Description

Technical Field

[0001] The utility model relates to a manipulator, in particular to a manipulator with variable spacing for taking out pieces on a quenching press in a heat treatment production line. Background Art

[0002] The quenching press is a very important heat treatment equipment on the heat treatment production line. For press-quenched heat-treated products, it is necessary to use corresponding molds to perform limited-shape press quenching on specific products to reduce or even eliminate the workload of subsequent production links, greatly saving production costs and improving the qualification rate of heat-treated quenched products.

[0003] In the field of press-quenched products, the main products are annular products, such as bearing rings, gears, gear rings, etc. In order to save production costs, the same quenching press can often meet the press-quenching of products of different types, specifications and shapes by replacing the quenching mold. At the same time, in order to meet the needs of modern automated production, production equipment manufacturers often use automatic loading robots to load the molds. For products with different outer diameters, especially when the outer diameters differ greatly, finished product grippers are often used in the process of grasping the workpiece. The movement range of the finished product gripper is limited. When changing products, it is necessary to manually adjust the basic position of the gripper. Therefore, it will have a certain impact on production efficiency during this period. Utility Model Content

DETAILED DESCRIPTION

[0012] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] like Figure 1-Figure 3 As shown, the utility model relates to a variable-pitch manipulator for picking up parts on a quenching press in a heat treatment production line, comprising a mounting plate 1 and an open slot 2, wherein four open slots 2 are radially arranged along the center of the mounting plate 1, and further comprising a variable-pitch driving mechanism, a variable-pitch actuator and a rotary claw 3, wherein the variable-pitch driving mechanism is composed of a rotary cylinder 4, a driving gear 5 and a driving rack 6, wherein the rotary cylinder 4 is fixedly arranged at the center position on the mounting plate 1, and the driving gear 5 is fixedly mounted on the rotating output end of the rotary cylinder 4, and four driving racks 6 are arranged in an upper and lower layer at 90° and meshed with the driving gear 5, and one end of each driving rack 6 is respectively fixedly connected to the corresponding variable-pitch actuator, and the rotary claw 3 is fixed on the actuator end of the variable-pitch actuator located below the mounting plate 1.

[0014] As a further embodiment, the variable-pitch actuator is composed of a connecting block 7, a linear guide 8, a guide slider 9 and a transmission seat 10. The four linear guides 8 are fixed in a central radial pattern on the bottom of the mounting plate 1 at the corresponding opening slots 2. The guide slider 9 is arranged in the corresponding linear guide 8. The upper end of the transmission seat 10 is connected to the corresponding driving rack 6 through the connecting block 7. The lower part of the transmission seat 10 passes through the opening slot 2 and the linear guide 8 and is inserted and fixed on the guide slider 9. The lower end of the transmission seat 10 is fixed to the corresponding rotary air claw 3.
