Description

Technical Field

[0001] This application relates to the field of milling and turning machine technology, and more particularly to a milling and turning machine. Background Technology

[0002] A milling-turning machine, also known as a milling-turning composite machining center, is valued for its ability to "complete all machining in one setup." It is no longer a single-function machine tool capable only of turning or milling, but rather integrates multiple processes such as turning, milling, drilling, boring, tapping, and even gear making. When machining long-shaft workpieces using a milling-turning machine, a tailstock is installed on the opposite side of the spindle system to provide an auxiliary, rotatable support point and counteract the effects of cutting forces. The tailstock of a milling-turning machine typically includes a guide rail, a slide, and a tailstock body. The guide rail is fixedly mounted on the machine's base, the slide slides on the guide rail, and the tailstock body is fixedly mounted on the upper end of the slide.

[0003] During the tailstock installation process, a lifting device is needed to lift the tailstock body, and then place the tailstock on the slide. The bolt holes of the tailstock body are aligned with the mounting holes of the slide by manual adjustment, and finally fixed with fixing bolts. However, after the tailstock body is placed, it is difficult to ensure that the bolt holes of the tailstock body and the mounting holes of the slide are accurately aligned. Due to the large weight of the tailstock body, the subsequent adjustment process is difficult for the staff. Furthermore, due to production errors, after the tailstock body is installed on the slide, the axis of the tailstock body is not on the same straight line as the axis of the main spindle system. At this time, it is necessary to adjust the position of the tailstock body axis by using shims or scraping the bottom of the tailstock body, which results in extremely low efficiency in adjusting the axis of the tailstock body. Summary of the Invention

[0004] This application proposes a milling and turning machine that has the advantages of easy adjustment of the position of the bolt holes and the center position of the tailstock body, thereby solving the problem of low adjustment efficiency of the bolt holes and the center position of the tailstock body due to the large mass of the tailstock body during installation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a milling and turning machine, comprising a base, a housing, a spindle system, a slide, a tool system, a tailstock, and a control system. The tailstock includes a guide rail, a slide, a main body, and fixing bolts. The slide has several mounting grooves, each containing: a wire threaded sleeve threaded into the mounting groove, with a floating groove at its bottom end; a floating ring slidably mounted in the floating groove; and several balls movably embedded in the top of the floating ring and protruding from the upper end face of the wire threaded sleeve. The main body has several bolt holes at its bottom end. When the main body is fixed to the slide, the bottom end of the fixing bolt is inserted into the bolt hole and threadedly connected to the inner wall of the wire threaded sleeve.

[0006] Furthermore, the bottom end of the floating ring extends out of the floating groove, and the bottom end of the floating ring is slidably and sealed to the inner wall of the mounting groove. The mounting groove at the bottom end of the floating ring is filled with transmission fluid, which supports the floating ring. The side wall of the slide is provided with a buffering mechanism to buffer the transmission fluid.

[0007] Furthermore, a hexagonal head is fixedly fitted at the top of the side wall of the wire thread sleeve, and the upper end face of the hexagonal head is flush with the upper end face of the wire thread sleeve.

[0008] Furthermore, the external thread of the wire thread insert is opposite in direction to the internal thread of the wire thread insert.

[0009] Furthermore, the mounting groove is stepped with a larger diameter in the middle and smaller diameters at both ends, and a limiting ring is fixedly fitted in the middle of the wire thread sleeve, with the limiting ring positioned at the position with the larger diameter of the mounting groove.

[0010] Furthermore, the buffer mechanism includes: a plurality of buffer tubes fixedly installed on the side wall of the slide, each buffer tube being connected to the bottom end of one of the mounting slots; a support spring fixedly connected to the top end of the inner wall of the buffer tube; and a pressing block fixedly connected to the other end of the support spring and slidably sealed inside the buffer tube.

[0011] Furthermore, the support spring is always in a compressed state.

[0012] Furthermore, an anti-rotation strip is fixedly installed on the side wall of the floating ring extending from the floating groove. The anti-rotation strip is embedded in the inner wall of the mounting groove and can slide along the axial direction of the floating ring in the mounting groove.

[0013] Furthermore, the slide block is provided with a sealing mechanism for sealing the buffer tubes. The sealing mechanism includes: a slide groove opened in the slide block and passing through the communication points between several buffer tubes and the mounting groove; an elastic block installed at one end of the slide groove; a sliding plate, which is slidably and sealingly installed at the other end of the slide groove, and the sliding plate has several connecting holes; and a drive screw threaded to the side wall of the slide block, with its end abutting against the end of the sliding plate away from the elastic block.

[0014] Furthermore, the buffer tube has several equidistant scale lines engraved on its side wall, and the diameter of the buffer tube is smaller than the diameter of the mounting groove.

[0015] This application has the following beneficial effects:

[0016] 1. The milling and turning machine provided in this application, after the main body is placed, makes rolling contact with the ball bearings in the mounting groove of the slide, changing sliding friction to rolling friction, thereby reducing the friction between the main body and the slide, facilitating the adjustment of the main body position, and thus solving the problem that the bolt hole position is difficult to adjust due to the large mass of the main body during installation.

[0017] 2. The milling and turning machine provided in this application allows for the adjustment of the height of the four corners of the main body by twisting the hexagonal head and the wire thread sleeve after the main body is fixedly installed with the wire thread sleeve. This facilitates the adjustment of the height position of the main body and enables simple adjustment of the main body axis, thereby improving the efficiency of the main body axis adjustment.

[0018] 3. The milling and turning machine provided in this application adjusts the height of the four corners of the main body by twisting the hexagonal head and the wire thread sleeve. The rotating hexagonal head intermittently squeezes the balls, causing the balls and the floating ring to reciprocate along the axial direction of the wire thread sleeve. By adjusting the height of the hexagonal head and the wire thread sleeve differently each time, the floating ring squeezes different amounts of transmission fluid into the buffer tube below. This facilitates intuitive and uniform adjustment of the height of the four corners of the main body, preventing uneven adjustment of the four corners or excessive adjustment of a certain corner from causing the main body to shift or twist.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figures 1-7 A milling and turning machine includes a base 1, a housing 2, a spindle system 3, a slide 4, a tool system 5, a tailstock 6, and a control system 7. The housing 2 is fixedly installed at the edge of the top of the base 1. The spindle system 3 is fixedly installed on one side of the top of the base 1. The slide 4 is fixedly connected to the side wall of the housing of the spindle system 3 and is located directly above the base 1. The tool system 5 is fixedly installed on the output shaft of the slide 4. The tailstock 6 is provided on the upper end face of the base 1 and opposite to the spindle system 3. The control system 7 is fixedly installed on the outer wall of the housing 2. The control system 7 is used to control the operation of the entire device.

[0031] The tailstock 6 includes a guide rail 61, a slide block 62, a main body 63, and a fixing bolt 64. The guide rail 61 is fixedly installed on the upper end face of the base 1, and the guide rail 61 is parallel to the axis of the spindle system 3 in the length direction. The slide block 62 is slidably installed on the guide rail 61. The slide block 62 has several mounting grooves 621 arranged in an array. A wire thread sleeve 622 is threaded into the mounting groove 621. A floating groove 625 is opened at the bottom end of the wire thread sleeve 622. A floating ring 626 is slidably installed in the floating groove 625. The bottom end of the floating ring 626 extends out of the floating groove 625, and the bottom end of the floating ring 626 is flush with the mounting groove. The inner wall of 621 is connected by a sliding seal. The mounting groove 621 at the bottom of the floating ring 626 is filled with transmission fluid, which supports the floating ring 626. The side wall of the slide 62 is provided with a buffer mechanism 9 to buffer the transmission fluid. The top of the floating ring 626 is movably embedded with a number of balls 627 arranged in a ring array, and the balls 627 protrude from the upper end face of the wire thread sleeve 622. The bottom end of the main body 63 is provided with a number of bolt holes 631 arranged in an array. When the main body 63 is fixed to the slide 62, the bottom end of the fixing bolt 64 is inserted into the bolt hole 631 and threadedly connected to the inner wall of the wire thread sleeve 622.

[0032] A hexagonal head 624 is fixedly fitted at the top of the side wall of the wire thread insert 622, and the upper end face of the hexagonal head 624 is flush with the upper end face of the wire thread insert 622. After the main body 63 and the wire thread insert 622 are fixedly installed by the fixing bolt 64, the wire thread insert 622 and the fixing bolt 64 can be rotated by rotating the hexagonal head 624, thereby adjusting the position of the wire thread insert 622 in the mounting groove 621. This facilitates the adjustment of the length of the wire thread insert 622 extending out of the mounting groove 621, thereby making it easy to adjust the axis of the main body 63 and improving the efficiency of the axis adjustment of the main body 63.

[0033] The external thread of the wire thread insert 622 is opposite to the internal thread of the wire thread insert 622. After the main body 63 and the wire thread insert 622 are fixedly installed by the fixing bolt 64, the wire thread insert 622 can be rotated by continuing to turn the fixing bolt 64, so that the wire thread insert 622 moves to the outside of the mounting groove 621. The position of the wire thread insert 622 can be adjusted by turning the fixing bolt 64, making the adjustment of the wire thread insert 622 more convenient.

[0034] The mounting groove 621 is stepped, with a larger diameter in the middle and smaller diameters at both ends. A limiting ring 623 is fixedly fitted in the middle of the wire thread sleeve 622, and the limiting ring 623 is located at the position with the larger diameter of the mounting groove 621. The axial length of the limiting ring 623 is less than the axial length of the larger diameter position of the mounting groove 621. After the main body 63 and the wire thread sleeve 622 are fixedly installed, when the length of the wire thread sleeve 622 extending out of the mounting groove 621 is adjusted, the limiting ring 623 limits the length of the wire thread sleeve 622 extending out, preventing the wire thread sleeve 622 from sliding out of the mounting groove 621.

[0035] The buffer mechanism 9 includes a buffer tube 91, a support spring 92, and a pressure block 93. Several buffer tubes 91 are fixedly installed on the side wall of the slide 62, and each buffer tube 91 is connected to the bottom end of one of the mounting slots 621. A support spring 92 is fixedly connected to the top end of the inner wall of the buffer tube 91, and a pressure block 93 is fixedly connected to the bottom end of the support spring 92. The pressure block 93 is slidably and sealingly installed inside the buffer tube 91, and the buffer tube 91 at the bottom end of the pressure block 93 is filled with transmission fluid. The support spring 92 is always in a compressed state. When the main body 63 is not placed on the upper end of the slide block 62, the ball 627 and the floating ring 626 are not squeezed by external force. The elastic force of the compressed support spring 92 supports the pressure block 93, which pushes the transmission fluid at the lower end. This causes the transmission fluid to lift the bottom end of the floating ring 626 through the buffer tube 91 and the guide rail 61, ensuring that the ball 627 at the top of the floating ring 626 is in a state that protrudes from the upper end surface of the wire thread sleeve 622.

[0036] An anti-rotation strip is fixedly installed on the side wall of the floating ring 626 extending out of the floating groove 625. The anti-rotation strip is embedded in the inner wall of the mounting groove 621 and can slide along the axial direction of the mounting groove 621 with the floating ring 626. The anti-rotation strip is used to prevent the floating ring 626 and the ball 627 from rotating around the axis of the mounting groove 621. When the wire thread sleeve 622 rotates, it ensures that the wire thread sleeve 622 can squeeze the ball 627, so that the ball 627 and the floating ring 626 reciprocate in the axial direction.

[0037] The slide block 62 is equipped with a sealing mechanism for sealing the buffer tubes 91. The sealing mechanism includes a slide groove 81, an elastic block 82, a sliding plate 83, and a drive screw 84. The slide groove 81 is formed inside the slide block 62 and passes through the communication points between several buffer tubes 91 and the mounting groove 621. An elastic block 82 is installed at one end of the slide groove 81, and a sliding plate 83 is slidably and sealingly installed at the other end of the slide groove 81. One end of the sliding plate 83 is in close contact with the elastic block 82, and the other end of the sliding plate 83 is in close contact with the inner wall of the end of the slide groove 81. Several connecting holes 831 are formed on the sliding plate 83. A drive screw 84 is threadedly connected to the side wall of the slide block 62, and the end of the drive screw 84 abuts against the end of the sliding plate 83 away from the elastic block 82. When the main body 63 is not placed on the upper end of the slide block 62, the ball 627... When the floating ring 626 is not subjected to external pressure, the ball 627 at the top of the floating ring 626 protrudes from the upper end face of the wire thread sleeve 622. At this time, the drive screw 84 has no pressure on the slide plate 83, and the buffer tube 91 is blocked by the slide plate 83 (i.e., the buffer tube 91 cannot be connected through the connecting hole 831). When the main body 63 is placed and the main body 63 presses against the ball 627 and the floating ring 626, the transmission fluid at the bottom of the floating ring 626 cannot be discharged from the buffer tube 91, ensuring that the lower end face of the main body 63 and the ball 627 are in a rolling friction state. At this time, moving the main body 63 reduces the friction between the main body 63 and the upper end face of the slide 62, making it easier to adjust the position of the main body 63, thereby solving the problem that the position of the bolt hole 631 is difficult to adjust due to the large mass of the main body 63 during installation.

[0038] The side wall of the buffer tube 91 is engraved with several equidistant scale lines 911. The diameter of the buffer tube 91 is much smaller than the diameter of the mounting groove 621. After adjusting the position of the main body 63, the drive screw 84 is turned to press the slide plate 83, thereby connecting the connecting hole 831 with the buffer tube 91. At this time, the gravity of the main body 63 presses the ball 627 and the floating ring 626, making the upper end face of the ball 627 flush with the upper end face of the wire thread sleeve 622. Then, through... The fixing bolt 64 secures the main body 63 and the wire thread sleeve 622. When the hexagonal head 624 is turned to adjust the length of the wire thread sleeve 622 extending out of the mounting groove 621, each turn of the hexagonal head 624 and the wire thread sleeve 622 causes the wire thread sleeve 622 to squeeze the ball 627, causing the ball 627 and the floating ring 626 to move downwards. This causes the floating ring 626 to squeeze the transmission fluid at its lower end, allowing the transmission fluid to enter the buffer tube 91 and push the pressure block 93 upwards. When the next ball bearing 627 protrudes from the upper surface of the wire thread sleeve 622, the support spring 92 pushes the pressure block 93, which in turn pushes the transmission fluid, pushing the floating ring 626 and the ball bearing 627 upwards. Each time the ball bearing 627 passes the protruding position, the transmission fluid in the buffer tube 91 floats up and down once. By observing the number of times the pressure block 93 in the buffer tube 91 floats, it is easy to intuitively adjust the extension length of several wire thread sleeves 622 each time. Furthermore, during the rotation of the wire thread sleeve 622, the wire thread sleeve 622 actually moves upwards, and the squeezing force of the floating ring 626 on the transmission fluid in the floating groove 625 gradually decreases. By comparing the positions of the pressure blocks 93 in several buffer tubes 91, the adjustment height of several wire thread sleeves 622 can be roughly determined, so that several wire thread sleeves 622 can be adjusted intuitively and evenly, preventing uneven adjustment of the wire thread sleeves 622 or over-adjustment of a certain wire thread sleeve 622 that would cause the main body 63 to shift or twist and deform.

[0039] The working principle of this invention is as follows:

[0040] Please see Figures 1-7 When the main body 63 is not placed on the upper end of the slide block 62, the ball 627 and the floating ring 626 are not subjected to external pressure. The ball 627 at the top of the floating ring 626 protrudes from the upper end face of the wire thread sleeve 622. At this time, the drive screw 84 has no pressure on the slide plate 83, and the buffer tube 91 is blocked by the slide plate 83. When the main body 63 is placed and the main body 63 presses against the ball 627 and the floating ring 626, the transmission fluid at the bottom end of the floating ring 626 cannot be discharged from the buffer tube 91, ensuring that the lower end face of the main body 63 and the ball 627 are in a rolling friction state. At this time, moving the main body 63 reduces the friction between the main body 63 and the upper end face of the slide block 62, making it easier to adjust the position of the main body 63, thereby solving the problem that the position of the bolt hole 631 is difficult to adjust due to the large mass of the main body 63 during installation.

[0041] After adjusting the position of the main body 63, turn the drive screw 84 to press the slide plate 83, thereby connecting the connecting hole 831 of the slide plate 83 with the buffer tube 91. At this time, the gravity of the main body 63 presses the ball 627 and the floating ring 626, making the upper end face of the ball 627 flush with the upper end face of the wire thread sleeve 622. Then, fix the main body 63 and the wire thread sleeve 622 with the fixing bolt 64. At this time, turning the hexagonal head 624 can drive the wire thread sleeve 622 to rotate, adjusting the length of the wire thread sleeve 622 extending out of the mounting groove 621, which facilitates the adjustment of the height position of the main body 63. This allows for simple and quick adjustment of the axis position of the main body 63, improving the efficiency of the axis adjustment of the main body 63.

[0042] When adjusting the length of the wire thread sleeve 622 extending out of the mounting groove 621 by turning the hexagonal head 624, the floating ring 626 is restricted from rotating. Each time the hexagonal head 624 and the wire thread sleeve 622 are turned, the wire thread sleeve 622 will squeeze the ball 627, causing the ball 627 and the floating ring 626 to move downward. This causes the floating ring 626 to squeeze the transmission fluid at the lower end, allowing the transmission fluid to enter the buffer tube 91 and push the pressure block 93 upward. When the ball 627 passes the position where the next ball 627 protrudes from the upper end face of the wire thread sleeve 622, the support spring 92 pushes the pressure block 93, causing the pressure block 93 to push the transmission fluid, pushing the floating ring 626 and the ball 627 upward. Each time the ball 627 passes the protruding position, the transmission fluid in the buffer tube 91 will float up and down once. By observing the number of times the pressure block 93 in the buffer tube 91 floats, it is easy to intuitively adjust the length of several wire thread sleeves 622 each time.

[0043] Furthermore, during the rotation of the wire thread sleeve 622, the wire thread sleeve 622 actually moves upward, and the squeezing force of the floating ring 626 in the floating groove 625 on the transmission fluid gradually decreases. By comparing the positions of the pressure blocks 93 in several buffer tubes 91, the adjustment height of several wire thread sleeves 622 can be roughly determined, so that several wire thread sleeves 622 can be adjusted intuitively and evenly, preventing uneven adjustment of the wire thread sleeves 622 or over-adjustment of a certain wire thread sleeve 622 that would cause the main body 63 to shift or twist and deform.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
