Description

Technical Field

[0001] The utility model relates to mechanical manufacturing, in particular to a robot joint clamp. Background Art

[0002] At present, with the continuous advancement of robot technology, the application of lightweight robot joint products in the fields of industrial automation and service robots is gradually increasing. Lightweight design can not only improve the movement speed and accuracy of robots, but also reduce energy consumption and improve operating efficiency. However, at the same time, lightweight design also brings a series of challenges to the processing and manufacturing of robot joint products.

[0003] On the one hand, due to the weaker structure of lightweight products, traditional clamping and fixing methods may no longer be applicable. During processing, the fixing force of the fixture may cause deformation or instability of the product, affecting the processing quality and precision of the product. On the other hand, when processing thin-walled products, excessive fixing force of the fixture may also cause deformation or stress concentration of the product, thereby affecting the performance and life of the product.

[0004] In addition, the traditional clamping method has become more prominent, and the problem of rebound and stress deformation will occur when the product is released after clamping the product for processing. This not only puts higher requirements on the accuracy and stability of the product, but also may lead to safety hazards during the processing process.

[0005] Therefore, in order to meet the processing and manufacturing needs of lightweight robot joint products, it is necessary to rethink the clamping and fixing solutions. The new fixture design needs to take into account the lightweight characteristics of the product structure, provide sufficient support and stability, and avoid excessive pressure or stress on the product. In addition, it is necessary to find a reliable clamping method that can ensure the stability of the product during processing and avoid rebound or stress deformation.

[0006] In summary, the processing and manufacturing of lightweight robot joint products faces many challenges, which need to be comprehensively considered and solved from the aspects of clamping, fixing, clamping methods, etc. This requires not only the optimization of fixture design and processing technology, but also the combination of actual application scenarios to find suitable solutions to meet the market demand for lightweight robot joint products. Utility Model Content

[0007] The purpose of the utility model is to overcome the defect in the prior art that deformation of the processed parts and clamping stability cannot be taken into account when thin-walled lightweight robot joints are processed, and to provide a robot joint clamp that can maintain clamping stability while preventing defects such as deformation.

[0008] The utility model solves the above technical problems through the following technical solutions:

[0009] A robot joint fixture, characterized in that it includes: a positioning mechanism, the positioning mechanism is fixed to a base plate, and has a portion that matches the shape of a portion of the robot joint to be processed, a clamping cylinder, three or more of the clamping cylinders are arranged on the base plate around the positioning mechanism at intervals, and a side push cylinder, the side push cylinder is also arranged on the base plate around the positioning mechanism, the ejection direction of the side push cylinder is parallel to the base plate and faces the direction outside the positioning mechanism, when the robot joint is placed on the positioning mechanism, the clamping cylinder can be opened and move in a direction perpendicular to the base plate, and keep the robot joint on the positioning mechanism, and the side push cylinder is ejected after opening to keep the robot joint not positioned at the position of the positioning device. Here, when the robot joint is thin-walled, the clamping cylinder is fixed to the positioning device from different directions, and multi-point clamping can be achieved, so that each clamping cylinder does not need to apply too much pressure to cause deformation of the robot joint to be processed. At the same time, the side cylinder can hold the robot joint extended beyond the positioning mechanism after being fixed. Therefore, even if the clamping cylinder does not apply a greater holding force to the robot joint, it can ensure that the robot joint is not prone to rotation during thin-wall processing.

[0010] Preferably, the robot joint fixture further includes a floating support cylinder, which is arranged on the bottom plate within the stroke range of the side push cylinder and can be pushed out perpendicular to the bottom plate. Here, by providing the floating support cylinder, the height of the robot joint outside the positioning mechanism can be adjusted and maintained after positioning, so that the processed robot joint is not prone to flipping.

[0011] Preferably, the positioning mechanism includes a hollow cylindrical part. In this way, a part of the robot joint can rotate according to the required angle during the positioning process to cooperate with the action of the side push cylinder.

[0012] Preferably, the bottom plate around the positioning mechanism is also provided with a plurality of support pins perpendicular to the bottom plate, so that the robot joint and the processing height thereof can be maintained and adjusted by the support pins.

[0013] Preferably, a chip blowing device is also provided on the bottom plate, and the chip blowing device is used to blow air to the processed robot joint to remove the debris generated during processing. That is to say, after processing, the robot joint can be transported to a position directly facing the chip blowing device. The chip blowing device then blows air to remove the debris. Here, the robot joint can be held by other clamping cylinders on the air supply path directly facing the chip blowing device.

[0014] In summary, by setting a plurality of clamping cylinders and side-pushing cylinders to cooperate with each other to hold the robot joint to be processed on the positioning mechanism, the robot joint is fixed to the positioning device from different directions by the clamping cylinders, and multi-point clamping can be achieved, so that each clamping cylinder does not need to apply excessive pressure to cause deformation of the robot joint to be processed. At the same time, the side-pushing cylinder can hold the part of the robot joint that extends outside the positioning mechanism after being fixed, so even if the clamping cylinder does not apply a greater holding force to the robot joint, it can ensure that the robot joint is not easy to rotate and displace during thin-wall processing.

[0017] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings.

[0018] Figure 1 , is a schematic diagram of the three-dimensional structure of a robot joint fixture according to an embodiment of the utility model, Figure 2 , is a schematic diagram of a top view of a robot joint fixture according to an embodiment of the present utility model. Figure 1 , 2As shown, the robot joint fixture of the utility model comprises: a positioning mechanism 1, the positioning mechanism 1 is fixed to a base plate 2, and has a portion matching the shape of a part of the robot joint to be processed (not shown in the figure), a clamping cylinder 3, more than three clamping cylinders 3 are arranged on the base plate 2 around the positioning mechanism 1 at intervals, and a side push cylinder 4, the side push cylinder 4 is also arranged on the base plate 2 around the positioning mechanism 1, and the ejection direction of the side push cylinder 4 is parallel to the base plate 2 and faces the direction outside the positioning mechanism 1. When the robot joint is placed on the positioning mechanism 1, the clamping cylinder 3 can be opened and moved in a direction perpendicular to the base plate 2, and the robot joint is kept on the positioning mechanism 1. The side push cylinder 4 is ejected after being opened to keep the robot joint not positioned at the position of the positioning device. Here, when the robot joint is thin-walled, the clamping cylinder 3 is fixed to the positioning device from different directions, and multi-point clamping can be achieved, so that each clamping cylinder 3 does not need to apply too much pressure to cause deformation of the robot joint to be processed. At the same time, the side push cylinder 4 can hold the part of the robot joint that is extended outside the positioning mechanism 1 after being fixed, so even if the clamping cylinder 3 does not apply a greater holding force to the robot joint, it can ensure that the robot joint is not prone to rotation during thin-wall processing. In this embodiment, the clamping cylinder 3 can position the robot joint by extending and retracting.

[0019] Furthermore, the robot joint fixture also includes a floating support cylinder 5, which is arranged on the bottom plate 2 within the stroke range of the side push cylinder 4, and can be pushed out perpendicular to the bottom plate 2. Here, by setting the floating support cylinder 5, the height of the robot joint outside the positioning mechanism 1 can be adjusted and maintained after the robot joint is positioned, so that the processed robot joint is not easy to flip.

[0020] Furthermore, the positioning mechanism 1 includes a hollow cylindrical portion. In this way, a part of the robot joint can rotate according to the required angle during the positioning process to cooperate with the action of the side push cylinder 4.

[0021] Furthermore, a plurality of support pins 6 perpendicular to the bottom plate 2 are also provided on the bottom plate 2 around the positioning mechanism 1. The support pins 6 can be used to maintain and adjust the robot joint and its processing height.

[0022] Furthermore, a chip blowing device 7 is also provided on the bottom plate 2, and the chip blowing device 7 is used to blow air to the robot joint after processing to remove the debris generated during processing. That is to say, after processing, the robot joint can be transported to the position directly facing the chip blowing device 7. The chip blowing device 7 then blows air to remove the debris. Here, the robot joint can be held by other clamping cylinders 3 on the air supply path directly facing the chip blowing device 7.

[0023] The uniqueness of the robot joint fixture design of the utility model lies in its innovative structure and function. First, it adopts a multi-point clamping design, and fixes the robot joint to the positioning device from different directions through more than three clamping cylinders 3, thereby avoiding the problem of excessive pressure and product deformation that may be caused by single-point clamping. At the same time, the setting of the side-pushing cylinder 4 ensures the stability of the robot joint after clamping, and prevents the occurrence of rotation during thin-wall processing.

[0024] Furthermore, by adding the floating support cylinder 5, the robot joint can be vertically ejected within the ejection stroke range to adjust and maintain the height of the robot joint after positioning, thereby avoiding the robot joint from flipping. In addition, the hollow cylindrical portion of the positioning mechanism 1 enables the robot joint to rotate according to the required angle during the positioning process to cooperate with the action of the side ejection cylinder 4.

[0025] The support pins 6 perpendicular to the bottom plate 2 are arranged on the bottom plate 2, which further enhances the support and adjustment function of the robot joint and its processing height. These support pins 6 can effectively maintain the stability and accuracy of the robot joint during the processing.

[0026] Finally, the chip blowing device 7 enables the robot joint to remove the generated chips in time after processing, keeping the processing environment clean. The synergistic effect of the other clamping cylinders 3 ensures that the robot joint can remain stable during the chip blowing process and will not move accidentally due to air supply.

[0027] In summary, the robot joint clamp of the utility model is not only innovative in clamping and fixing, but also fully considered and realized in terms of functionality and practicality, providing reliable support and guarantee for the processing and manufacturing of robot joint products.
