod is rotatably connected to the rotating plate through a bearing, and the upper end of the connecting rod is fixedly connected to the corresponding lower clamping plate.

[0011] The present invention is further configured such that a mounting plate is provided below the first gear, a motor is fixed at the middle position of the lower wall of the mounting plate, and a second gear is fixed on the power output shaft of the motor, the second gear being meshed with the first gear.

[0012] The present invention is further configured such that the upper wall of the mounting plate is fixed with fixing rods in a circumferential array, and the upper end of the fixing rods is fixedly connected to the rotating plate.

[0013] The present invention is further configured such that side plates are fixed on both sides of the upper wall of the movable plate, and a rotating rod is fixed at the middle position of the circular plate. The rotating rod is fixedly connected to the mounting plate and is rotatably connected to the side plates through bearings.

[0014] The present invention is further configured such that an L-shaped plate is provided on the outside of the insertion rod, the L-shaped plate is fixedly connected to the corresponding side plate, an elastic element is sleeved on the outside of the insertion rod, a baffle is fixed on the side of the elastic element near the round plate, the two ends of the elastic element abut against the corresponding L-shaped plate and the baffle respectively, and a pinch block is fixed on the end of the insertion rod away from the round plate.

[0015] The present invention is further configured such that a base plate is fixed to the lower end of the electric push rod, and a limit sleeve is fixed in a circumferential array along the edge of the upper wall of the base plate. A lifting rod is provided in the internal gap of the limit sleeve, and the upper end of the lifting rod is fixedly connected to the moving plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up an upper clamping plate, a guide sleeve, a guide rod, and a lower clamping plate, allows for the following: When the length of the nitrogen spring being clamped is short, the bolts are loosened, and the upper clamping plate is moved downwards to shorten the distance between the upper and lower clamping plates. This prevents the upper clamping plate from being too high, which could hinder the operation of the nitrogen spring during clamping and fixing. When the length of the nitrogen spring being clamped is long, the bolts are loosened, and the upper clamping plate is moved upwards to increase the distance between the upper and lower clamping plates, thereby increasing the clamping length of the nitrogen spring and improving the stability when clamping it.

[0018] 2. This utility model, by setting up a circular plate, insertion holes, insertion rods, and electric push rods, allows for multi-angle adjustment of the vertical angle of the clamping mechanism by inserting the insertion rods into different insertion holes. The operation of the electric push rods drives the moving plate to move up and down accordingly, ultimately driving the clamping mechanism and the nitrogen spring to move up and down, thereby achieving the purpose of adjusting the operating height of the nitrogen spring.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-3This utility model relates to an adjustable clamp for manufacturing nitrogen springs, comprising a clamping mechanism 1. The clamping mechanism 1 includes a rotating plate 101. Three gears 103 are arranged in a circular array below the rotating plate 101. The three gears 103 are of the same size and move synchronously. A lower clamping plate 108 is arranged in a circular array above the rotating plate 101 at the position corresponding to the location of the gears 103. An upper clamping plate 107 is arranged above the lower clamping plate 108. This clamping mechanism is used to clamp and fix the nitrogen spring. Both the upper clamping plate 107 and the lower clamping plate 108 are in contact with the nitrogen spring. By adjusting the distance between the lower clamping plate 108 and the upper clamping plate 107, nitrogen springs of different lengths can be stably clamped and fixed. Guide sleeves 105 are fixed at both ends of the upper wall of the lower clamping plate 108. A guide rod 106 is provided in the internal clearance of the guide sleeve 105. The cooperation between the guide sleeve 105 and the guide rod 106 allows the upper clamping plate 107 to move up and down relative to the corresponding lower clamping plate 108. The upper end of the guide rod 106 is fixedly connected to the corresponding upper clamping plate 107.

[0032] Specifically, a bolt 105a is threadedly connected to the top of the peripheral wall of any guide sleeve 105 above each lower clamping plate 108. The inner end of the bolt 105a abuts against the corresponding guide rod 106. In this state, the guide rod 106 and the guide sleeve 105 are relatively fixed. When adjusting the distance between the upper clamping plate 107 and the corresponding lower clamping plate 108, the bolt 105a is loosened to disengage from the guide rod 106. At this time, the guide rod 106 and the guide sleeve 105 are in a movable state, so the height of the upper clamping plate 107 can be adjusted.

[0033] A connecting rod 103a is fixed at the middle position of the upper wall of gear 103. The connecting rod 103a is rotatably connected to the rotating plate 101 through a bearing. The upper end of the connecting rod 103a is fixedly connected to the corresponding lower clamping plate 108. With the above configuration, when gear 103 rotates, it drives the connecting rod 103a to rotate, causing the corresponding lower clamping plate 108 to rotate.

[0034] A mounting plate 102 is provided below gear 103. A motor 104 is fixed at the middle position of the lower wall of the mounting plate 102. The power output shaft of the motor 104 passes through the mounting plate 102 and extends to the top of the mounting plate 102. A gear 2 109 is fixed on the power output shaft of the motor 104. Gear 2 109 is located between the rotating plate 101 and the mounting plate 102. Gear 2 109 is meshed with gear 103. With the above arrangement, by making the motor 104 work to drive gear 2 109 to rotate, the three gears 103 can rotate synchronously.

[0035] The upper wall of the mounting plate 102 is fixed with fixing rods 102a in a circumferential array, and the upper end of the fixing rods 102a is fixedly connected to the rotating plate 101.

[0036] The operation process of this embodiment is as follows: According to the length of the nitrogen spring, the operating bolt 105a is disengaged from the corresponding guide rod 106. At this time, the operating clamp moves up and down to adjust the distance between the upper clamp 107 and the lower clamp 108. After the adjustment is completed, the operating bolt 105a rotates and abuts against the corresponding guide rod 106, placing the nitrogen spring in the middle position above the rotating plate 101. The motor 104 works to drive the gear 109 to rotate, thereby causing the gear 103 to rotate and drive the connecting rod 103a to rotate. Finally, the nitrogen spring is clamped and fixed under the joint action of the upper clamp 107 and the lower clamp 108.

[0037] Example 2

[0038] Please see Figure 1 , 2 4 and 5 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: an adjustment mechanism 2 is provided on the outside of the clamping mechanism 1. The adjustment mechanism 2 includes an electric push rod 205, which is used to drive the moving plate 202 to move up and down to adjust the height of the nitrogen spring. The moving plate 202 is fixed at the upper end of the electric push rod 205. A circular plate 201 is provided on one side above the moving plate 202. A plug rod 206 is provided on one side of the circular plate 201. The circular plate 201 at the position of the plug rod 206 has a circular array of insertion holes 201a. The plug rod 206 is inserted into the corresponding insertion hole 201a. By inserting the plug rod 206 into different insertion holes 201a, the angle of the clamping mechanism 1 can be adjusted to adjust the angle of the nitrogen spring at multiple angles.

[0039] Specifically, side plates 203 are fixed on both sides of the upper wall of the movable plate 202, and a rotating rod 201b is fixed at the middle position of the circular plate 201. The rotating rod 201b is fixedly connected to the mounting plate 102, and the rotating rod 201b is rotatably connected to the side plate 203 through a bearing. With the above configuration, the clamping mechanism 1 can be rotated by rotating the rotating rod 201b.

[0040] An L-shaped plate 208 is provided on the outside of the insertion rod 206. The L-shaped plate 208 is fixedly connected to the corresponding side plate 203. An elastic element 207 is sleeved on the outside of the insertion rod 206. A baffle 206b is fixed on the side of the elastic element 207 near the circular plate 201 corresponding to the outside of the insertion rod 206. Under normal conditions, the baffle 206b is in close contact with the surface of the circular plate 201. The two ends of the elastic element 207 abut against the corresponding L-shaped plate 208 and the baffle 206b, respectively. A pinch block 206a is fixed on the end of the insertion rod 206 away from the circular plate 201. By operating the pinch block 206a, the insertion rod 206 moves away from the circular plate 201, causing the insertion rod 206 to disengage from the insertion hole 201a, thereby adjusting the angle of the clamping mechanism 1.

[0041] The lower end of the electric push rod 205 is fixed with a base plate 204. The base plate 204 can be fixed to the mounting platform with screws. The upper wall of the base plate 204 is fixed with a limit sleeve 204a in a circular array along the edge. The limit sleeve 204a is fitted with a lifting rod 202a with a gap. The upper end of the lifting rod 202a is fixedly connected to the moving plate 202. With the above configuration, when the electric push rod 205 works, it drives the moving plate 202 to move up and down accordingly. At this time, the lifting rod 202a and the limit sleeve 204a move relative to each other. The cooperation between the lifting rod 202a and the limit sleeve 204a can prevent the moving plate 202 from tilting.

[0042] The remaining structure is the same as in Example 1;

[0043] The operation process of this embodiment is as follows: After clamping and fixing the nitrogen spring, operate the pinch block 206a to move away from the circular plate 201, so that the insertion rod 206 is disengaged from the insertion hole 201a. At this time, according to the actual use requirements, operate the clamping mechanism 1 to rotate and adjust the nitrogen spring to a suitable vertical angle, and then release the force on the pinch block 206a so that the insertion rod 206 can be inserted into the corresponding insertion hole 201a.

[0044] When the height of the nitrogen spring needs to be adjusted, the electric push rod 205 is activated to move the moving plate 202 up and down accordingly.

[0045] In addition, the motor 104 and electric push rod 205 in the adjustable clamp produced by this nitrogen spring are electrically connected to an external power source through conductive wires. At the same time, the motor 104 and electric push rod 205 are existing technologies, and their models are not limited here.
