Abstract
Description
Technical Field
[0001] The utility model relates to a tooling for turnover and shot blasting, in particular to a tooling for turnover and shot blasting of eccentric gears. Background Art
[0002] The eccentric gear cannot stand vertically on the ground and will fall over. The existing operation is to transfer the eccentric gears one by one using lifting ropes. After the eccentric gears land, additional personnel are needed for auxiliary operation. The eccentric gears are heavy and prone to falling over, so this operation has great risks during the transfer process, and it needs to be completed through cumbersome procedures, consuming time, labor, and manpower, and there are also potential safety hazards.
[0003] Secondly, the eccentric gear needs to be shot blasted. Due to the eccentricity of the eccentric gear, it cannot stand vertically on the ground. The existing operation is for multiple operators to fix the gear respectively, and then hang the shot blasting sling into the gear to complete the lifting and shot blasting. This process also has problems of consuming time, labor, and manpower, and there are also potential safety hazards. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a tooling for turnover and shot blasting of eccentric gears is provided.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a tooling for turnover and shot blasting of eccentric gears, including a base. A counterweight is arranged at the center position of the base. The counterweight has a certain thickness. Blocking frames are evenly arranged at intervals on the outer sides of the sides of the counterweight. The blocking frames have a certain height. The sides of the counterweight cooperate with the blocking frames to form a limiting structure for restricting the front-back movement of the eccentric gear. Columns for restricting the left-right movement of the eccentric gear are arranged on both sides of the limiting structure.
[0006] Further, the limiting structures are evenly distributed along the contour of the base.
[0007] Further, the number of the limiting structures is equal to the number of the lifting positions of the sling before shot blasting, and the distribution positions are also the same.
[0008] Further, pull rings are arranged on the blocking frames.
[0009] Further, the base is circular, the counterweight is an equilateral triangle, and the columns are aligned with the three vertex angles of the counterweight.
[0010] Further, positioning pins are arranged on the base, and positioning holes for plugging and setting with the positioning pins are arranged at the bottoms of the blocking frames.
[0011] Further, the blocking frames are detachably connected to the base.
[0012] The beneficial effects of the present utility model are as follows: A tooling for the turnover and shot peening of an eccentric gear of the present utility model has the characteristics of high efficiency, labor saving, manpower saving, and high safety. Specifically:
[0013] First of all, according to the eccentric direction of the eccentric gear, an auxiliary tooling is made to prevent the eccentric gear from tipping over. At the same time, the tooling should be able to accommodate the placement of multiple products, improving efficiency.
[0014] The eccentric direction of the gear is the convex part of the cam. The cam is embedded in the tooling, and at the same time, a blocking frame is added on one side of the outer web to limit the eccentric gear, improving safety.
[0015] The eccentric gear is placed on the tooling at one time without secondary adjustment. The eccentric gear is stably placed without the risk of tipping over, saving labor and manpower and being safe.
[0016] Secondly, the made tooling can also ensure that the eccentric directions of the eccentric gears are consistent, can meet the quantity requirements during transfer, and can also take into account the use of the shot peening sling, improving efficiency.
[0017] According to the size of the shot peening sling and the quantity of shot peening, the direction of the tooling is customized so that the eccentric gear can exactly match the shot peening when placed on the tooling, improving efficiency.
[0018] Multiple eccentric gears can be placed at one time, with the same direction, exactly matching the shot peening sling, without secondary operation, and can be directly lifted simultaneously, saving labor and manpower and being safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Figures 1 to 5 The tooling shown in the figure for eccentric gear turnover and shot blasting includes a base 1, and a counterweight block 2 is installed at the center position of the base 1 by welding or threaded installation. The counterweight block 2 can reinforce the base 1 to prevent the eccentric gear 4 from being too large or too heavy and causing the base 1 to tip over. The counterweight block 2 has a certain thickness, and blocking frames 3 are installed at intervals on the outer sides of the sides of the counterweight block 2. The blocking frames 3 also have a certain height. The sides of the counterweight block 2 cooperate with the blocking frames 3 to form a limiting structure for limiting the forward and backward movement of the eccentric gear 4, that is, to prevent the eccentric gear 4 from tipping over. Columns 5 for limiting the left and right movement of the eccentric gear 4 are also welded on both sides of the limiting structure. The columns 5 are vertical to the base 1. After the columns are installed, the eccentric gear 4 can be prevented from rolling out from the side.
[0028] In order to prevent tipping over due to unstable center of gravity during movement, the limiting structure is evenly distributed along the contour of the base 1. This design can improve the stability during movement, thereby improving safety.
[0029] Taking into account the existence of a shot blasting process in the present invention, in order to further improve efficiency, the number of limiting structures is equal to the number of lifting positions of the sling 6 before shot blasting, and the distribution positions are also the same. Usually, the shot blasting sling 6 has three lifting positions, so the base 1 in the figure is circular, the counterweight block 2 is an equilateral triangle, and the column 5 is aligned with the three vertex angles of the counterweight block 2.
[0030] In order to ensure the consistency of the limiting distance and facilitate installation, the base 1 is provided with a positioning pin 7, and the bottom of the blocking frame 3 is provided with a positioning hole that is plugged with the positioning pin 7.
[0031] In order to quickly disassemble and assemble the blocking frame, thereby facilitating the removal of the eccentric gear 4, the blocking frame 3 is detachably connected to the base 1, and a pull ring 8 is also provided on the blocking frame.
[0032] refer toFigure 1 During actual use
[0033] The three eccentric gears 4 have been placed into the tooling of the present utility model. The base 1 is transferred below the shot blasting sling 6, and then the shot blasting sling 6 is inserted into the inner holes of the three eccentric gears 4 to complete the integrated lifting and shot blasting.
[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
