Technical Field

[0001] The utility model relates to the technical field of clamping arms, and particularly relates to a clamping device for facilitating the replacement of clamping arms. Background Art

[0002] When serious wear, cracks, deformation or other forms of physical damage occur on the surface of the clamping device, these damages may affect the clamping stability and accuracy, so replacement is required. In some cases, changes in test standards may require the use of a new clamping device to meet specific test requirements.

[0003] During the process of replacing the clamping device, the clamping device may often be composed of multiple components connected by means such as threads and buckles. These complex connection structures may require specific tools and methods for disassembly. Long-term use or lack of maintenance may cause fasteners such as screws and nuts to rust or become stuck, making the disassembly process difficult. Difficult disassembly will prolong the time required for the replacement process, resulting in an increase in the downtime of the production line or work process, and thus affecting the overall production efficiency.

[0004] Therefore, it is necessary to invent a clamping device for facilitating the replacement of clamping arms to solve the above problems. Content of the Utility Model

Specific embodiments

[0021] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0022] The present utility model provides a clamping device for facilitating the replacement of a clamping arm as Figures 1-4 shown, which includes a connection block 2 installed on a position adjusting device and a telescopic assembly 4 installed on the connection block 2. A mounting frame 1 that can slide along the length direction of the connection block 2 is provided at the bottom end of the connection block 2. A clamping assembly 10 is arranged inside the mounting frame 1. The clamping assembly 10 includes a clamping arm body 1001. The output end of the telescopic assembly 4 penetrates through the connection block 2 and extends into the interior of the mounting frame 1. When the telescopic assembly 4 ejects, it can drive the clamping arm body 1001 to perform a clamping operation. A dismantling guide rail 5 for facilitating the assembly of multiple mounting frames 1 is arranged on the side wall of the mounting frame 1. A positioning pin 14 for positioning the mounting frame 1 is also installed on the end face of the connection block 2. When replacing the clamping arm, it is necessary to contract the output end of the telescopic assembly 4 from the interior of the mounting frame 1 to facilitate the sliding of the mounting frame 1 along the connection block 2 and reduce the difficulty of replacing the clamping arm.

[0023] The mounting frame 1 is provided with a positioning hole 7 for inserting the positioning pin 14 and a through hole 8 for the telescopic assembly 4 to pass through at one end located on the connection block 2. Through the arrangement of multiple positioning holes 7, when the clamping arm slides, the positioning pin 14 can be automatically locked under the action of the second reset spring 15, improving work efficiency and saving time costs.

[0024] The clamping assembly 10 includes an ejecting block 1003. An intercepting block 1004 is arranged at one end of the ejecting block 1003 facing the telescopic assembly 4. Two sides of the ejecting block 1003 are provided with first push rods 1002 for driving the clamping arm body 1001 to clamp or release.

[0025] When the telescopic component 4 is ejected, the ejecting block 1003 drives the first push rod 1002 to change from an inclined state to a horizontal state, realizing the clamping of the article by the clamping wall body 1001. The intercepting block 1004 is provided to prevent the first push rod 1002 from changing from a horizontal state to an inclined state when the telescopic component 4 is ejected excessively, resulting in a decrease in the clamping force and avoiding the problem of the article falling off.

[0026] A reset component 11 is arranged inside the mounting frame 1 on the opposite side of the ejecting block 1003. A plurality of first reset springs 12 are arranged inside the reset component 11, and a reset plate 13 is arranged at the ends of the plurality of first reset springs 12.

[0027] The reset component 11 is arranged in a hollow manner. When the telescopic component 4 retracts, the ejecting block 1003 is reset through the action of the first reset springs 12 and the reset plate 13, realizing the release of the clamped article.

[0028] The top end of the positioning pin 14 is connected with a lifting block 9 for synchronously lifting a plurality of positioning pins 14. An installation plate 3 is arranged on the end face of the connecting block 2. A guide rod 16 is arranged at the top end of the positioning pin 14. The top end of the guide rod 16 penetrates and extends to the outside of the installation plate 3, and a second reset spring 15 is sleeved on the guide rod 16 inside the installation plate 3.

[0029] Through the arrangement of the positioning pin 14 and the second reset spring 15, it is convenient to automatically eject through the action of the second reset spring 15 when replacing the clamping arm body 1001, fix the relative positions of the mounting frame 1 and the connecting block 2, reduce the difficulty of disassembly, and improve the efficiency of replacing the clamping arm body 1001.

[0030] One end of the mounting frame 1 is provided with a first side plate 101, a disassembly guide rail 5 is arranged on the end face of the first side plate 101. The other end of the mounting frame 1 is provided with a second side plate 102, a disassembly groove 17 for receiving the disassembly guide rail 5 is opened on the end face of the second side plate 102, and a limiting end face 1701 for positioning is arranged at the end of the disassembly groove 17.

[0031] Through the arrangement of the disassembly guide rail 5 and the disassembly groove 17, it is convenient to install a plurality of clamping arms with different sizes and models on the same horizontal plane, reduce the operation difficulty of replacing the clamping arm, and at the same time, the modular setting is convenient for maintaining the clamping arm and reduces the use cost.

[0032] A guide rail 6 is arranged on the end face of the mounting frame 1 facing the connecting block 2, and the guide rail 6 can slide along the length direction of the connecting block 2.

[0033] When multiple mounting frames 1 are assembled with the disassembly guide rail 5 through the disassembly slots 17, when they are in contact, the guide rails 6 where the multiple mounting frames 1 are located are flush, and all can slide through the connecting block 2. The clamping arm can be replaced by sliding, meeting the usage requirement of facilitating the replacement of the clamping arm.

[0034] In this utility model, some improvements are made to the clamping arm. The telescopic assembly 4 applies pressure to the ejector block 1003 without forming a fixed connection relationship. Thus, during the process of replacing the clamping arm, there is no need to replace or disassemble the telescopic assembly 4. By setting the reset assembly 11, it is used to solve the problem that the clamping arm may stay in place and not reset after the telescopic assembly 4 retracts. Through the setting of the positioning pin 14 and the guide rail 6, the problem that a relatively large number of bolts may need to be disassembled during the process of replacing the clamping arm is solved, facilitating the installation and fixation of the replaced clamping arm, improving work efficiency, and reducing work costs.

[0035] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
