Description

Technical Field

[0001] This utility model relates to a support and reinforcement mechanism for a workpiece rotation drive device, which can simultaneously form support and reinforcement at the mounting hole of the workpiece during the rotatable clamping process, thereby effectively ensuring the overall clamping effect of the workpiece. Background Technology

[0002] Existing workpieces, such as pulleys, often require surface grooving equipment to machine grooves on the surface of a blank with a central mounting hole. Existing surface grooving equipment typically includes a workpiece rotation drive for rotating the blank workpiece and a spinning wheel mechanism for spinning the grooves onto the workpiece surface.

[0003] Most existing workpiece surface groove processing equipment uses a workpiece rotation drive device that includes a rotating base rotatably mounted on the bottom side of the frame and a lifting seat that can be raised and lowered on the top side of the frame. A lifting cylinder drives the lifting seat downwards to longitudinally and rotatably clamp the workpiece blank between the lifting seat and the rotating base. Then, a corresponding synchronous drive mechanism drives the rotating base or the lifting seat to rotate. Because the workpiece blank has a mounting hole in the middle, during longitudinal rotation and clamping, if the clamping force is too low, the workpiece is prone to positional displacement during the spinning process; if the clamping force is too high, it can easily cause mechanical damage to the clamping end of the workpiece, which is quite troublesome.

[0004] Therefore, the research objective of this utility model is to design a support and reinforcement mechanism for a workpiece rotation drive device that can simultaneously provide support and reinforcement at the mounting holes of the workpiece during the rotatable clamping process, thereby effectively ensuring the overall clamping effect of the workpiece. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a workpiece rotation drive device for workpiece surface groove processing equipment, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A support and reinforcement mechanism for a workpiece rotation drive device includes:

[0008] The clamping mechanism includes a rotating base rotatably mounted on a frame, and a corresponding drive cylinder is fixedly mounted on the frame above the rotating base. The piston rod end of the drive cylinder is arranged downward and a corresponding lifting seat is rotatably mounted on it.

[0009] A fixed cylinder is fixed to the bottom side of the lifting seat. The outer periphery of the fixed cylinder is provided with several corresponding arc-shaped baffles at equal intervals. A set of corresponding connecting rods are fixed to the arc-shaped baffles inward from high to low. The connecting rods are movably inserted into the inner side of the fixed cylinder. The inner ends of the set of connecting rods are respectively fixed with corresponding sliding rods in an inverted T shape.

[0010] A drive shaft is movably inserted into the fixed cylinder. The top of the drive shaft is fixedly connected to the bottom side of the lifting seat by a helical spring. The outer side of the drive shaft is provided with multiple inverted T-shaped grooves for sliding connection of the slide rod. The lifting seat descends to its position to clamp the workpiece between the lifting seat and the rotating base. The arc-shaped push plate moves outward and presses against the inner wall of the workpiece under the drive of the inverted T-shaped grooves on the drive shaft.

[0011] The bottom of the arc-shaped push plate and the drive shaft extend to the lower side of the bottom end of the fixed cylinder. Several fixed blocks located inside the arc-shaped push plate are spaced apart on the rotating base. Corresponding swing rods are oscillatingly mounted on the fixed blocks. The lifting seat descends to its position to fix the workpiece between the lifting seat and the rotating base. The bottom end of the fixed cylinder presses down on the inner end of the swing rod. The outer end of the swing rod is fixedly pressed against the inner side of the corresponding arc-shaped push plate.

[0012] The outer ends of the swing rods are respectively fixed with arc-shaped rods that abut against the lower side of the arc-shaped push plate.

[0013] The top part of the arc-shaped push plate is respectively in an inverted L shape and has a corresponding buffer plate fixed outward. The buffer plate is made of rubber material.

[0014] The lifting seat has an integrally formed, downwardly oriented mounting platform for connecting the fixed cylinder. The outer edge of the mounting platform is located outside the fixed cylinder. The lifting seat descends and presses against the upper side of the buffer plate. The buffer plate is fixed in a compressed state between the lifting seat and the top of the workpiece. The outer edge of the mounting platform forms a travel limit on the inner side of the compressed and deformed buffer plate.

[0015] The bottom side of the fixed cylinder is provided with a corresponding guide flange, and the drive shaft is movably inserted into the guide flange. The upper side of the drive shaft is spaced apart from the fixed cylinder.

[0016] The rotating base has an integrally formed, upward-facing push-blocking frustum in the middle for blocking the drive shaft, and the fixing blocks are respectively disposed on the rotating base outside the push-blocking frustum.

[0017] Advantages of this utility model:

[0018] 1) This utility model adds a fixed cylinder, and then a number of arc-shaped push plates are movably arranged on the periphery of the fixed cylinder. The inverted T-shaped groove on the drive shaft drives the sliding rods inclined and fixed to the inner side of the arc-shaped push plates. Thus, when the lifting seat descends to its position to clamp the workpiece between the lifting seat and the rotating base, the arc-shaped push plates simultaneously move outward and press against the inner wall of the workpiece's hole. This allows for simultaneous support and reinforcement at the workpiece's mounting hole during the rotatable clamping process, effectively ensuring the overall clamping effect of the workpiece.

[0019] 2) Because the drive shaft needs to be equipped with an inverted T-shaped groove to drive the sliding rod mounted on the arc-shaped push plate, the connecting rod and sliding rod cannot be installed at the bottom of the arc-shaped push plate due to the travel limitations between the components, resulting in a lack of necessary support at the bottom of the arc-shaped push plate. Therefore, this invention further provides several fixed blocks spaced apart on the rotating base, located inside the arc-shaped push plate. Each fixed block has a corresponding swing rod that can be oscillatingly mounted. When the lifting seat descends to its position to fix the workpiece between the lifting seat and the rotating base, the bottom end of the fixed cylinder presses down on the inner end of the swing rod, causing the outer end of the swing rod to be fixedly pressed against the bottom of the inner wall of the arc-shaped push plate. This effectively provides reinforced support to the bottom of each arc-shaped push plate, thus effectively ensuring the stability of the bottom support of the arc-shaped push plate.

[0020] 3) The top part of the arc-shaped push plate of this utility model is respectively inverted L-shaped and fixed to the corresponding buffer pressure plate. The middle part of the lifting seat is integrally formed and downwardly provided with a mounting round platform for connecting the fixed cylinder. The outer edge of the mounting round platform is located outside the fixed cylinder. When the lifting seat descends and presses against the upper side of the buffer pressure plate, the outer edge of the mounting round platform forms a stroke limit on the inner side of the compressed and deformed buffer pressure plate, so as to ensure that the buffer pressure plate can be more stably fixed in a compressed state between the lifting seat and the top part of the workpiece, thereby helping to improve the clamping effect of the workpiece.

Detailed Implementation

[0028] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0029] refer to Figure 1-6 A support and reinforcement mechanism for a workpiece rotation drive device, comprising:

[0030] The clamping mechanism 1 includes a rotating base 101 rotatably mounted on a frame 2. A corresponding drive cylinder 102 is fixedly mounted on the frame 2 above the rotating base 101. The piston rod end of the drive cylinder 102 is set downward and a corresponding lifting seat 103 is rotatably mounted on it.

[0031] A fixed cylinder 3 is fixed to the bottom side of the lifting seat 103. Several corresponding arc-shaped baffle plates 4 are movably arranged at equal intervals around the periphery of the fixed cylinder 3. A set of corresponding connecting rods 5 are fixedly connected to the arc-shaped baffle plates 4 inward from high to low. The connecting rods 5 are movably inserted into the inner side of the fixed cylinder 3. The inner ends of the set of connecting rods are respectively inclinedly fixed with corresponding sliding rods 6 in an inverted T shape.

[0032] The drive shaft 7 is movably inserted into the fixed cylinder 3. The top of the drive shaft 7 is fixedly connected to the bottom side of the lifting seat 103 by a helical spring 8. The outer side of the drive shaft 7 is provided with a plurality of inverted T-shaped grooves 701 for sliding connection of the slide rod 6. The lifting seat 103 descends to its position to clamp the workpiece 9 between the lifting seat 103 and the rotating base 101. The arc-shaped push plate 4 moves outward and presses against the inner wall of the workpiece 9 under the drive of the inverted T-shaped grooves 701 on the drive shaft 7.

[0033] This invention adds a fixed cylinder 3, and then movably arranges several arc-shaped baffle plates 4 around the periphery of the fixed cylinder 3. The inverted T-shaped groove 701 on the drive shaft 7 drives the sliding rod 6, which is inclined and fixed to the inner side of the arc-shaped baffle plates 4. Thus, when the lifting seat 103 descends to its position to clamp the workpiece 9 between the lifting seat 103 and the rotating base 101, the arc-shaped baffle plates 4 simultaneously move outward and press against the inner wall of the workpiece 9. This allows for simultaneous support and reinforcement at the mounting hole of the workpiece 9 during the rotatable clamping process, effectively ensuring the overall clamping effect of the workpiece 9.

[0034] The bottom of the arc-shaped push plate 4 and the drive shaft 7 extend to the lower side of the bottom end of the fixed cylinder 3. A plurality of fixed blocks 10 located inside the arc-shaped push plate 4 are spaced apart on the rotating base 101. Corresponding swing rods 11 are oscillatingly mounted on each fixed block 10. The lifting seat 103 descends to its designated position to fix the workpiece 9 between the lifting seat 103 and the rotating base 101. The bottom end of the fixed cylinder 3 presses down on the inner end of the swing rod 11, and the outer end of the swing rod 11 is fixedly pressed against the inner side of the corresponding arc-shaped push plate 4. Arc-shaped rods 12, which abut against the lower side of the arc-shaped push plate 4, are fixed to the outer end of each swing rod 11.

[0035] Because the drive shaft 7 needs to be equipped with an inverted T-shaped groove 701 to drive the slide rod 6 installed on the arc-shaped push plate 4, the connecting rod 5 and the slide rod 6 cannot be set at the bottom of the arc-shaped push plate 4 due to the travel limitation between the components, resulting in the lack of necessary support at the bottom of the arc-shaped push plate 4. To this end, the present invention further provides several fixed blocks 10 located inside the arc-shaped push plate 4 at intervals on the rotating base 101, and each fixed block 10 is swayably mounted with a corresponding swing rod 11. When the lifting seat 103 descends to the position to fix the workpiece 9 between the lifting seat 103 and the rotating base 101, the bottom end of the fixed cylinder 3 presses down on the inner end of the swing rod 11, so that the outer end of the swing rod 11 is fixedly pressed against the bottom side of the inner wall of the arc-shaped push plate 4, thereby effectively forming a reinforced support for the bottom side of each arc-shaped push plate 4. Therefore, it can effectively ensure the stability of the bottom support of the arc-shaped push plate 4.

[0036] The top part of the arc-shaped push plate 4 is respectively in an inverted L shape and has a corresponding buffer plate 13 fixedly connected to it outward. The buffer plate 13 is made of rubber material.

[0037] The lifting seat 103 has an integrally formed, downward-facing mounting frustum 14 for connecting to the fixed cylinder 3. The outer edge of the mounting frustum 14 is located outside the fixed cylinder 3. The lifting seat 103 descends and presses against the upper side of the buffer plate 13. The buffer plate 13 is fixed in a compressed state between the lifting seat 103 and the top end of the workpiece 9. The outer edge of the mounting frustum 14 forms a travel limit on the inner side of the compressed and deformed buffer plate 13. This ensures that the buffer plate 13 can be more stably fixed in a compressed state between the lifting seat 103 and the top end of the workpiece 9, thereby improving the clamping effect on the workpiece 9.

[0038] The bottom side of the fixed cylinder 3 is provided with a corresponding guide flange 15, and the drive shaft 7 is movably inserted into the guide flange 15. The upper side of the drive shaft 7 is spaced apart from the fixed cylinder 3.

[0039] The rotating base 101 is integrally formed in the middle and has an upwardly arranged push-blocking frustum 16 for blocking the drive shaft 7. The fixing blocks 10 are respectively arranged on the rotating base 101 outside the push-blocking frustum 16.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
