Description

Technical Field

[0001] The invention relates to the field of machine tools, and in particular to a double-axis turntable system. Background Art

[0002] The dual-axis turntable system is often used on the worktable of high-end machine tools to drive the worktable to flip to meet the needs of complex curved surfaces and multi-faceted processing of workpieces, so that the workpiece can be processed in one clamping, reducing the number of working steps and improving processing efficiency.

[0003] However, in the existing dual-axis rotary table system, the height of the worktable is generally designed to be relatively low, as shown in the attached manual. Figure 1 As shown in the figure, the worktable is located at the lowest position in the middle of a pair of swing arms. Although such a design can improve the stability of the turntable system and ensure the processing accuracy, the size of the workpiece to be processed placed on the table top is limited due to the low height of the table top. If the workpiece size is too large, when the worktable drives the table top to rotate around the vertical axis or the support seat drives the worktable and the swing arm to rotate around the horizontal axis, the workpiece is at risk of touching the swing arm, the support seat or the ground, endangering the safety of the machine tool processing. Therefore, the existing dual-axis turntable system generally has the problem of limited processing workpiece size, which limits its scope of application.

[0004] In addition, when processing certain products, in order to ensure processing accuracy, the next process needs to use the hole or surface processed in the previous process as a reference. If the parts to be processed in the previous and next processes are not on the same part of the product's outer wall, it may be necessary to frequently control the workbench to drive the table panel to rotate around its own axis to rotate the processed part on the product's outer wall to an area that is not facing or close to the support seat, such as Figure 1 As shown, face A of a product to be processed is close to the left support seat, and the direction indicated by the arrow is the travel processing direction of the machine tool's cutter head. Obviously, the left support seat will hinder the movement of the cutter head. Therefore, the industry's common practice is to first control the workbench to drive the table panel to rotate 90 degrees or other angles around its own axis, and move face A to a position where the support seat will not hinder the movement of the cutter head. Then the cutter head moves close to face A to process face A. After the previous process of face A is completed, if the surface to be processed in the next process is close to the support seat, it is still necessary to control the workbench to drive the table panel to rotate around its own axis, and move the surface to be processed to a position where the support seat will not hinder the movement of the cutter head, and then process it. Moreover, at this time, face A is likely to come to a position close to the support seat again. If the subsequent next processing process is located at face A If the surface or hole processed by the previous processing step is used as a reference, then before executing this process, it is still necessary to control the workbench to drive the table panel to rotate around its own axis, move the surface A to be processed to a position where the support seat will not hinder the movement of the cutter head, and then perform processing. It can be seen that when processing such products, there is a problem of frequently controlling the workbench to drive the table panel to rotate forward and reverse around its own axis, which greatly delays processing time and affects processing efficiency.

[0024] The present invention proposes a dual-axis turntable system, which connects a support base 1 and a workbench 2 via a connecting arm 3. The length of the connecting arm 3 can be automatically adjusted, thereby adjusting the height of the workbench 2, so that the workbench 2 can flexibly adjust the height of a table panel 21 according to processing needs. The table panel 21 can be lifted to a position higher than the support base 1, thereby meeting the processing needs of workpieces of different types and sizes, expanding the scope of application, and solving the problem that the support base 1 affects the tool head processing operation. There is no need to frequently control the workbench 2 to drive the table panel 21 to rotate forward and reverse around its own axis, thereby saving processing time and improving processing efficiency.

[0025] Specifically, in one embodiment of the invention, Figure 2 As shown, the dual-axis turntable system includes a support seat 1 and a workbench 2, wherein the workbench 2 is located between a pair of support seats 1, and the workbench 2 and the support seat 1 are hingedly connected via a connecting arm 3, and the support seat 1 is fixed, and the height of the workbench 2 can be adjusted by changing the length of the connecting arm 3. It is known that a table panel 21 is provided at the upper end of the workbench 2, and the workbench 2 can drive the table panel 21 to rotate around its own central axis, and the support seat 1 can drive the connecting arm 3 and the workbench 2 to rotate around the horizontal rotation central axis of the support seat 1.

[0026] In this embodiment, if Figure 2-Figure 7 As shown, the connecting arm 3 includes a box body and a screw rod 37. The box body is hingedly connected to the support seat 1. Specifically, as shown Figure 2-Figure 7 As shown, the box body includes a U-shaped plate 32 and a mounting plate 38, the mounting plate 38 is detachably sealed and fixedly connected to the U-shaped plate 32, and the mounting plate 38 is spaced and arranged in parallel with the right end of the U-shaped plate 32, so as to facilitate the rotational installation of the screw barrel 39 between the right end of the U-shaped plate 32 and the mounting plate 38, as shown in FIG. Figure 2-Figure 7As shown, the right end of the U-shaped plate 32 and the mounting plate 38 are both rotatably mounted with a thrust bearing 40, and a screw barrel 39 is rotatably mounted in the box body. The screw barrel 39 is located between the right end of the U-shaped plate 32 and the mounting plate 38. Two thrust bearings 40 are located at both end surfaces of the screw barrel 39 and are coaxially rotatably connected with the screw barrel 39. This design can realize the smooth rotation of the screw barrel 39 in the box body. A gear ring 43 is coaxially fixedly mounted on the screw barrel 39, and the gear ring 43 is meshed with a worm 44, and the worm 44 is rotatably connected to the box body. The worm 44 is transmission-connected to a motor 49, and the motor 49 is fixed to the box body. The two assemblies are fixedly connected, and are designed in this way. The worm 44 is driven to rotate by the motor 49, and the worm 44 drives the gear ring 43 to rotate, and the gear ring 43 drives the screw barrel 39 to rotate. The right end of the U-shaped plate 32 and the mounting plate 38 are both provided with a through hole 41 for the screw rod 37 to pass through. The screw rod 37 passes through the screw barrel 39 and is screwed to the screw barrel 39. The end of the screw rod 37 away from the box body is fixedly installed with a rod seat 36, and the rod seat 36 is hinged to the workbench 2. With this design, after the motor 49 is started, it drives the screw barrel 39 to rotate and move along the axial direction of the screw rod, and then pushes the box body to move relative to the screw rod 37 to adjust the length of the connecting arm 3.

[0027] The connecting arm 3 of this embodiment adopts a small-volume motor 49 to drive the screw barrel 39 to rotate and adjust the length of the connecting arm 3 through the worm 44 and worm gear reduction mechanism. The worm 44 and worm gear reduction mechanism can achieve a large reduction ratio, a large torque output and withstand a high-power load, ensuring that the screw barrel 39 can rotate reliably. At the same time, the worm gear 44 has good transmission stability, does not generate impact loads, and has a reverse self-locking function, ensuring smooth movement, high movement efficiency, and high transmission ratio accuracy. In addition, the small-volume motor 49 has a fast response speed and is easy to accurately control.

[0028] Further, such as Figure 2-Figure 7 As shown, the box body also includes a pair of slide plates 33, which are arranged on both sides of the U-shaped plate 32 and are detachably sealed and fixedly connected to the U-shaped plate 32. This design can prevent the debris and other scraps dropped during the machine tool processing from falling onto the gear ring 43 and the worm 44 to affect the transmission stability, and facilitate the subsequent installation and layout of the driving wheel 47, the oil pan 50, the drainage plate 55 and other components. Figure 6As shown, both ends of the worm 44 are connected to the slide plate 33 for rotation, the motor 49 is fixedly connected to the slide plate 33, the output shaft of the motor 49 is connected to the driving shaft 48 for transmission, the driving shaft 48 is provided with a driving wheel 47, the worm 44 is provided with a driven wheel 46, the driving wheel 47 and the driven wheel 46 are connected for transmission, the wheel diameter of the driving wheel 47 is smaller than the wheel diameter of the driven wheel 46, in this design, a group of reduction mechanisms are provided in front of the reduction mechanism of the worm gear 44, forming a two-stage reduction mechanism to drive the screw barrel 39 to rotate and adjust the length of the connecting arm 3, the two-stage reduction can achieve a larger reduction ratio, a larger torque output and withstand a larger power load, ensure that the screw barrel 39 can rotate reliably under heavy load, and can further reduce the size of the motor 49, the small size of the motor 49 is easy to install, has a fast response speed, and is easy to accurately control.

[0029] Furthermore, in this embodiment, if Figure 6 and Figure 7 As shown, an oil pan 50 and a guide plate 55 are arranged below the mounting plate 38, the screw barrel 39 and the worm 44, the oil pan 50 and the guide plate 55 are fixedly connected to the slide plate 33, the motor 49 is located below the guide plate 55, the oil dripping from the mounting plate 38, the screw barrel 39 and the worm 44 falls on the oil pan 50 or the guide plate 55, the oil on the guide plate 55 is guided by the guide plate 55 to flow into the oil pan 50, such a design can realize the recycling of oil, an oil pump 53 is arranged in the oil pan 50, the outer cover of the oil pump 53 is provided with a filter cover 52 to prevent impurities in the oil from entering the oil pump 53, the oil pump 53 is connected to the oil pipe 54, an oil delivery channel 56 is arranged in the U-shaped plate 32, an oil outlet channel 1 57 is arranged on the hole wall of the through hole 2 41, the oil outlet channel 1 57 is connected to the oil delivery channel 56, and the oil delivery channel 56 is connected with the oil pipe 54, and the lower surface of the U-shaped plate 32 just above the ring gear 43 is provided with an oil outlet passage 2 58, and the oil outlet passage 2 58 is connected with the oil pipe 54. After the oil pump 53 is started, the oil in the oil pan 50 is extracted and enters the oil pipe 54 into the oil pipe 56, and then the oil is sprayed out from the oil outlet passage 1 57 and the oil outlet passage 2 58. The oil sprayed from the oil outlet passage 1 57 is sprayed to the screw rod 37 located at the end of the screw barrel 39 to lubricate and cool the thread at the connection between the screw rod 37 and the screw barrel 39 to avoid thread wear. The oil sprayed from the oil outlet passage 2 58 is sprayed to the ring gear 43, and the oil flows downward along the ring gear 43 to the worm 44 to lubricate and cool the thread at the connection between the ring gear 43 and the worm 44 to avoid thread wear. This design can ensure that the above-mentioned transmission components are well lubricated and heat dissipated, ensure that the connecting arm 3 works stably and efficiently, and help to extend the service life of the connecting arm 3.

[0030] Furthermore, the inner bottom surface of the oil pan 50 and the upper surface of the drainage plate 55 are both inclined surfaces 51. This design facilitates the drainage of oil.

[0031] Furthermore, in this embodiment, an annular groove 42 is provided on the outer circumferential surface of the screw barrel 39, the ring gear 43 is located in the annular groove 42, the worm 44 passes through the annular groove 42, and the oil sprayed from the oil outlet passage 58 is injected into the annular groove 42. This design helps to guide the oil to flow in the annular groove 42, fully acting on the lubrication and cooling of the ring gear 43 and the worm 44. The oil will not flow around on the outer wall of the screw barrel 39, thereby improving the utilization effect of the oil.

[0032] In this embodiment, if Figure 2-Figure 5 As shown, a pair of slides 33 are provided with a through hole 34, and the support seat 1 is provided with at least a pair of limiting plates 11, and a plurality of limiting plates 11 are arranged in parallel at intervals. A pair of slides 33 is located between two adjacent limiting plates 11 and slides closely against the limiting plates 11. The limiting plates 11 are provided with a pin shaft 12 penetrating the through hole 34. With this design, the box body is limited by the limiting plates 11 so that it can only rotate smoothly around the pin shaft 12.

[0033] Furthermore, in this embodiment, if Figure 2-Figure 7 As shown, the box body is slidably sleeved with a slide cylinder 31, the rod seat 36 is fixedly installed in the slide cylinder 31, and the screw rod 37 moves axially relative to the screw cylinder 39 to drive the slide cylinder 31 to slide on the box body. Figure 2 As shown, at least one pair of limit plates 22 are provided on both sides of the workbench 2, and a plurality of limit plates 22 are arranged in parallel at intervals. The slide 31 is located between two adjacent limit plates 22 and slides closely against the limit plates 22. The limit plates 22 are provided with pin shafts 23 passing through the slide 31. With this design, the slide 31 is limited by the limit plates 22 so that it can only rotate smoothly around the pin shafts 23.

[0034] The dual-axis turntable system of this embodiment reliably limits the connecting arm 3 through the limiting plate 1 11 and the limiting plate 2 22, so that the workbench 2 can be raised and lowered smoothly.

[0035] In this embodiment, if Figure 6 and Figure 7As shown, the U-shaped plate 32 slides closely against the inner top and bottom surfaces of the slide 31, and a pair of slide plates 33 slide closely against the inner wall of the slide 31. The end of the slide 31 away from the box body is detachably sealed and fixedly installed with a blocking plate 35, and the rod seat 36 is fixedly connected to the blocking plate 35; one end of the oil delivery channel 56 is connected to the oil delivery pipe 54, and the other end of the oil delivery channel 56 is connected to the inside of the slide 31. In this design, the oil sprayed from the other end of the oil delivery channel 56 falls on the screw rod 37 in the slide 31 to lubricate the screw rod 37, and the oil dripping from the subsequent screw rod 37 falls into the slide 31 to lubricate the connection between the box body and the slide 31, thereby ensuring that the box body and the slide 31 slide smoothly. In addition, the setting of the slide 31 can prevent debris and other scraps that fall during the machine tool processing of the workpiece from falling on the screw rod 37 and affecting the transmission stability.

[0036] Of course, in other embodiments, the other end of the oil delivery passage 56 may be sealed with a sealing plug 59 to prevent oil from flowing out of the other end of the oil delivery passage 56 . This is applicable to embodiments in which the slide cylinder 31 is not provided.

[0037] During the operation of the dual-axis turntable system of this embodiment, generally, the position of the worktable 2 is as follows: Figure 2 As shown, no adjustment is made. This position is consistent with the position of the workbench 2 in the existing dual-axis turntable system. However, if the workpiece product to be processed fixed on the table panel 21 is large in size or the processing technology is complicated, resulting in the problem of frequently controlling the workbench 2 to drive the table panel 21 to rotate forward and reverse around its own axis during processing, the motor 49 can be controlled to drive the screw barrel 39 to rotate. The rotation of the screw barrel 39 drives the box body to move axially along the screw rod 37 to adjust the length of the connecting arm 3, while the support seat 1 is fixed. Therefore, after the length of the connecting arm 3 changes, it drives the workbench 2 to rise and fall. When the connecting arm 3 rotates a certain angle around the pin shaft, the height of the table panel 21 from the ground is higher than the support seat 1. At this moment, the workbench 2 drives the table panel 21 to rotate around its own central axis without the problem of the workpiece product colliding with the support seat 1, so there is no need to control the workbench 2 to drive the table panel 21 to rotate around its own central axis to adjust the orientation of the workpiece processing surface before processing the workpiece product. Moreover, when the height of the table panel 21 from the ground is higher than the support seat 1, the support seat 1 drives the table panel 21 to rotate around the horizontal axis of the support seat 1 within a certain angle range (for example Figure 2 The table panel 21 shown rotates 90 degrees from the horizontal position shown in the figure to the vertical position around the horizontal rotation axis of the support seat 1. There will be no problem of the workpiece product colliding with the support seat 1. Therefore, during the process of processing the workpiece product, there is no need to frequently control the workbench 2 to drive the table panel 21 to rotate forward and reverse around its own axis, which saves processing time, improves processing efficiency, meets the processing needs of workpieces of different types and sizes, expands the scope of application, and solves the problem of the support seat 1 affecting the tool head processing operation.

[0038] The dual-axis turntable system of the present embodiment adopts a small motor to drive the screw barrel to rotate and adjust the length of the connecting arm 3 through a two-stage reduction mechanism. The small motor is small in size and can be easily placed in the box body. Moreover, the small motor has a fast response speed. Compared with the structural design form of directly adopting a large-volume linear motor or cylinder or hydraulic cylinder to adjust the length of the connecting arm 3, the present embodiment adopts a small motor to drive the screw barrel to rotate and adjust the length of the connecting arm 3 through a two-stage reduction mechanism, which is easy to accurately control the displacement of the workbench, and can accurately lift the workbench to the target position, so that the dual-axis turntable system can accurately grasp the real-time coordinates of the workbench and ensure the subsequent machine tool processing accuracy of the workpiece product. However, the large-volume linear motor or cylinder or hydraulic cylinder has poor control accuracy and cannot accurately lift the workbench to the target position, so the dual-axis turntable system cannot accurately grasp the real-time coordinates of the workbench and cannot ensure the subsequent machine tool processing accuracy of the workpiece product.

[0039] It is well known that various sensors are also provided on the existing dual-axis turntable system for the purpose of detecting the position coordinates of the table panel 21 in real time, and then transmitting the detection information to the machine tool. The machine tool subsequently sets the travel direction and angle of the tool head according to the position coordinate information of the table panel 21 to perform precise processing on the workpiece product. Specifically in this embodiment, in order to accurately obtain the height position coordinates of the table panel 21, a rotation angle sensor can be set on the motor 49, and the real-time height position of the table panel 21 can be accurately calculated by detecting the rotation angle of the motor 49.
