Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and in particular to a rack-based milling machine worktable lateral movement mechanism. Background Art

[0002] The milling machine table combines the rotary motion of the milling cutter and the feed motion of the workpiece to process various surfaces of the workpiece, and the milling cutter is driven by the transverse movement mechanism to move horizontally or vertically. The transverse movement mechanism mainly includes a motor and a rack. The motor is controlled by the controller, and the motor drives the rack to rotate, thereby driving the milling cutter to move as a whole. Technical inspiration for the transverse movement mechanism; The following problems were found in the study of the transverse mechanism: The transverse mechanism uses a milling cutter to perform moving processing on the workpiece. The milling cutter is prone to generate a large amount of debris during the processing. The debris splashes to the upper end of the transverse mechanism, causing the debris to accumulate on the upper end of the transverse mechanism, which needs to be manually cleaned later. As a result, the transverse mechanism cannot use the friction generated by the rotation of the rack to clean the debris on the upper end of the transverse mechanism; At present, CN201610103287.X in the prior art is a CNC bridge-type elevated crossbeam moving gantry high-speed engraving and milling machine, which discloses a milling machine. The two ends of the crossbeam of the invention are respectively arranged on the left wall and the right wall, and form a horizontal moving pair with the left wall and the right wall respectively; the front slide and the rear slide are arranged in parallel, the front part of the front slide and the crossbeam form a horizontal moving pair, and the rear part of the rear slide and the crossbeam form a horizontal moving pair; the ram is located between the front slide and the rear slide, the front part of the ram and the front slide form a vertical moving pair, and the rear part of the ram and the rear slide form a vertical moving pair; the spindle is arranged at the lower part of the ram for installing the engraving milling cutter. Since the crossbeam in the present invention is supported by the left wall and the right wall, the accuracy of forward milling and reverse milling of the workpiece is the same; The present invention can mainly solve the problem that the transverse movement mechanism cannot utilize the friction generated when the rack rotates to clean the debris on the upper end of the transverse movement mechanism. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a rack-based milling machine table transverse movement mechanism to solve the problems described in the above background technology.

[0004] The purpose and function of the rack-based transverse movement mechanism of a milling machine table of the present invention are achieved by the following specific technical means: a rack-based transverse movement mechanism of a milling machine table, comprising a transverse movement table, motors are provided on both sides of the upper end of the transverse movement table, the inner side of the motor is rotatably connected to a rack, and one side of the rack is slidably connected to a mounting frame.

[0005] Furthermore, the traverse table is installed on the upper end of the milling machine workbench, and the motor is connected to the power supply return through a power cord.

[0006] Furthermore, the rack is laterally passed through the upper end of the transverse moving platform, and the motors at both ends of the rack drive the rack to rotate forward and reverse respectively, and a ring is surrounded on the outer side of the rack.

[0007] Furthermore, the mounting frame is slidably connected to the outer side of the rack. When the rack rotates, the mounting frame slides horizontally on one side of the rack, and a milling cutter is installed at one end of the mounting frame.

[0008] Furthermore, the rings are arranged in plurality on the outside of the rack. When the rack rotates, the rings swing synchronously. When the mounting frame moves, the mounting frame is squeezed to one side of the rings. At this time, the distance between the rings is shortened, and the rings at both ends of the rack are installed on the inner side of the mounting frame.

[0009] Furthermore, a scraper is provided at the lower end of the collar, and rotating shafts are hinged on both sides of the lower end of the scraper, and the lower end of the rotating shaft is swingably connected to a bottom scraper.

[0010] Furthermore, the scraper is matched with the collar, and the rotating shaft swings at 45-90 degrees at the lower end of the scraper.

[0011] Furthermore, the bottom scraper swings on both sides of the lower end of the scraper, the bottom scrapers are arranged in a horizontal staggered manner, the bottom scraper and the rotating shaft are matched, and the lower end of the bottom scraper is horizontally swung and fitted with the lower end of the transverse platform.

[0012] Furthermore, a rotating sphere is hinged between the rings, one end of the rotating sphere is swingably connected to a support arm, the end of the support arm away from the rotating sphere is hinged to a universal ball, a cross bar is installed between the universal balls, and a tightening rod is provided at the lower end of the cross bar.

[0013] Furthermore, the support arms are vertically inclined at 15-60 degrees, and two support arms form a group. The two ends of the support arms are respectively hinged with a rotating sphere and a universal ball, and each group of support arms is triangular.

[0014] Furthermore, the crossbar is arranged horizontally, the universal balls are distributed at both ends of the crossbar, the clamping rod is inclined at 25-45 degrees, and the clamping rod is horizontally fitted with the side of the bottom scraper.

[0015] Furthermore, a convex block is penetrated through one side of the upper end of the transverse moving platform close to the mounting frame, a telescopic rod is slidably connected to the lower end of the convex block, and a gasket is provided at the lower end of the telescopic rod.

[0016] Furthermore, a groove is provided on one side of the mounting frame close to the protrusion, and the height of the groove is greater than half of the height of the protrusion. When the mounting frame slides, the groove on one side of the mounting frame slides on the outer side of the protrusion.

[0017] Furthermore, the telescopic rods are arranged horizontally in multiple groups, and each group of telescopic rods is vertically slidably nested. The gaskets are matched with the telescopic rods, and the gaskets are arranged in an arc shape. The arched ends of the gaskets slide and fit with the inner wall of the groove of the mounting frame.

[0018] Beneficial effects: 1. When the rack rotates, the sleeve ring and the scraper swing synchronously. At this time, the scraper drives the bottom scraper to swing forward and backward. Since the bottom scraper swings left and right through the rotating shaft, the bottom scraper cannot swing through the rotating shaft at this time, so that the bottom scraper can scrape the upper end of the transverse table. When the rack rotates, the transverse mechanism can use the rotation of the rack to clean the upper end of the transverse mechanism. The debris is prevented from splashing to the upper end of the transverse mechanism when the milling cutter processes the workpiece; 2. Since the mounting frame drives the milling cutter to slide horizontally, when the mounting frame slides, the collar on one side of the mounting frame is squeezed, and the distance between the collars is shortened. At this time, the support arm inside the collar swings downward through the rotating sphere, and the distance between the collars on the other side of the mounting frame increases. The support arm on the other side swings upward as a whole, and the support arm on the other side drives the clamping rod to move upward through the cross bar. The clamping rod is squeezed to one side of the bottom scraper. The bottom scraper can form a swinging cleaning on the upper end of the transverse platform during the sliding process of the collar; 3. At this time, when the support arm on one side of the mounting frame tilts downward and swings, the support arm drives the cross bar downward synchronously through the universal ball, and the clamping rod at the lower end of the cross bar moves downward synchronously, the clamping rod is tilted 25-45 degrees, and the clamping rod is horizontally fitted with the side of the bottom scraper. When the clamping rod slides downward, the clamping rod can be squeezed to one side of the bottom scraper, and the bottom scraper can be tilted and swung through the rotating shaft. At this time, the bottom scraper at the lower end of the scraper can be in a horizontal overlapping state, which is convenient for the rings to form a fit, and then it is convenient for the mounting frame to slide on the outer side of the rack; 4. When the mounting frame slides, since the gasket is arranged in an arc shape, the gasket can slide and fit to the inner side of the groove of the mounting frame. When the mounting frame stops sliding, each group of telescopic rods is vertically slid and nested. At this time, the gasket slides downward through the telescopic rod. The gasket can form a tight contact with the inner side of the groove of the mounting frame through the telescopic rod. The tight contact of the gasket can increase the stability of the mounting frame after it stops sliding, thereby avoiding the situation where the stability of the mounting frame is poor due to the mobility of the mounting frame.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0030] As attached Figure 1 To Attachment Fig. 9 As shown: Embodiment 1: A rack-based milling machine table transverse movement mechanism comprises a transverse movement platform 1, wherein motors 101 are provided on both sides of the upper end of the transverse movement platform 1, a rack 102 is rotatably connected to the inner side of the motor 101, and a mounting frame 103 is slidably connected to one side of the rack 102; Wherein: the traverse table 1 is installed at the upper end of the milling machine workbench, and the motor 101 is connected to the power supply return through the power line; A motor 101 and a rack 102, wherein the rack 102 is horizontally passed through the upper end of the traverse platform 1, and the motors 101 at both ends of the rack 102 drive the rack 102 to rotate forward and reverse respectively, and a collar 2 surrounds the outer side of the rack 102; A mounting frame 103, the mounting frame 103 is slidably connected to the outer side of the rack 102, when the rack 102 rotates, the mounting frame 103 slides horizontally on one side of the rack 102, and a milling cutter is installed at one end of the mounting frame 103; The mounting frame 103 is connected to the outer side of the rack 102 close to the collar 2 of the mounting frame 103. When the mounting frame 103 moves, the mounting frame 103 can be squeezed to one side of the collar 2; The rings 2 are arranged in plurality on the outer side of the rack 102. When the rack 102 rotates, the rings 2 swing synchronously. When the mounting frame 103 moves, the mounting frame 103 is pressed to one side of the rings 2. At this time, the distance between the rings 2 is shortened, and the rings 2 at both ends of the rack 102 are mounted on the inner side of the mounting frame 103. The collars 2 at both ends of the rack 102 are mounted on the inner side of the mounting frame 103 to prevent the collars 2 from sliding due to the sliding of the mounting frame 103, causing the collars 2 to move as a whole; When the rack 102 rotates, since the ring 2 is sleeved on the outer side of the rack 102, the rack 102 rubs against the inner wall of the ring 2, and the ring 2 swings synchronously at this time, and the ring 2 swings vertically as a whole; Wherein: the traverse table 1 is installed on the upper end of the milling machine worktable, and the motors 101 at both ends of the rack 102 respectively drive the rack 102 to rotate forward and reversely. Through the forward and reverse rotation of the rack 102, the mounting frame 103 slides horizontally on one side of the rack 102. Since a milling cutter is installed at one end of the mounting frame 103, the milling cutter can move and process the workpiece on the milling machine worktable. At the same time, since the collar 2 is sleeved on the outer side of the rack 102, the rack 102 rubs against the inner wall of the collar 2. At this time, the collar 2 swings synchronously, and the collar 2 swings vertically as a whole; Example 2: Refer to the attached manual Figure 2-7 It can be seen that the difference between Example 2 and Example 1 is that a scraper 201 is provided at the lower end of the collar 2, and a rotating shaft 202 is hinged on both sides of the lower end of the scraper 201, and the lower end of the rotating shaft 202 is swingably connected to a bottom scraper 203; Wherein: the scraper 201, the scraper 201 is matched with the collar 2, and the rotating shaft 202 swings at 45-90 degrees at the lower end of the scraper 201; The bottom scraper 203 swings on both sides of the lower end of the scraper 201, and the bottom scrapers 203 are arranged in a horizontal staggered manner. The bottom scraper 203 and the rotating shaft 202 are matched, and the lower end of the bottom scraper 203 is horizontally swung and fitted with the lower end of the transverse platform 1; The bottom scrapers 203 are arranged horizontally in a staggered manner. Therefore, when the bottom scrapers 203 are tilted and swung by the rotating shaft 202, the bottom scrapers 203 can overlap each other. Figure 6 As shown; Wherein: when the rack 102 rotates, the collar 2 and the scraper 201 swing synchronously, and the scraper 201 drives the bottom scraper 203 to swing forward and backward. Since the bottom scraper 203 swings left and right through the rotating shaft 202, the bottom scraper 203 cannot swing through the rotating shaft 202 at this time, so that the bottom scraper 203 can scrape the upper end of the traverse table 1. When the rack 102 rotates, the traverse mechanism can use the rotation of the rack 102 to clean the upper end of the traverse mechanism. The debris is prevented from splashing to the upper end of the traverse mechanism when the milling cutter processes the workpiece; Example 3: Refer to the attached manual Figure 5-7 It can be seen that the difference between Example 3 and Examples 1-2 is that a rotating sphere 3 is hinged between the rings 2, one end of the rotating sphere 3 is swingably connected to a support arm 301, and the end of the support arm 301 away from the rotating sphere 3 is hinged to a universal ball 302, a cross bar 303 is set between the universal balls 302, and a tightening rod 304 is provided at the lower end of the cross bar 303; Wherein: the rotating sphere 3 and the support arm 301, the support arm 301 is vertically inclined at 15-60 degrees, and each pair of the support arms 301 is in a group, and the two ends of the support arms 301 are respectively hinged with the rotating sphere 3 and the universal ball 302, and each group of the support arms 301 is triangular; Each pair of arms 301 is in a group, and the two ends of the arms 301 are respectively hinged with a rotating sphere 3 and a universal ball 302. Each group of arms 301 is in a triangular shape. Figure 5 As shown; The cross bar 303 and the abutting bar 304, the cross bar 303 is arranged horizontally, the universal balls 302 are distributed at both ends of the cross bar 303, the abutting bar 304 is inclined at 25-45 degrees, and the abutting bar 304 is horizontally fitted with the side of the bottom scraper 203; The pressing rod 304 is inclined at 25-45 degrees, and the pressing rod 304 is horizontally fitted with the side of the bottom scraper 203. When the pressing rod 304 slides downward, the pressing rod 304 can be pressed to one side of the bottom scraper 203, and the bottom scraper 203 can be tilted and swung through the rotating shaft 202; Among them: since the mounting frame 103 drives the milling cutter to slide horizontally, when the mounting frame 103 slides, the collar 2 on one side of the mounting frame 103 is squeezed, and the distance between the collars 2 is shortened. At this time, the support arm 301 on the inner side of the collar 2 is tilted downward by rotating the sphere 3, and the distance between the collars 2 on the other side of the mounting frame 103 increases, and the support arm 301 on the other side is tilted upward as a whole. The support arm 301 on the other side drives the clamping rod 304 to move upward through the cross bar 303, and the clamping rod 304 is squeezed to one side of the bottom scraper 203. The bottom scraper 203 can form a swinging cleaning on the upper end of the traverse platform 1 during the sliding process of the collar 2; At this time, when the support arm 301 on one side of the mounting frame 103 tilts downward and swings, the support arm 301 drives the cross bar 303 to move downward synchronously through the universal ball 302, and the clamping rod 304 at the lower end of the cross bar 303 moves downward synchronously, and the clamping rod 304 is inclined at 25-45 degrees, and the clamping rod 304 is horizontally fitted with the side of the bottom scraper 203. When the clamping rod 304 slides downward, the clamping rod 304 can be squeezed to one side of the bottom scraper 203, and the bottom scraper 203 can be tilted and swung through the rotating shaft 202. At this time, the bottom scraper 203 at the lower end of the scraper 201 can be in a horizontally overlapping state, which is convenient for the collar 2 to form a fit, and then it is convenient for the mounting frame 103 to slide on the outer side of the rack 102; Example 4: Refer to the attached manual Figure 2 , 8 As can be seen from Figures 9 and 10, the difference between Example 4 and Examples 1-3 is that a protrusion 4 is penetrated on one side of the upper end of the traverse platform 1 close to the mounting frame 103, and a telescopic rod 401 is slidably connected to the lower end of the protrusion 4, and a gasket 402 is provided at the lower end of the telescopic rod 401; Among them: the protrusion 4, the mounting frame 103 has a groove on one side close to the protrusion 4, the height of the groove is greater than half of the height of the protrusion 4, when the mounting frame 103 slides, the groove on one side of the mounting frame 103 slides on the outer side of the protrusion 4; Telescopic rods 401 are arranged in multiple groups horizontally, and each group of telescopic rods 401 is vertically slidably nested. Gaskets 402 are matched with the telescopic rods 401, and the gaskets 402 are arranged in an arc shape. The arched end of the gasket 402 is slidably fitted with the inner wall of the groove of the mounting frame 103; The telescopic rods 401 are arranged in multiple groups horizontally, and each group of the telescopic rods 401 is vertically slidably nested, and the vertical sliding height of the telescopic rods 401 is 1-2 cm; The gasket 402 is arranged in an arc shape, so that when the mounting frame 103 slides horizontally, the gasket 402 can slide and fit into the inner side of the groove of the mounting frame 103; Among them: when the mounting frame 103 slides, since the gasket 402 is arranged in an arc shape, the gasket 402 can slide and fit to the inner side of the groove of the mounting frame 103, and the mounting frame 103 stops sliding, and each group of telescopic rods 401 are vertically slid and nested. At this time, the gasket 402 slides downward through the telescopic rod 401, and the gasket 402 can form a tight contact with the inner side of the groove of the mounting frame 103 through the telescopic rod 401. The tight contact of the gasket 402 can increase the stability of the mounting frame 103 after it stops sliding, thereby avoiding the situation where the stability of the mounting frame 103 is poor due to the mobility of the mounting frame 103.
