Description

Technical Field

[0001] The utility model relates to an auxiliary mechanism for a pulley jump detection device, in particular to a workpiece transmission device for the pulley jump detection device. Background Art

[0002] At present, in the process of detecting the end face runout and side face runout of the belt installation groove of the pulley, the workpiece needs to be transferred to the detection station through the corresponding workpiece transmission mechanism, and the workpiece needs to be driven to rotate at the detection station. The detection head of the side detection dial gauge is directly in contact with the belt installation groove to detect the side face runout of the belt installation groove of the workpiece during the rotation process; then the detection head of the end face runout detection dial gauge is longitudinally abutted against the end face of the side detection dial gauge, the end face runout is transmitted through the side detection dial gauge, and then the end face runout amount is detected by the end face runout detection dial gauge.

[0003] In order to prevent excessive mechanical damage to the workpiece due to fixed clamping during the rotational drive process, the rotational drive components of the existing workpiece transmission mechanism mostly use flexible clamping components when clamping the workpiece. However, since the side detection dial indicator will form a reaction force on the workpiece when it abuts against the belt installation groove of the workpiece, the flexible clamping will cause the workpiece itself to form a slight shake under the drive of the reaction force, thereby affecting the accuracy of the workpiece runout detection. Directly using rigid clamping will cause mechanical wear on the surface of the workpiece, which is very troublesome.

[0004] Therefore, the research purpose of the present utility model is to design a workpiece transmission device for pulley runout detection equipment that can not only stably clamp and rotationally drive the workpiece, but also prevent the workpiece from excessive mechanical damage due to rigid friction during the clamping process. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a workpiece transmission device for a pulley runout detection device, which can effectively solve the technical problems existing in the above-mentioned prior art.

A corresponding rigid cylinder is rotatably installed on the first mounting plate. The first mounting plate is driven by a corresponding first lifting drive mechanism. A corresponding partition is fixedly connected below the top of the rigid cylinder. A number of corresponding guide holes are arranged in a circular array on the rigid cylinder above the partition. Corresponding jacking rods are respectively movably inserted into the guide holes. A corresponding elastic compression block is fixedly installed in the rigid cylinder above the partition. The top of the elastic compression block is located above the top of the rigid cylinder.

[0010] The pressing-down component includes a second mounting plate that is liftably arranged on the frame above the upper side of the set of pulley belts. A corresponding pressing-down fixing piece is rotatably installed on the second mounting plate. The pressing-down fixing piece faces the elastic compression block. A cylindrical elastic piece with the bottom located below the bottom of the pressing-down fixing piece is fixedly sleeved around the periphery of the pressing-down fixing piece. The second mounting plate is driven by a corresponding second lifting drive mechanism.

[0011] The rotation drive mechanism is used to drive the rigid cylinder to rotate.

[0012] A set of horizontal support rods are horizontally and fixedly connected to the frame below the pulley belts. A corresponding guide groove is provided on the upper end surface of the horizontal support rods. The upper side of the pulley belts is embedded in the guide grooves of the horizontal support rods, and the upper end parts of the pulley belts extend above the horizontal support rods.

[0013] The rotation drive mechanism includes a transmission wheel fixedly connected to the bottom side of the rigid cylinder. The transmission wheel is connected to the output shaft end of a corresponding drive motor by a belt drive method.

[0014] A set of corresponding stop rods are arranged on one side of the feeding end of the set of pulley belts. The stop rods are driven by corresponding stop rod drive cylinders.

[0015] A corresponding material detection sensor is provided above a set of the stop rods through a corresponding support plate.

[0016] A set of corresponding stop cylinders are fixedly installed on the frame in front of the pushing component. The piston rod ends of the set of stop cylinders are oppositely arranged and fixedly connected with corresponding buffer stop blocks.

[0018] The jacking rods are made of engineering plastics, and the outer ends of the jacking rods are respectively arranged in a spherical shape.

[0019] Advantages of the present utility model:

[0020] 1) The present utility model makes collaborative improvements to the pushing component and the pressing component. After clamping the workpiece, the end faces of the rigid cylinder and the pressing fixing part respectively abut against the end faces of the workpiece to form a stroke limit for the workpiece in the longitudinal direction; while the elastic compression block and the cylindrical elastic member are respectively compressed to clamp the workpiece; in addition, the tightening rod moves outward under the push of the elastic compression block and abuts against the inner side wall of the workpiece, so that a stroke limit for the workpiece can be formed in the transverse direction. Thus, it can not only fully clamp and fix the workpiece, but also form a stroke limit for the workpiece in the longitudinal and transverse directions respectively on the premise of not causing excessive mechanical damage to the workpiece, so as to ensure that the rotation process of the workpiece does not generate shaking and offset, and to ensure the accuracy of the runout detection.

[0022] 3) A stop rod is provided on one side of the feeding end of the pulley transmission belt of the present utility model, and a material detection sensor is provided on the upper part of the stop rod through a support plate. Before feeding, the stop rod extends to block the workpiece. After the material detection sensor detects that the workpiece is in place, the stop rod retracts to output the workpiece at a fixed point; then, a buffer stop block is driven to extend by a stop cylinder provided on the frame in front of the pushing component to position and block the incoming material. Through time delay setting, it is ensured that the workpiece can be stably conveyed to the position where the buffer stop block is located, so as to externally place the material detection sensor at the feeding end, thereby realizing the accurate positioning and conveying of the workpiece on the premise of preventing the influence on the clamping and rotation driving of the workpiece.
