Description

Technical Field

[0001] The present application belongs to the technical field of clamping components, and in particular, relates to a clamping claw mechanism. Background Art

[0002] The clamping assembly is a common device used to clamp products in automation. The existing clamping assembly only has the function of clamping. Some products also need some other functions. For example, some special-shaped products need to be fixed in position when they are in the next process. Generally, the multi-angle positioning assembly fixes them on the module, which is convenient for the clamping assembly to move. However, this fixation will make it difficult for the robot to remove the product from the module to the next process when the next process is carried out. Therefore, it is particularly important to have the function of fixing the position of the product during the movement of the clamping product. In this way, the product can be firmly fixed on the module. When the clamping assembly drives it to the next process, another robot can also take it away conveniently. Therefore, a new technology is proposed. Utility Model Content

[0027] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0028] This embodiment provides a clamping mechanism, including a main connecting seat 1 and clamping assemblies 2 at both ends thereof, each set of clamping assemblies 2 is provided with at least two clamps 3, and the clamps 3 are installed on the main connecting seat 1 at intervals and side by side; each clamp 3 includes a connecting plate 3.1, a lifting module 3.2, a mounting plate 3.3, a bidirectional moving module 3.4, a first clamp 3.5, a second clamp 3.6, and a stripping mechanism 3.7;

[0029] The connecting plate 3.1 is installed under the main connecting seat 1, the lifting module 3.2 is installed on one side of the connecting plate 3.1, and the mounting plate 3.3 is installed on the slider of the lifting module 3.2. The lifting module 3.2 drives the two-way moving module 3.4 to move up and down. There are two first clamping pieces 3.5, which are respectively installed on the two moving blocks of the two-way moving module 3.4. The two-way moving module 3.4 drives the first side clamping pieces 3.5 to move toward or away from each other to realize the action of clamping the module or not clamping the module;

[0030] There are four second clips 3.6, and every two of them are installed on two sides of the mounting plate 3.3 away from the first clips 3.5. The length of the second clips 3.6 is set according to the height of the module;

[0031] There are two stripping mechanisms 3.7, which are installed on both sides of the bottom of the mounting plate 3.3 and are located between the two first clamps 3.5. The bottom of the stripping mechanism 3.7 abuts against the product module, so that when the first clamp of the utility model product is not clamped, the module can be quickly detached from the utility model product. The first clamp 3.5 is provided with an opening 3.9 that allows the stripping mechanism 3.7 to pass through and move. The opening 3.9 is a strip hole that allows the stripping mechanism 3.7 to move horizontally.

[0032] The first clamping piece 3.5 is L-shaped, and its short end is mounted on the moving card of the bidirectional moving module 3.4. The first clamping piece 3.5 is provided with an opening 3.9, and the inner side surface of the lower end of the first clamping piece 3.5 is provided with two clamping protrusions 3.51, which are arranged relatively spaced apart. The second clamping piece 3.6 and the first clamping piece 3.5 are both provided with a weight-reducing hole 3.11.

[0033] The stripping mechanism 3.7 includes a guide column 3.71, a guide sleeve 3.72, and a buffer spring 3.73. One end of the guide column 3.71 is connected to the mounting plate 3.3, and the other end is inserted into the guide sleeve 3.72 and can move along the axis in the guide sleeve 3.72. The buffer spring 3.73 is sleeved on the outside of the guide column 3.71 and is located above the guide sleeve 3.72. A sliding limit assembly is provided between the guide sleeve 3.72 and the guide column 3.71, so that the stripping mechanism 3.7 can press against product modules of different thicknesses, thereby increasing its practicality.

[0034] The sliding limit assembly includes positioning holes 3.74 provided axially on both sides of the guide sleeve 3.72, the virtual connection line of the positioning holes 3.74 coincides with the center line of the main connecting plate 1, and positioning pins 3.75 are provided on both sides of the guide column 3.71 located in the guide sleeve 3.72, and the positioning pins 3.75 can move the positioning holes 3.74.

[0035] A rubber pad 3.76 is installed under the guide sleeve 3.72 to prevent squeezing. A connecting block 3.77 is also provided between the guide column 3.71 and the mounting plate 3.3. The connecting block 3.77 is close to the first clamping piece 3.5 to reduce the exposed part of the buffer spring 3.73 to avoid accidental injury or clamping of people or objects when the buffer spring 3.73 is deformed.

[0036] Finally, the lifting module 3.2 is a cylinder or a slide, or other structures capable of achieving lifting. The bidirectional moving module 3.4 is a bidirectional sliding block, which drives the two first clamps to move toward or away from each other.

[0037] When the utility model product is used, the main connecting plate is installed on the movable module. When the product module needs to be clamped, the lifting module drives the first clamp to be misaligned with the main connecting piece, and then the bidirectional movable module drives the clamping claws to move away from each other until it can completely cover the product module. Then the bidirectional movable module drives the clamping claws to move towards each other to clamp the product module. At this time, the second clamp can be clamped on the other two sides of the product module. In this way, the first clamp and the second clamp form four surrounding angles to clamp the product module, which can firmly clamp the product, and the second clamp is adapted to the shape of the module so that it can fit the product. This will make it difficult for the product module to detach from the utility model product due to the fit, so a stripping mechanism is provided to eject the product module through the elastic force of the buffer spring.

[0038] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
