Description

Technical Field

[0001] The utility model relates to the technical field of torque converter pump wheel clamps, and specifically discloses a torque converter pump wheel clamp. Background Art

[0002] The hydraulic torque converter is also called "hydraulic torque converter", "turbine torque converter" or "dynamic hydraulic torque converter". It is a type of hydraulic transmission component. It consists of a pump wheel, a turbine wheel and a guide wheel. The pump wheel is generally cast from aluminum metal, with many relatively flat blades radially installed inside. The inner edge of the blade is equipped with a guide ring to allow the transmission oil to flow smoothly. It is made (or welded) into one piece with the torque converter housing and connected to the engine.

[0003] In order to use an industrial manipulator to grab the pump wheel and perform automated processing on the pump wheel, it is necessary to design a clamp for the industrial manipulator to clamp the pump wheel. For example, the patent with announcement number CN114147601B discloses a turbine processing manipulator assembly and a processing unit thereof, wherein the turbine processing manipulator assembly includes a first manipulator and a second manipulator, wherein the end effector of the first manipulator includes a first gripper mounting plate and a first gripper and a second gripper mounted on the first gripper mounting plate, and both the first gripper and the second gripper can clamp the turbine to be processed.

[0004] The above solution has the following problems:

[0005] 1. The first gripper mounting plate is set in a plane, which results in a longer end length of the manipulator after it is connected to the first gripper mounting plate. When the width of the loading port on the protective door side facing the machining center is narrow, interference is prone to occur, resulting in unsmooth loading and unloading of the machining center by the manipulator.

[0006] 2. The first manipulator can grab the turbine of the torque converter from the outside, but because a flange-like convex edge is provided on the bottom surface of the torque converter pump wheel, the second manipulator cannot stably grab the pump wheel from the outside. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides a torque converter pump wheel clamp to solve the problem that after the manipulator is connected to the first gripper mounting plate, interference is easily caused when the manipulator is used to load and unload materials to the machining center due to its long end length.

[0008] To achieve the above purpose, the technical solution of the utility model is:

[0009] A torque converter pump wheel fixture includes a mounting plate, chucks are arranged on the bottom surfaces of both sides of the mounting plate, auxiliary claws are fixedly arranged on the claws of the chucks, the mounting plate includes a concave plate; flat plates are fixedly arranged on both sides of the concave plate; and the chucks are arranged on the bottom surface of the flat plate. The arrangement of the concave plate can reduce the length of the end of the manipulator after the manipulator is connected to the concave plate, avoiding interference when the manipulator is used to load and unload materials to a machining center.

[0010] Preferably, a through hole is provided in the middle of the concave plate to facilitate connection with the robot.

[0011] Preferably, the auxiliary claw includes a connecting plate; a boss is fixedly provided at one end of the connecting plate; the connecting plate is connected to the claw of the chuck by bolts. The setting of the boss increases the contact area between the auxiliary claw and the pump wheel, increases friction, and ensures the stability of the auxiliary claw when supporting the pump wheel.

[0012] Preferably, the connecting plate is provided with threaded holes to facilitate the use of bolts to connect the claws of the chuck.

[0013] Preferably, a groove is provided on the boss, and a rubber pad is glued in the groove. When the auxiliary claw is used to support the pump wheel, the rubber pad is used to reduce the friction with the pump wheel blades to avoid damaging the pump wheel blades.

[0014] Preferably, the outer side of the boss is provided with an arc surface, so as to facilitate the cooperation with the inner ring of the pump wheel and ensure the stability of the auxiliary claw when supporting the pump wheel.

[0015] The beneficial effects of the utility model are:

[0016] 1. The setting of the concave plate can reduce the length of the end of the manipulator after the manipulator is connected to the concave plate, avoiding interference when the manipulator is used to load and unload materials to the machining center.

[0017] 2. Through the reasonable setting of the auxiliary claws, the pump wheel can be supported from the inside to avoid unstable grasping caused by the convex edge when grasping the pump wheel from the outside. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1 As shown, a torque converter pump wheel clamp includes a mounting plate 1, chucks 2 are arranged on the bottom surfaces of both sides of the mounting plate 1, auxiliary claws 3 are fixedly arranged on the claws of the chucks 2, and the mounting plate 1 includes a concave plate 101; flat plates 102 are fixedly arranged on both sides of the concave plate 101; and chucks 2 are arranged on the bottom surface of the flat plate 102.

[0028] In the above arrangement, a through hole is provided in the middle of the concave plate 101 to facilitate connection with the manipulator 5. Fixed plates 4 are provided on the flat plate 102 at intervals; the chuck 2 is fixedly provided on the fixed plate 4. The specific connection arrangement between the fixed plate 4 and the flat plate 102 belongs to the prior art and has been disclosed in the patent announcement number CN114147601B, which will not be repeated here.

[0029] like Figure 2As shown, the auxiliary claw 3 includes a connecting plate 301; a boss 302 is fixedly provided at one end of the connecting plate 301; and the connecting plate 301 is connected to the claw of the chuck 2 by bolts. The setting of the boss 302 increases the contact area between the auxiliary claw 3 and the pump wheel 6, increases the friction, and ensures the stability of the auxiliary claw 3 when supporting the pump wheel 6. The connecting plate 301 is provided with a threaded hole, which is convenient for connecting the claw of the chuck 2 with bolts. The boss 302 is provided with a groove 303; a rubber pad is glued in the groove 303. When the auxiliary claw 3 is used to support the pump wheel 6, the rubber pad is used to reduce the friction with the blades of the pump wheel 6 to avoid damaging the blades of the pump wheel 6. The outer side of the boss 302 is provided with an arc surface 304, which is convenient for matching with the inner ring of the pump wheel 6 to ensure the stability of the auxiliary claw 3 when supporting the pump wheel 6. Through the reasonable setting of the auxiliary claw 3, the pump wheel 6 can be supported from the inside, avoiding the unstable grasping caused by the existence of the convex edge when grasping the pump wheel 6 from the outside.

[0030] like Figure 3-4 As shown, when in use, the output end of the manipulator 5 is connected to the through hole of the concave plate 101. The chuck 2 is a pneumatic three-jaw chuck. The auxiliary claw 3 is driven by the chuck 2 to support the pump wheel 6. The axial distance between the upper end of the output end of the manipulator 5 and the bottom surface of the pump wheel 6 is short, which can avoid interference when the manipulator 5 is used to load and unload materials to the machining center, wherein the axial direction refers to the centerline direction of the through hole of the concave plate 101.
