Description

Technical Field

[0001] This utility model relates to the field of parts clamping technology, specifically an adjustable clamping device. Background Technology

[0002] During mechanical assembly, it is often necessary to assemble the stepped ring assembly onto the inner wall of the cabin. After the stepped ring is pressed into place in sections, threaded connections and non-destructive testing are performed.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0004] Because the force plane of the stepped ring and the force plane of the cabin are not on the same plane and are in opposite directions, the stepped ring assembly is currently pressed by hand using the handle of a general-purpose tool. The existing tool does not have the function of torque amplification and cannot be matched with the plane of the product being pressed, which makes the work difficult and labor-intensive, and cannot meet the needs of mass production and long-term operation.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable clamping device, which solves the problem that the current method of clamping the stepped ring assembly manually using the handle of a general-purpose tool is difficult to operate and cannot meet the needs of mass production and long-term operation.

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

[0008] An adjustable clamping device includes a main rod, a cabin body located on one side of the bottom of the main rod, and a stepped ring assembly disposed on the top of one side of the cabin body. A sliding cylinder is slidably installed on the outer side of the main rod, and an L-shaped connecting rod is fixedly installed on the bottom of the sliding cylinder. A first clamping assembly is fixedly installed on the bottom of one end of the main rod, and a second clamping assembly is fixedly connected to one end of the L-shaped connecting rod.

[0009] Preferably, the front end of the sliding cylinder is fitted with an L-shaped locking screw via a threaded rotation, and the rear end of the L-shaped locking screw is made of rubber.

[0010] Preferably, the front end of the main rod is fitted with limit screws located on both sides of the sliding cylinder via a threaded rotation, and one end of the main rod is fitted with an anti-collision plug.

[0011] Preferably, a rubber handle is sleeved and installed at the other end of the main rod, and the surface of the rubber handle is evenly distributed with anti-slip texture.

[0012] Preferably, the first clamping assembly includes an adjusting nut, a connecting shaft, a clamping plate, and a rubber pad. The adjusting nut is screwed and rotated to the bottom of one side of the main body rod. The connecting shaft is fixed to the bottom of the adjusting nut. The clamping plate is fixed to the bottom of the connecting shaft. The rubber pad is fixed to the bottom of the clamping plate.

[0013] Preferably, the second clamping assembly includes a connector, a screw, a clamping block, and a positioning hole. The connector is fixedly installed on one side of the bottom end of the L-shaped connecting rod. The screw is rotatably installed inside the connector via a thread. The top of the clamping block has a through-hole. The clamping block is located on the top of the connector, and a bolt extending into the interior of the connector is provided through the positioning hole.

[0014] Compared with the prior art, this utility model provides an adjustable clamping device with the following advantages: This utility model maximizes the gap between the first clamping component and the second clamping component by sliding the sliding cylinder, which facilitates subsequent operations. By contacting the upper surface of the first clamping component with the stepped ring component and the lower surface of the top of the other side of the main body of the cabin with the second clamping component, and then increasing the upward force by lifting the main body rod, the first clamping component and the second clamping component clamp the stepped ring component under the action of the lever balance force. This facilitates the installation of products for non-destructive testing and avoids the problem that the current method of clamping the stepped ring component by hand using the handle of a general tool is difficult and cannot meet the needs of mass production and long-term operation.

[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] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an adjustable clamping device.

[0022] Please see Figures 1-4 An adjustable clamping device includes a main rod 1, a cabin body 2 located on one side of the bottom of the main rod 1, and a stepped ring assembly 3 disposed on the top of one side of the cabin body 2. A sliding cylinder 101 is slidably installed on the outer side of the main rod 1, and an L-shaped connecting rod 102 is fixedly installed on the bottom of the sliding cylinder 101. A first clamping assembly 4 is fixedly installed on the bottom of one end of the main rod 1, and a second clamping assembly 5 is fixedly connected to one end of the L-shaped connecting rod 102.

[0023] Through the above structural design, the adjustable clamping device maximizes the gap between the first clamping component 4 and the second clamping component 5 by sliding the sliding cylinder 101, facilitating subsequent operations. By contacting the first clamping component 4 with the upper surface of the stepped ring component 3, and then sliding the sliding cylinder 101 to a suitable position, the second clamping component 5 contacts the lower surface of the top of the other side of the cabin body 2. Then, by lifting the main body rod 1 to increase the upward force, under the balance of lever torque, the stepped ring component 3 moves downward under the downward clamping force of the main body rod 1. When the cabin body 2 and... After the mating surfaces of the stepped ring assembly 3 are pressed and fitted into place, the main rod 1 stops moving, and the clamping device also stops moving, achieving static balance. After the stepped ring assembly 3 is pressed into place, the screws between the two products are installed. After the products are installed, the force of the clamping device handle is released, the L-shaped locking screw 103 is loosened, and the sliding cylinder 101 is moved to the other side, thereby removing the entire clamping device. This solves the problem that the current method of using the handle of a general-purpose tool to clamp the stepped ring assembly 3 by pure manual means is difficult to work and cannot meet the needs of mass production and long-term operation.

[0024] Furthermore, an L-shaped locking screw 103 is threadedly mounted on the front end of the sliding cylinder 101, and the rear end of the L-shaped locking screw 103 is made of rubber. When the sliding cylinder 101 moves to a suitable position, rotating the L-shaped locking screw 103 causes its rear end to move threadedly into the sliding cylinder 101. This allows the rubber block at the rear end of the L-shaped locking screw 103 to fit tightly against the surface of the main body rod 1, increasing the friction of the contact surface. This locks the sliding cylinder 101 in a suitable position outside the main body rod 1, facilitating operation by the operator.

[0025] Furthermore, the front end of the main body rod 1 is fitted with limiting screws 104 located on both sides of the sliding cylinder 101 via a threaded rotation, and an anti-collision plug 106 is sleeved on one end of the main body rod 1. The limiting screws 104 limit the movement of the sliding cylinder 101 to a limited position outside the main body rod 1, preventing excessive movement that would hinder operation. The anti-collision plug 106 protects one end of the main body rod 1 from damage due to impact.

[0026] Furthermore, a rubber handle 105 is sleeved and installed at the other end of the main body rod 1, and the surface of the rubber handle 105 is evenly distributed with anti-slip texture. This allows the worker to easily use the main body rod 1 to exert force by gripping the rubber handle 105, and the evenly distributed anti-slip texture on the surface of the rubber handle 105 prevents the worker's hand from slipping when gripping it.

[0027] Furthermore, the first clamping assembly 4 includes an adjusting nut 401, a connecting shaft 402, a clamping plate 403, and a rubber pad 404. The adjusting nut 401 is screwed and rotated to the bottom of one side of the main body rod 1. The connecting shaft 402 is fixed to the bottom of the adjusting nut 401, the clamping plate 403 is fixed to the bottom of the connecting shaft 402, and the rubber pad 404 is fixed to the bottom of the clamping plate 403. Rotating the adjusting nut 401 allows the connecting shaft 402 to move the clamping plate 403 up and down to adjust its height, facilitating the operator to adjust the clamping plate 403 to a suitable height for clamping the device. The rubber pad 404 is made of polyurethane, generating significant friction when in contact with the stepped ring assembly 3, ensuring contact strength and eliminating the risk of product impact.

[0028] Furthermore, the second clamping assembly 5 includes a connector 501, a screw 502, a clamping block 503, and a positioning hole 504. The connector 501 is fixedly installed on one side of the bottom end of the L-shaped connecting rod 102. The screw 502 is rotatably installed inside the connector 501 via a thread. The top of the clamping block 503 has a through-hole 504. The clamping block 503 is located on the top of the connector 501, and a bolt extending into the connector 501 is installed through the positioning hole 504. The clamping block 503 is fixedly installed on the top of the connector 501 by the bolt extending through the positioning hole 504 into the connector 501. By rotating the screw 502, the clamping block 503 can be moved up and down to adjust to a suitable height for clamping the device. The clamping block 503 is made of polyurethane, which generates significant friction when in contact with the main body 2 of the chamber, ensuring contact strength and eliminating the risk of product impact, thus improving the clamping safety of the device.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
