Description

Technical Field

[0001] The invention relates to the technical field of deep hole technology for gun drilling long shaft parts, and in particular to a manipulator automatic feeding and positioning device for gun drilling. Background Art

[0002] The current robot automatic loading and positioning device for gun drilling processing includes a robot, a robot claw and the product injector body to be grasped. The product needs to be automatically loaded into the gun drill positioning sleeve by the robot. The injector needs to be accurately placed in the positioning sleeve hole with a gap of less than 0.02mm, and the product cannot have any scratches or bumps. However, because the positioning part of the product is long and has a high degree of smoothness, and the positioning accuracy of the robot does not meet the requirements, the product is either unable to be installed into the positioning sleeve or is stuck, which brings huge obstacles to automated production.

[0003] To this end, the applicant has conducted useful explorations and attempts and found solutions to the above problems. The technical solutions to be introduced below were produced in this context. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in view of the deficiencies of the prior art, a manipulator automatic feeding and positioning device for gun drilling processing is provided, which reduces labor intensity, improves work efficiency and ensures accurate positioning.

[0005] In order to achieve the above-mentioned purpose of the invention, the robot automatic feeding and positioning device for gun drilling processing of the present invention comprises:

[0006] a bottom plate;

[0007] A linear cylinder mounted on the base plate;

[0008] A positioning body slidably mounted on the guide rail of the base plate, wherein the positioning body is driven to move by the linear cylinder;

[0009] A guide sleeve fixed on the bottom plate, the guide sleeve positions the product pushed into the guide sleeve;

[0010] A V-shaped block fixed on the positioning body, the V-shaped block valve pre-positioning the product placed on the V-shaped block;

[0011] A spring is installed on the positioning body, and the spring elastically pre-positions the product placed on the V-shaped block, so that the product on the V-shaped block can be pushed into the guide sleeve for positioning.

[0012] In a preferred embodiment of the present invention, a spring pick is provided at one end of the spring adjacent to the product. When the product is pre-positioned, the spring pick serves as a flexible positioning device in the front-to-back direction for the robot to grasp the product, so as to ensure that the robot can fully place the grasped product on the robot automatic feeding and positioning device.

[0013] The inventive points of the present invention are as follows:

[0014] 1. Use flexible positioning device to pre-position first and then accurately position

[0015] 2. Because the product has a large aspect ratio and the clearance is within 0.02mm, and the positioning and translation accuracy of the robot is not enough to meet the positioning requirements, the robot is used for pre-positioning, and then the auxiliary device is used for precise positioning, and then the product is clamped for processing. In order to prevent interference and jamming, the positioning device is designed with flexible positioning structures in the horizontal and vertical directions to ensure that the product can be accurately positioned and smoothly translated into the positioning sleeve, thereby ensuring stable processing.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. Simple, reliable, low cost, self-made positioning device can realize automatic loading and unloading and automatic clamping;

[0018] 2. Able to achieve precise positioning that the robot cannot provide;

[0019] 3. Processing automation reduces labor intensity;

[0020] 4. One person can operate multiple devices of the present invention at the same time, and the operator only needs to add materials, which effectively improves labor efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below, but the present invention is not limited to the scope of the embodiments.

[0025] See also Figures 1 to 3The robot automatic loading and positioning device for gun drilling shown in the figure includes: a base plate 1, a linear cylinder 2, a positioning body 3, a guide sleeve 4, a spring 5, a V-shaped block 6, and a spring pick 3

[0026] The bottom plate 1 is the bottom plate of the device, and serves to support the entire device; the linear cylinder 2 is installed on the bottom plate 1, and serves as a mechanism to push the product 8 and the positioning body 3 to move linearly. The positioning body 3 is slidably installed on the guide rail 9 of the bottom plate 1, and the positioning body 3 is driven to move by the linear cylinder. The V-shaped block 6 is fixed on the positioning body 3, and the V-shaped block 6 valve pre-positions the product 8 placed on the V-shaped block 6.

[0027] The guide sleeve 4 is fixed on the base plate 1 , and the guide sleeve 4 positions the product 8 pushed into the guide sleeve 4 through the linear cylinder 2 , the positioning body 3 and the V-block 6 .

[0028] A spring 5 is installed on the positioning body 3, and the spring 5 elastically pre-positions the product 8 placed on the V-shaped block 6, so that the product 8 on the V-shaped block 6 can be pushed into the guide sleeve 4 for positioning. The spring 5 serves to adjust the vertical flexible positioning and buffer the impact force when the robot grasps the product.

[0029] A spring pick 7 is provided at one end of the spring 5 near the product 8. When the product is pre-positioned, the spring pick 7 serves as a flexible positioning device for the robot to grasp the product 8 in the front-to-back direction, so as to ensure that the robot can fully place the grasped product on the robot automatic feeding and positioning device.
