Technical Field

[0001] The invention relates to the technical field of turrets, and in particular to a power structure of a tool in a turret. Background Art

[0002] The CNC turret is a common metal processing equipment. It has multiple tool stations and can meet the needs of workpiece processing for different tools through the rotation of the tool holder, thereby improving processing efficiency.

[0003] The existing patent with publication number CN108746687A discloses a high-stability power turret, including a seat body, a carrier cavity is arranged through the seat body, a tailstock is arranged through the carrier cavity, a knife disc fixed to the end of the tailstock, and a lifting plate fixed to the tailstock or integrally formed with the tailstock, a static knife seat and a rotating knife seat for clamping a tool are arranged circumferentially on the knife disc, a radial transmission shaft is arranged radially in the inner side of the knife disc to drive the rotating knife seat to rotate, an axial transmission shaft connected to the radial transmission shaft by a helical gear transmission is arranged in the tailstock, the axial transmission shaft is concentric with the knife disc, and a second motor driving the axial transmission shaft to rotate is arranged at the end of the tailstock; a bearing sleeve is sleeved on the axial transmission shaft, one end of the bearing sleeve is fixed to the knife disc, and the other end is rotatably connected to the tailstock; a stepped bushing is sleeved on the outside of the bearing sleeve, and a large-diameter stepped portion of the stepped bushing is provided with a toothed outer edge, and a third motor driving the stepped bushing to rotate by a gear transmission is arranged on the tailstock.

[0004] The above-mentioned prior art solutions have the following defects:

[0005] The second motor is used to provide power for the rotating tool seat, that is, the second motor determines the cutting power of the tool on the rotating tool seat. Generally, the faster the rotation speed of the tool, the higher the quality of the cut surface, but a larger power motor is needed to increase the power of the rotating tool seat, and the power of the motor is usually positively correlated with its volume. However, a third motor is also installed on the tailstock, and the third motor occupies part of the space on the tailstock, which makes it impossible to use a larger motor for the second motor. Therefore, the actual processing quality of the turret is limited. Summary of the invention

[0006] The purpose of the present invention is to provide a power structure of a tool in a turret, wherein a mounting frame provides sufficient installation space for a large-volume power motor, and the power motor is connected to the axial transmission shaft through a synchronous belt, thereby providing sufficient power for the axial transmission shaft to improve the workpiece processing quality.

[0007] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0008] A power structure of a tool in a turret comprises a seat body and an axial transmission shaft arranged in the seat body, a mounting frame is arranged on the outer side of the seat body close to the axial rotating shaft, a power motor is arranged on the mounting frame, a driving pulley is coaxially fixed to the rotating end of the power motor, a driven pulley is arranged at the rotating end of the axial transmission shaft, and a synchronous belt is wound between the driving pulley and the driven pulley.

[0009] By adopting the above technical solution, the mounting frame is used to place the power motor, and the mounting frame is located on the outer side of the left end of the seat body to avoid other motors. The mounting frame provides a larger installation space for a power motor with higher power. At the same time, a driving pulley is coaxially fixed to the rotating end of the power motor, and a synchronous belt is installed on the driving pulley and the driven pulley, thereby achieving the purpose of the power motor providing power for the axial transmission shaft.

[0010] The present invention is further configured as follows: the mounting frame includes a support plate for supporting the power motor and a clamping plate for cooperating with the outer side of the seat body to clamp the power motor; a slideway is provided at one end of the support plate away from the seat body, the slideway extends along the axial direction of the transmission shaft, a sliding rod is slidably inserted in the slideway, the end of the sliding rod away from the seat body is fixedly connected to the clamping plate, and an adjustment component for adjusting the movement of the sliding rod is provided on the support plate.

[0011] By adopting the above technical solution, the power motor is placed on the support plate, and then the clamp is pushed. The cooperation between the slideway and the slide rod enables the clamp to move stably toward the seat body until the power motor is clamped and fixed between the clamp and the seat body, thereby fixing the power motor and ensuring the stability of the power motor in transmitting power to the axial transmission shaft.

[0012] The present invention is further configured as follows: an avoidance groove connected to the slideway is opened on the side of the support plate facing the active pulley, the adjustment component includes a rotating shaft rotatably arranged at one end of the support plate facing the active pulley and a gear coaxially fixed on the rotating shaft, the rotating shaft is perpendicular to the slide bar, the gear part is embedded in the slideway through the avoidance groove, and the slide bar is provided with a tooth groove meshing with the gear along its length direction; a worm gear is coaxially fixed to the lower end of the rotating shaft, and a worm meshing with the worm gear is rotatably arranged at the lower end of the support plate.

[0013] By adopting the above technical solution, the worm is driven to rotate, and then the worm wheel and the gear are synchronously driven, and the cooperation between the gear and the tooth groove enables the slide bar to move in the slideway, thereby realizing the movement and locking of the clamping plate. When the clamping plate moves away from the seat body, it is convenient to replace the power motor. When the clamping plate is close to clamp the power motor, the fixing stability of the power motor is guaranteed, thereby improving the convenience of disassembly and assembly of the power motor.

[0014] The present invention is further configured as follows: a rubber pad is provided on the side of the clamping plate facing the seat body, and the rubber pad is squeezed and fixed between the clamping plate and the seat body.

[0015] By adopting the above technical solution, the power motor is clamped and fixed between the clamping plate and the seat body, and at the same time the rubber pad on the clamping plate is squeezed and deformed. Since the outer side of the power motor is generally uneven, the rubber pad part is embedded and matched with the outer side of the power motor to improve the stability of the fixation of the power motor.

[0016] The present invention is further configured as follows: a fixing frame is arranged on the seat body toward one end of the synchronous belt, a bearing seat is slidingly arranged on the fixing frame along a vertical direction, a tensioning wheel is rotatably arranged on the bearing seat, the axis of the tensioning wheel is parallel to the axis of the axial transmission shaft, and a pushing component is arranged on the fixing frame to push the bearing seat until the tensioning wheel is squeezed onto the outside of the synchronous belt.

[0017] By adopting the above technical solution, when the synchronous belt is installed on the driving pulley and the driven pulley, the bearing seat is pushed to move upward, so that the tensioning wheel squeezes the synchronous belt until the synchronous belt is tensioned, thereby ensuring the stability of power transmission from the power motor to the axial transmission shaft.

[0018] The present invention is further configured as follows: the fixed frame includes a pair of parallel slide rails, the slide rails extend in a vertical direction, the bearing seat is slidably sleeved on the slide rails, the pushing assembly includes a push plate slidably sleeved on the slide rails and a support spring sleeved on the slide rails, the push plate is located below the bearing seat, and both ends of the support spring abut between the push plate and the bearing seat; a screw rod is rotatably arranged on the seat body and located between the slide rails, the screw rod is parallel to the slide rails, and the push plate and the screw rod are threadedly matched.

[0019] By adopting the above technical solution, when the synchronous belt is tensioned, the screw rod is rotated and the push plate moves upward, so that the bearing seat and the tensioning wheel move upward, and during the use of the turret, the axial transmission shaft moves upward and downward, and the support spring is retracted and released to ensure that the tensioning wheel can stably tension the synchronous belt.

[0020] The present invention is further configured as follows: a worm gear 2 is coaxially arranged at the lower end of the screw rod, and the screw rod extends to mesh with the worm gear 2.

[0021] By adopting the above technical solution, the worm is extended to between the seat body and the second worm wheel, and the worm is meshed with the second worm wheel. When the worm is rotated to drive the clamping plate to fix the power motor, the second worm wheel drives the lead screw to rotate, so that the push plate drives the tensioning wheel to squeeze the synchronous belt. Similarly, when replacing the power motor or the synchronous belt, the worm is rotated in the opposite direction to loosen the fixation of the power motor and tighten the synchronous belt, thereby achieving the purpose of facilitating the disassembly and assembly of the power motor on the seat body.

[0022] The present invention is further configured as follows: a prism extends from the lower end of the screw rod, the second worm gear is sleeved on the prism, a retaining ring supporting the second worm gear is coaxially arranged at the lower end of the prism, and the retaining ring is fixed to the lower end of the prism by screws.

[0023] By adopting the above technical solution, the retaining ring is supported on the lower end of the worm gear 2, and the worm gear 2 cooperates with the prism to realize the coaxial synchronous rotation between the worm gear 2 and the lead screw, and the worm gears of different sizes can be replaced synchronously to engage with the worm, so as to have different transmission ratios, thereby ensuring that the driving push plate enables the tensioning wheel to stably tension synchronous belts of different sizes.

[0024] In summary, the beneficial technical effects of the present invention are:

[0025] The mounting frame provides sufficient installation space for the large-volume power motor. The power motor and the axial transmission shaft are connected by a synchronous belt, thereby achieving the purpose of transmitting power from the power motor to the axial transmission shaft.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2As shown, a power structure of a tool in a turret includes a base body 1 and an axial transmission shaft 2 arranged in the base body 1, wherein the base body 1 is a square frame structure, and the side of the base body 1 close to the axial transmission shaft 2 is the left end, and a driven pulley 21 is coaxially fixed at the rear end of the axial transmission shaft 2, and a mounting frame 5 is fixed on the outer side of the left end of the base body 1, and the mounting frame 5 is used to place a power motor 3, and the mounting frame 5 is located on the outer side of the left end of the base body 1 to avoid other motors. The mounting frame 5 provides a larger installation space for a power motor 3 with higher power, and at the same time, a driving pulley 31 is coaxially fixed at the rotating end of the power motor 3, and a synchronous belt 4 is assembled on the driving pulley 31 and the driven pulley 21, thereby achieving the purpose of the power motor 3 providing power for the axial transmission shaft 2.

[0031] The mounting frame 5 includes a horizontally extending support plate 6 and a vertically extending clamping plate 7, the support plate 6 is perpendicular to the left side of the seat body 1, and a slideway 61 is extended toward the seat body 1 at one end of the support plate 6 away from the seat body 1, and the slideway 61 is provided with a pair of slides that are both perpendicular to the left side of the seat body 1, and a slide bar 72 is slidably inserted in the slideway 61, the clamping plate 7 is located on the side of the support plate 6 away from the seat body 1, and the slide bar 72 is fixed to the side of the clamping plate 7 facing the support plate 6, so that the clamping plate 7 is arranged parallel to the left side of the seat body 1, and is arranged in close contact with the side of the clamping plate 7 facing the seat body 1. A rubber pad 71 is placed; the power motor 3 is placed on the support plate 6, and then the clamping plate 7 is pushed. The cooperation between the slide 61 and the slide rod 72 enables the clamping plate 7 to stably move toward the seat body 1 until the power motor 3 is clamped and fixed between the clamping plate 7 and the seat body 1. At the same time, the rubber pad 71 on the clamping plate 7 is squeezed and deformed. Since the outer side of the power motor 3 is generally uneven, the rubber pad 71 is embedded in the outer side of the power motor 3 to fix the power motor 3, thereby ensuring the stability of the power motor 3 in transmitting power to the axial transmission shaft 2.

[0032] The front end of the support plate 6 toward the seat body 1 is the front side, and the two slideways 61 are respectively located at the front and rear sides of the support plate 6. A rotating shaft 8 is rotatably installed at the rear end of the support plate 6. The rotating shaft 8 extends in the vertical direction and is close to the end of the support plate 6 away from the seat body 1. A gear 81 is coaxially fixed to the upper end of the rotating shaft 8, and an avoidance groove 62 for avoiding the rotation of the gear 81 is opened on the support plate 6. The avoidance groove 62 is connected with the slideway 61, and the gear 81 is partially extended into the slideway 61. A tooth groove 73 is opened on the slide bar 72 and on one side facing the gear 81. The tooth groove 73 is arranged at intervals along the axial direction of the slide bar 72.

[0033] When the driving shaft 8 drives the gear 81 to rotate, the cooperation between the gear 81 and the tooth groove 73 makes the slide bar 72 move in the slideway 61. At the same time, the lower end of the shaft 8 is under the support plate 6, and a worm wheel 82 is coaxially fixed at the lower end of the shaft 8. A worm 9 is rotatably installed on the lower side of the support plate 6. The worm 9 is meshed with the worm wheel 82, and a hand wheel is fixedly installed at the end of the worm 9 away from the seat body 1. The worm 9 is driven to rotate by the hand wheel, and then the worm wheel 82, gear 81 and the slide bar 72 are synchronously driven to move, thereby realizing the movement and locking of the splint 7.

[0034] A fixing frame is arranged at the rear end of the seat body 1 and between the power motor 3 and the axial transmission shaft 2. The fixing frame includes a pair of parallel slide rails 10. The slide rails 10 are extended in the vertical direction, and fixing rods vertically fixed to the rear side of the seat body 1 are extended at both ends of the slide rails 10. A bearing seat 11 is arranged on the fixing frame. The bearing seat 11 and the slide rail 10 are slidably fitted. A tensioning shaft is rotatably installed in the bearing seat 11. The tensioning shaft is parallel to the axial transmission shaft 2, and a tensioning wheel 12 is coaxially fixed on the tensioning shaft. When the synchronous belt 4 is installed on the driving pulley 31 and the driven pulley 21, the bearing seat 11 is pushed to move upward, so that the tensioning wheel 12 squeezes the synchronous belt 4 until the synchronous belt 4 is tensioned, thereby ensuring the stability of power transmission from the power motor 3 to the axial transmission shaft 2.

[0035] At the same time, a push plate 13 is slidably installed on the fixed frame, and the push plate 13 is slidably sleeved with the slide rail 10, and a screw rod 15 is rotatably installed at the rear end of the seat body 1 and between the slide rails 10, and the screw rod 15 is threadedly connected with the push plate 13, and is slidably penetrated between the screw rod 15 and the bearing seat 11, and a support spring 14 is also sleeved on the slide rail 10, and the two ends of the support spring 14 are respectively abutted between the bearing seat 11 and the push plate 13; when the synchronous belt 4 is tensioned, the screw rod 15 is rotated, and the push plate 13 moves upward, so that the bearing seat 11 and the tensioning wheel 12 move upward, and during the use of the turret, the axial transmission shaft 2 will move upward and downward, and the support spring 14 is retracted and released to ensure that the tensioning wheel 12 stably tensions the synchronous belt 4.

[0036] A prism 16 is coaxially extended from the lower end of the screw rod 15, and a worm gear 17 is coaxially sleeved on the prism 16, and a retaining ring 18 is coaxially arranged at the lower end of the prism 16, and the retaining ring 18 and the prism 16 are fixed by screws to realize the coaxial synchronous rotation between the worm gear 17 and the screw rod 15; the worm 9 is extended to between the seat body 1 and the worm gear 17, and the worm 9 is meshed with the worm gear 17. When the worm 9 is rotated to drive the clamping plate 7 to fix the power motor 3, the worm gear 17 drives the screw rod 15 to rotate, so that the push plate 13 drives the tensioning wheel 12 to squeeze the synchronous belt 4. Similarly, when replacing the power motor 3 or the synchronous belt 4, the worm 9 is rotated in the opposite direction, thereby loosening the fixation of the power motor 3 and tightening the synchronous belt 4, that is, achieving the purpose of facilitating the disassembly and assembly of the power motor 3 on the seat body 1.

[0037] The implementation principle of this embodiment is:

[0038] The power motor 3 is fixed on the mounting bracket 5 on the left side of the seat body 1. The mounting bracket 5 provides sufficient installation space for the large-volume power motor 3. The power motor 3 is connected to the axial transmission shaft 2 through a synchronous belt 4, thereby achieving the purpose of transmitting power from the power motor 3 to the axial transmission shaft 2.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
