Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to an indexing turntable device. Background Technology

[0002] Indexing turntables are accessory tooling devices that clamp workpieces on a chuck and rotate, index, and position them. They are widely used in automated equipment such as marking machines, dispensing machines, and automatic screw machines. Most existing indexing turntables are cam dividers and motor-driven, which are relatively expensive and have difficulty guaranteeing positioning accuracy. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide an indexing turntable device that can save costs and improve positioning accuracy.

[0004] This utility model is achieved through the following technical solution: an indexing turntable device, comprising a base, a product fixing seat, a turntable, and a positioning component; the turntable is rotatably connected to the base, the product fixing seat is disposed on the turntable, and the positioning component is located between the turntable and the base, comprising a positioning pin and an elastic element, one end of the positioning pin being disposed on the base through the elastic element, and the other end abutting against the turntable, the turntable having a plurality of positioning parts arranged in a ring around its center, the positioning parts cooperating with the positioning pin.

[0005] Compared with existing technologies, the indexing turntable device provided by this utility model improves positioning accuracy by setting a positioning component between the turntable and the base. This component includes a positioning pin and an elastic element. The positioning pin abuts against the turntable under the action of the elastic element. The turntable has several positioning parts arranged in a ring around its center. When the turntable rotates to a certain angle, the positioning pin engages with the positioning parts under the action of the elastic element, rigidly positioning the turntable. Furthermore, this indexing turntable device has a simple structure and reasonable layout, resulting in lower manufacturing costs compared to existing indexing turntables.

[0006] Furthermore, the positioning pin includes a tapered portion and a connecting portion. One end of the connecting portion is disposed on the base via the elastic element, and the other end is connected to the tapered portion. The outer diameter of the tapered portion gradually decreases from the end connected to the connecting portion. The positioning portion mates with the tapered portion. The tapered portion design facilitates the mating of the positioning pin and the positioning portion. Furthermore, even if the positioning pin and the positioning portion wear down, the elastic element eliminates the gap caused by wear, allowing the positioning pin to maintain its mating with the positioning portion. This prevents the gap caused by wear from affecting positioning accuracy.

[0007] Furthermore, the positioning part is a positioning hole; the positioning assembly also includes a positioning sleeve, which is disposed within the positioning hole and has a tapered hole that matches the tapered part. The positioning hole engages with the tapered part through the positioning sleeve. The positioning sleeve prevents the turntable from being worn.

[0008] Furthermore, it also includes a movable rod for disengaging the positioning pin from the positioning part, the positioning pin being connected to the movable rod. The movable rod disengages the positioning pin from the positioning part, thereby unlocking the turntable.

[0009] Furthermore, the positioning component also includes a mounting base disposed on the base, the mounting base having a through-hole extending vertically; the elastic element is disposed within the channel, one end of the positioning pin is slidably disposed within the channel and pressed against the base by the elastic element, the other end extends out of the channel and abuts against the turntable. The channel on the mounting base ensures that the positioning pin moves vertically, improving the stability of the positioning pin's movement.

[0010] Furthermore, the channel is a sliding hole that matches the positioning pin, and the mounting base has a clearance groove communicating with the sliding hole. The movable rod is hinged to the base, and one end passes through the clearance groove and connects to the positioning pin. The channel is designed as a sliding hole, which can radially limit the positioning pin. By pressing the end of the movable rod away from the positioning pin upwards, the positioning pin can be disengaged from the positioning part, which is convenient and effortless.

[0011] Furthermore, the channel is a sliding hole that matches the positioning pin. Two clearance grooves communicating with the sliding hole are respectively provided on both sides of the mounting base, and the positioning pin has a connecting hole. One end of the movable rod is hinged to the base, and the other end passes through the two clearance grooves and the connecting hole. The channel is designed as a sliding hole, which allows for radial positioning of the positioning pin. By pressing down on the end of the movable rod away from the hinge, the positioning pin can be disengaged from the positioning part, which is convenient and effortless.

[0012] Furthermore, the base is provided with a hinge seat, and one end of the movable rod is hinged to the hinge seat. When the positioning pin abuts against the turntable, the movable rod is in a horizontal state. This design reduces the space occupied by the movable rod between the base and the turntable.

[0013] Furthermore, a product fixing seat is provided between each pair of adjacent positioning parts. The product fixing seat includes a first clamping member and a second clamping member. The first clamping member and the second clamping member are disposed opposite to each other and define a clamping space for placing the product. The first clamping member and the second clamping member are used to clamp and fix the product.

[0014] Furthermore, the product mounting base is a motor mounting base. The first clamping member is a clamping block located near the center of the turntable, and the second clamping member is a clamping pin located opposite the clamping block and near the edge of the turntable. The clamping pin and the clamping block define the clamping space. The clamping block has a second clearance groove for the motor shaft to extend out of the clamping space. The motor is clamped and fixed by the clamping block and the clamping pin.

[0015] Furthermore, it also includes a controller and a rotary driver electrically connected to the controller, the rotary driver being disposed on the base, and the turntable being disposed at the output end of the rotary driver. The rotary driver drives the turntable to rotate.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1 to 4As shown, this embodiment provides an indexing turntable device, including a base 10, a turntable 20, a product fixing seat 30, and a positioning component 40; the turntable 20 is rotatably connected to the base 10, the product fixing seat 30 is disposed on the turntable 20, and the positioning component 40 is located between the turntable 20 and the base 10, including a positioning pin 42 and an elastic element 43. One end of the positioning pin 42 is disposed on the base 10 through the elastic element 43, and the other end abuts against the turntable 20. The turntable 20 is provided with a plurality of positioning parts distributed in a ring around its center, and the positioning parts cooperate with the positioning pin 42. A positioning component 40 is provided between the turntable 20 and the base 10. The positioning component 40 includes a positioning pin 42 and an elastic element 43. The positioning pin 42 abuts against the turntable 20 under the action of the elastic element 43. The turntable 20 has several positioning parts arranged in a ring around its center. When the turntable 20 rotates to a certain angle, the positioning pin 42 cooperates with the positioning parts under the action of the elastic element 43 to rigidly position the turntable 20, thereby improving the positioning accuracy. In addition, this indexing turntable device has a simple structure and reasonable layout, and its manufacturing cost is lower than that of existing indexing turntables.

[0024] In this embodiment, the base 10 is a mounting plate. The turntable 20 is located at the center of the mounting plate and is rotatably connected to the center of the mounting plate. Of course, in other alternative embodiments, the base 10 is not limited to a plate structure; it can be a block structure or a pedestal structure. In this embodiment, the cross-sectional shape of the base 10 is rectangular. Of course, in other alternative embodiments, the cross-sectional shape of the base 10 can be circular, elliptical, or a polygon other than a rectangle, or an irregular shape designed according to the actual installation environment. In this embodiment, the turntable 20 is rotatably connected to the base 10 via a bearing. Specifically, the base 10 is fixedly connected to the outer ring of the bearing, and the turntable 20 is fixedly connected to the inner ring of the bearing, thereby achieving a rotatable connection between the turntable 20 and the base 10. Of course, in other alternative embodiments, the base 10 can be provided with a shaft hole, and the bottom of the turntable 20 can be provided with a rotating shaft that matches the shaft hole. The turntable 20 and the base 10 are rotatably connected through the rotational engagement of the rotating shaft and the shaft hole. In this embodiment, the turntable 20 is a circular turntable. Of course, in other alternative implementations, the turntable 20 can be an ellipse or a rectangle, or an irregular shape designed according to the actual installation environment.

[0025] In this embodiment, the positioning part is a positioning hole 21 that penetrates through the turntable 20, and the positioning hole 21 cooperates with the positioning pin 42. Of course, in other alternative embodiments, the positioning part can be a positioning groove provided at the bottom of the turntable 20, and the positioning groove cooperates with the positioning pin 42.

[0026] In this embodiment, the positioning pin 42 includes a connecting portion 421 and a tapered portion 422. One end of the connecting portion 421 is disposed on the base 10 via the elastic member 43, and the other end is connected to the tapered portion 422. The outer diameter of the tapered portion 422 gradually decreases from the end connected to the connecting portion 421. The positioning hole 21 mates with the tapered portion 422. The design of the tapered portion 422 facilitates the mating of the positioning pin 42 with the positioning hole 21. Furthermore, even if the positioning pin 42 and the positioning hole 21 wear down, the elastic member can eliminate the gap caused by wear, allowing the positioning pin 42 to maintain its mating with the positioning hole 21. This prevents the gap caused by wear from affecting positioning accuracy. Of course, in other alternative embodiments, the positioning pin 42 is not limited to a tapered positioning pin; it can also be a cylindrical or prismatic positioning pin. In this embodiment, the end of the tapered portion 422 away from the connecting portion 421 is curved to reduce the contact area between the tapered portion 422 and the turntable 22, thus reducing wear. Of course, in other alternative embodiments, the end of the tapered portion 422 away from the connecting portion 421 is flat. In this embodiment, the tapered portion 422 and the connecting portion 421 are separate designs. The tapered portion 422 and the connecting portion 421 can be detachably connected by fasteners, snaps, screws, or other means. When the tapered portion 422 is severely worn, it can be replaced separately, thereby reducing replacement costs and facilitating replacement. Of course, the tapered portion 422 and the connecting portion 421 can also be connected by welding. Of course, in other alternative embodiments, the tapered portion 422 can also be integrally formed with the connecting portion 421. The tapered portion 422 described in this embodiment can be made of wear-resistant materials such as wear-resistant rubber, wear-resistant stainless steel, or austenitic manganese steel to improve the wear resistance of the tapered portion 422. Of course, in other alternative embodiments, a dense wear-resistant layer can also be coated on the surface of the tapered portion 422.

[0027] In this embodiment, the elastic element 43 is a spring, and a positioning protrusion 4212 is provided at the end of the connecting portion 421 away from the tapered portion 422. One end of the spring is sleeved on the positioning protrusion 4212, and the other end presses against the base 10. Of course, in other alternative embodiments, the elastic element 43 can be made of elastic materials such as rubber, spring steel, or silicone.

[0028] In this embodiment, the positioning component 40 further includes a positioning sleeve 44, which is disposed within the positioning hole 21. Specifically, the positioning sleeve 44 has a tapered hole 441 that matches the tapered portion 422, and the positioning hole 21 engages with the tapered portion 422 through the positioning sleeve 44. The positioning sleeve 44 prevents wear on the positioning hole 21 of the turntable 20. In this embodiment, the positioning sleeve 44 can be detachably mounted on the positioning hole 21 using fasteners, snap-fit ​​devices, etc., allowing for easy replacement after wear. Alternatively, in other alternative embodiments, the positioning sleeve 44 can be fixed to the positioning hole 21 by welding. The positioning sleeve 44 in this embodiment can also be made of wear-resistant materials such as wear-resistant rubber, wear-resistant stainless steel, or austenitic manganese steel. Alternatively, in other alternative embodiments, a dense wear-resistant layer can be coated on the inner surface of the tapered hole 441 of the positioning sleeve 44.

[0029] In this embodiment, the indexing turntable device further includes a movable rod 50 for disengaging the positioning pin 42 from the positioning hole 21, wherein the positioning pin 42 is connected to the movable rod 50. The movable rod 50 disengages the positioning pin 42 from the positioning hole 21, thereby unlocking the turntable 20.

[0030] In this embodiment, the positioning component 40 further includes a mounting base 41 disposed on the base 10. The mounting base 41 has a channel extending vertically through it. The elastic member 43 is disposed within the channel. One end of the positioning pin 42 is slidably disposed within the channel and pressed against the base 10 by the elastic member 43, while the other end extends out of the channel and abuts against the turntable 20. The channel on the mounting base 41 ensures that the positioning pin 42 moves vertically, improving the stability of the positioning pin 42's movement.

[0031] In this embodiment, the channel is a sliding hole 412 that matches the positioning pin 42. The channel is designed as a sliding hole 412 to radially limit the positioning pin 42. Of course, in other alternative embodiments, the channel can be a through groove formed in the mounting base 41, with the positioning pin 42 slidably disposed in the groove. One end of the positioning pin 42 is disposed on the base 10 via an elastic member 43, and the other end extends out of the groove and connects to the turntable 20. The movable rod 50 is connected to the positioning pin 42 through the groove opening via an intermediate connector, or one side of the positioning pin 42 protrudes out of the groove opening and connects to the movable rod 50.

[0032] In some optional embodiments, the mounting base 41 has two clearance grooves 411 on each side that communicate with the sliding hole 412, and the positioning pin 42 has a connecting hole 4211; one end of the movable rod 50 is hinged to the base 10, and the other end passes through the two clearance grooves 411 and the connecting hole 4211. By pressing down on the end of the movable rod 50 away from the hinge, the positioning pin 42 can be disengaged from the positioning sleeve 44, which is convenient and effortless. Of course, in other optional embodiments, the mounting base 41 has clearance grooves 411 that communicate with the sliding hole 412, the movable rod 50 is hinged to the base 10, and one end passes through the clearance groove 411 and is connected to the positioning pin 42. That is, the hinge of the movable rod 50 is located between the two ends of the movable rod 50. By pressing up on the end of the movable rod 50 away from the positioning pin 42, the positioning pin 42 can be disengaged from the positioning sleeve 44, which is convenient and effortless.

[0033] In this embodiment, the mounting base 41 is detachably mounted to the base 10 via fasteners, thereby facilitating the replacement of the positioning pin 42. Of course, the mounting base 41 can be detachably connected to the base 10 via snap-fit, screw connection, or other means, or it can be fixedly connected to the base 10 by welding.

[0034] In this embodiment, the base 10 is provided with a hinge seat 60, and one end of the movable rod 50 is hinged to the hinge seat 60. When the positioning pin 42 abuts against the turntable 20, the movable rod 50 is in a horizontal state. This arrangement reduces the space occupied by the movable rod 50 between the base 10 and the turntable 20, and the horizontal state makes it easier to press.

[0035] In this embodiment, a product fixing seat 30 is provided between each pair of adjacent positioning holes 21. The product fixing seat 30 includes a first clamping member and a second clamping member, which are disposed opposite to each other and define a clamping space for placing the product. The first and second clamping members are used to clamp and fix the product. In this embodiment, there are three positioning holes 21, and correspondingly three product fixing seats 30. Of course, in other alternative embodiments, there can be two, four, or more positioning holes 21, and correspondingly, there can be two, four, or more product fixing seats 30.

[0036] In this embodiment, the product mounting base 30 is a motor mounting base. The first clamping member is a clamping block 31 located near the center of the turntable 20, and the second clamping member is a clamping pin 32 located opposite the clamping block 31 and near the edge of the turntable 20. The clamping pin 32 and the clamping block 31 define the clamping space. The clamping block 31 has a second clearance groove 311 for the motor shaft to extend out of the clamping space. The motor is clamped and fixed by the clamping block 31 and the clamping pin 32. Of course, in other alternative embodiments, the first and second clamping members can be designed according to the specific product structure and are not limited to the structural form of the clamping block 31 and the clamping pin 32.

[0037] In this embodiment, a controller and a rotary driver electrically connected to the controller are also included. The rotary driver is disposed on the base 10, and the turntable 20 is disposed at the output end of the rotary driver. The rotary driver drives the turntable 20 to rotate. In this embodiment, the rotary driver is a drive motor. Of course, in other alternative embodiments, the rotary driver can be a rotary cylinder.

[0038] In some alternative implementations, a pressure sensor may be included, which is electrically connected to the controller. The pressure sensor is disposed between the elastic element 43 and the base 10. When the movable rod 50 drives the positioning pin 42 to move down and disengage from the positioning sleeve 44, the elastic element 43 presses against the pressure sensor. When the pressure detected by the pressure sensor is greater than a set value, it sends a rotation signal to the controller, which controls the drive motor to rotate, thereby realizing automatic control.

[0039] In some optional embodiments, a telescopic actuator electrically connected to the controller is also included, the output end of which is connected to the end of the movable rod 50 away from its hinge. The telescopic actuator drives the movable rod 50, causing the positioning pin 42 to disengage from the positioning sleeve 44. The controller can be electrically connected to equipment used with this indexing turntable device, receiving a signal indicating completion of processing, and then driving the telescopic actuator. The telescopic actuator can be a telescopic cylinder, an electric push rod, etc.
