Description

Technical Field

[0001] The utility model relates to a belt pulley rotation transmission mechanism, which is mainly applied to a belt pulley runout detection device, used for driving the belt pulley to rotate, and transmitting the runout amount of the belt pulley mounting groove of the belt pulley outwards during the rotation process, so as to facilitate the convenient and accurate detection of the runout amount. Background Art

[0002] After each key process of the existing belt pulley, such as stamping, spinning process, etc., there are runout size requirements for the contact surface between the belt pulley and the belt, that is, there are runout size requirements for the belt mounting groove of the belt pulley. The runout detection of the belt mounting groove of the belt pulley mainly includes end face runout detection and side face runout detection.

[0003] At present, during the end face runout detection and side face runout detection of the belt mounting groove of the belt pulley, it is necessary to use a corresponding belt pulley rotation transmission mechanism to fix the belt pulley workpiece and drive it to rotate. Since the belt pulley rotation transmission mechanism only simply drives the belt pulley workpiece to rotate and cannot directly transmit the runout of its belt mounting groove outwards. Therefore, during the subsequent detection process, only a side detection dial indicator that can be horizontally movably installed can be directly contacted with the belt mounting groove to detect the side face runout of the belt mounting groove; then the detection head of the end face runout detection dial indicator is longitudinally abutted against the end face of the side detection dial indicator, and the end face runout is transmitted through the side detection dial indicator, and then the end face runout amount is detected through the end face runout detection dial indicator. This results in a relatively large operation difficulty in the entire detection process and relatively low detection accuracy.

[0004] Therefore, the research purpose of the present utility model is to design a belt pulley rotation transmission mechanism that can not only fix the belt pulley workpiece and drive it to rotate stably, but also synchronously transmit the runout of the belt mounting groove outwards during the rotation drive of the workpiece, thereby improving the operation difficulty and detection accuracy of the detection process. Summary of the Invention

[0005] Aiming at the technical problems existing in the above-mentioned prior art, the present utility model provides a belt pulley rotation transmission mechanism, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present utility model is as follows:

[0007] A belt pulley rotation transmission mechanism, comprising:

[0008] A frame, on which a first mounting plate and a second mounting plate for clamping a workpiece up and down are arranged in a liftable manner. A driving support assembly is rotatably mounted on the first mounting plate and is rotationally driven by a corresponding rotational driving mechanism. A driven support assembly corresponding to the driving support assembly is rotatably mounted on the second mounting plate;

[0009] A first lifting driving mechanism is arranged on the frame and is used for driving the first mounting plate to lift;

[0010] A second lifting driving mechanism is arranged on the frame and is used for driving the second mounting plate to lift;

[0011] A beating conduction assembly includes a fixing plate movably mounted on the frame. A corresponding beating transmission rod is fixedly mounted on the fixing plate through a corresponding flexible connection mechanism. A guide wheel with one end inserted horizontally into a belt mounting groove of the workpiece is rotatably mounted at the end of the beating transmission rod.

[0012] The driving support assembly includes a rigid cylinder rotatably mounted on the first mounting plate. A corresponding partition plate is fixedly connected below the top of the rigid cylinder. A plurality of corresponding guide holes are arranged in an annular array on the rigid cylinder above the partition plate. Corresponding pressing rods are respectively movably inserted into the guide holes. A corresponding elastic compression block is fixedly mounted in the rigid cylinder above the partition plate, and the top of the elastic compression block is located above the top of the rigid cylinder.

[0013] The driven support assembly includes a downward pressing and fixing member rotatably mounted on the second mounting plate. The downward pressing and fixing member faces the elastic compression block, and a cylindrical elastic member with the bottom located below the bottom of the downward pressing and fixing member is fixedly sleeved on the periphery of the downward pressing and fixing member.

[0014] When the first mounting plate moves upward and the second mounting plate moves downward, the end faces of the rigid cylinder and the downward pressing and fixing member respectively abut against the end faces of the workpiece. The elastic compression block and the cylindrical elastic member are respectively compressed to clamp the workpiece. The pressing rods move outward under the push of the elastic compression block and abut against the inner side wall of the workpiece.

[0015] The flexible connection mechanism includes a group of connection blocks fixedly connected to the fixing plate and the beating transmission rod. The two sides of the connection block are supported and connected by a group of elastically inclined metal plates.

[0016] Both the first lifting driving mechanism and the second lifting driving mechanism adopt lifting driving cylinders.

[0017] The fixed plate is driven by a fixed plate driving mechanism fixedly mounted on the frame, and the fixed plate driving mechanism adopts a lead screw transmission mechanism.

[0018] The rotation drive mechanism comprises a transmission wheel fixedly connected to the bottom side of the rigid cylinder, and the transmission wheel is connected to the output shaft end of the corresponding driving motor through a belt drive.

[0019] The outer ends of the tightening rods are respectively arranged in a spherical shape.

[0020] Advantages of the utility model:

[0021] 1) The utility model clamps the workpiece through the active support component and the driven support component, and then contacts the belt installation groove of the workpiece through the guide wheel of the jumping transmission component. Since the jumping transmission rod of the jumping transmission component is installed through a flexible connection mechanism, under the drive of the rotation drive mechanism, the workpiece in the rotation process can fully transmit the end face jump and side jump of its belt installation groove to the outside through the jumping transmission rod. At this time, it is only necessary to use a set of dial indicators to detect the end face jump and side jump of the jumping transmission rod respectively, so that the pulley workpiece can be fixed and stably driven to rotate, and the jump of the belt installation groove can be synchronously transmitted to the outside during the rotation drive of the workpiece, so as to improve the operation difficulty and detection accuracy of the detection process.

[0022] 2) In order to prevent excessive mechanical loss to the workpiece, the existing active support components and driven support components mostly use flexible clamping when clamping the workpiece. Since the guide wheel will form a reaction force on the workpiece during the bouncing transmission process with the workpiece, the use of flexible clamping will cause the workpiece itself to shake, thereby affecting the accuracy of the workpiece bouncing detection. To this end, the utility model makes coordinated improvements to the specific structures of the active support component and the driven support component, so that after the workpiece is clamped, the end faces of the rigid cylinder and the downward pressing fixing member are respectively abutted against the end faces of the workpiece to form a stroke limit on the workpiece in the longitudinal direction; and the elastic compression block and the tubular elastic member are respectively compressed to clamp the workpiece; in addition, the clamping rod moves outward under the push of the elastic compression block and presses against the inner wall of the workpiece, so that the stroke limit of the workpiece can be formed in the lateral direction. Thereby, the workpiece can be fully clamped and fixed, and without causing excessive mechanical damage to the workpiece, the workpiece can be limited in stroke longitudinally and transversely to ensure that the workpiece does not shake or deflect during its rotation, thereby ensuring that the end face runout and side runout of the workpiece can be transmitted outwardly with high precision through the runout transmission rod, thereby further ensuring the accuracy of runout detection.

[0023] 3) The flexible connection mechanism of the present utility model includes a group of connection blocks fixed to the fixed plate and the beating transmission rod. The two sides of the connection block are supported and connected by a group of elastically inclined metal plates. Under the buffering effect of the elastically inclined metal plates, the freedom of movement of the beating transmission rod is ensured to ensure the practical effect of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail below in conjunction with the accompanying drawings:

[0029] Refer to Figures 1-3 , a belt pulley rotary transmission mechanism, including:

[0030] Frame 1, on which a first mounting plate 3 and a second mounting plate 4 for clamping the workpiece 2 up and down are arranged in a liftable manner. A driving support assembly 6 rotatably mounted on the first mounting plate 3 is rotationally driven by a corresponding rotation drive mechanism 5, and a driven support assembly 7 corresponding to the driving support assembly 6 is rotatably mounted on the second mounting plate 4;

[0031] First lifting drive mechanism 8, arranged on the frame 1, for driving the first mounting plate 3 to lift;

[0032] Second lifting drive mechanism 9, arranged on the frame 1, for driving the second mounting plate 4 to lift;

[0033] The beating conduction assembly 10 includes a fixing plate 1001 movably installed on the frame 1. A corresponding beating transmission rod 1003 is fixedly installed on the fixing plate 1001 through a corresponding flexible connection mechanism 1002. A guide wheel 1004 with its end horizontally rotatably installed is inserted into the belt installation groove of the workpiece 2 at the end of the beating transmission rod 1003.

[0034] In the present utility model, the workpiece 2 is clamped by the active support assembly 6 and the driven support assembly 7. Then, the guide wheel of the beating conduction assembly 10 contacts the belt installation groove of the workpiece 2. Since the beating transmission rod 1003 of the beating conduction assembly 10 is installed through the flexible connection mechanism 1002. Therefore, under the drive of the rotation drive mechanism 5, during the rotation process of the workpiece 2, the end face beating and side face beating of its belt installation groove can be fully transmitted outward through the beating transmission rod 1003. At this time, only a set of dial indicators 12 are needed to detect the end face beating and side face beating of the beating transmission rod 1003 respectively, so that the pulley workpiece can be fixed and stably rotationally driven, and during the process of rotationally driving the workpiece, the beating of the belt installation groove can be synchronously transmitted outward to improve the operation difficulty and detection accuracy of the detection process.

[0035] To prevent excessive mechanical loss to the workpiece, when the existing active support assembly and driven support assembly clamp the workpiece, flexible clamping is mostly used. Since the guide wheel will form a reaction force on the workpiece during the beating transmission process with the workpiece, using flexible clamping will cause the workpiece itself to shake, thus affecting the beating detection accuracy of the workpiece. For this reason, the present utility model makes the following coordinated improvements to the specific structures of the active support assembly and the driven support assembly.

[0036] The active support assembly 6 includes a rigid cylinder 601 rotatably installed on the first mounting plate 3. A corresponding partition 602 is fixedly connected below the top of the rigid cylinder 601. A number of corresponding guide holes are arranged in a circular array on the rigid cylinder 601 above the partition 602. Corresponding jacking rods 603 are respectively movably inserted into the guide holes. A corresponding elastic compression block 604 is fixedly installed in the rigid cylinder 601 above the partition 602, and the top of the elastic compression block 604 is located above the top of the rigid cylinder 601.

[0037] The driven support assembly 7 includes a downward pressing and fixing member 701 rotatably installed on the second mounting plate 4. The downward pressing and fixing member 701 faces the elastic compression block 604, and a cylindrical elastic member 702 with its bottom located below the bottom of the downward pressing and fixing member 701 is fixedly sleeved on the periphery of the downward pressing and fixing member 701.

[0038] The first mounting plate 3 is upward and the second mounting plate 4 is downward, the end faces of the rigid cylinder 601 and the downward pressing fixing member 701 are respectively abutted against the end faces of the workpiece 2, the elastic compression block 604 and the tubular elastic member 702 are respectively compressed to clamp the workpiece 2, and the clamping rod 603 moves outward under the push of the elastic compression block 604 and presses against the inner wall of the workpiece 2.

[0039] After the active support assembly 6 and the driven support assembly 7 cooperate to clamp the workpiece 2, the end faces of the rigid cylinder 601 and the downward pressure fixing member 701 are respectively abutted against the end faces of the workpiece 2 to form a travel limit for the workpiece 2 in the longitudinal direction; and the elastic compression block 604 and the cylindrical elastic member 702 are respectively compressed to clamp the workpiece 2; in addition, the clamping rod 603 moves outward under the push of the elastic compression block 604 and presses against the inner wall of the workpiece 2, so that the travel limit for the workpiece 2 can be formed in the transverse direction. In this way, the workpiece 2 can be fully clamped and fixed, and the workpiece 2 can be limited in the longitudinal and transverse directions without causing excessive mechanical damage to the workpiece 2, so as to ensure that the workpiece 2 does not shake or deflect during the rotation process, so as to ensure that the end face runout and side runout of the workpiece 2 can be transmitted outwardly through the runout transmission rod 1003 with high precision, so as to further ensure the runout detection accuracy.

[0040] The flexible connection mechanism 1002 comprises a group of connection blocks 10021 fixedly connected to the fixed plate 1001 and the vibration transmission rod 1003. The two sides of the connection block 10021 are supported and connected by a group of inclined elastic metal plates 10022. Under the buffering effect of the inclined elastic metal plates 10022, the freedom of movement of the vibration transmission rod 1003 is ensured, thereby ensuring the practical effect of the present invention.

[0041] The first lifting drive mechanism 8 and the second lifting drive mechanism 9 both use lifting drive cylinders. The fixed plate 1001 is driven by a fixed plate drive mechanism 11 fixedly mounted on the frame 1, and the fixed plate drive mechanism 11 uses a screw transmission mechanism. The rotation drive mechanism 5 includes a transmission wheel 501 fixedly connected to the bottom side of the rigid cylinder 601, and the transmission wheel 501 is connected to the output shaft end of the corresponding drive motor 502 through a belt drive. The outer ends of the tightening rods 603 are respectively arranged in a spherical shape.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
