Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and in particular to a slide box. Background Technology

[0002] The function of the apron in a lathe is to convert the rotary motion transmitted from the leadscrew or feed rod into linear motion, driving the tool post feed and enabling the conversion between fast and slow speeds of the tool post movement. Both the leadscrew and feed rod are connected to the feed box. The leadscrew is used for thread cutting, causing the apron slide and the cutting tool to move at the required speed. The feed rod transmits the motion from the feed box to the apron, causing the slide and cutting tool to move at a certain speed. Since the leadscrew and feed rod are two separate power sources, if both are connected to the apron simultaneously, it will cause problems with the apron's movement. Summary of the Invention

[0003] This application provides a slide box that enables stable feeding and prevents interference between the lead screw and the guide screw.

[0004] This application provides a slide box, including: shell; The opening and closing nut mechanism includes: A nut seat is slidably disposed vertically on the outer casing; A split nut is installed on the nut seat, and the split nut is used to cooperate with the lead screw to form a transmission structure; A control component, connected to the housing, is used to control the vertical movement of the nut seat; The detachment mechanism includes: A lever is hinged to the outer casing. The lever has a first positioning groove, which has a first end A and a first end B. The shift fork is hinged to the other side of the housing relative to the shift block, and has a first driving part that is slidably inserted into the first positioning groove. A transmission component is rotatably connected to the lever block. When the first driving part is located at the first end A, the transmission component is in the transmission position. When the first driving part is located at the first end B, the transmission component is disengaged from the transmission position. An interlocking mechanism is provided between the opening and closing nut mechanism and the release mechanism, and the interlocking mechanism is used to prevent the opening and closing nut mechanism and the release mechanism from being driven at the same time; A transmission mechanism is disposed between the detachment mechanism and the machine tool, and the transmission mechanism is used to transmit power between the detachment mechanism and the machine tool.

[0005] The beneficial effects of the above embodiments are as follows: the power of the guide rod can be connected to the slide box or the transmission between the guide rod and the slide box can be disconnected by the detachment mechanism; the power of the lead screw can be connected to the slide box or the transmission between the guide rod and the slide box can be disconnected by the opening and closing nut mechanism; and the interlocking mechanism can prevent the transmission between the lead screw and the guide rod from interfering with each other, thereby enabling the slide box to move stably.

[0006] Based on the above embodiments, the embodiments of this application can be further improved as follows: In one embodiment of this application: the detachment mechanism is further provided with a limiting part connected to the housing, the shift fork has a limiting groove, and the limiting part is slidably inserted into the limiting groove. The limiting groove is used to limit the extreme angle of rotation of the shift fork. The beneficial effect of this step is that the limiting part ensures that the shift fork rotates within a preset angle range.

[0007] In one embodiment of this application: the hinge point between the lever and the housing is the first hinge point, and the hinge point between the fork and the housing is the second hinge point; when the disengagement mechanism enters the transmission position, the first driving part is located at the position furthest from the first hinge point in the first positioning groove, and the pressure of the first positioning groove on the first driving part causes the first driving part to tend to rotate away from the first hinge point; when the disengagement mechanism disengages from the transmission position, the first driving part is located at the position closest to the first hinge point in the first positioning groove, and the pressure of the first positioning groove on the first driving part causes the first driving part to tend to rotate towards the first hinge point. The beneficial effect of this step is that it enables a self-locking mechanism to be formed between the fork and the lever after the lever enters and disengages from the transmission position, thereby ensuring the stability of the lever's positioning.

[0008] In one embodiment of this application, the detachment mechanism further includes: a first handle having a ball-shaped end and a spherical portion, the spherical portion being ball-fitted into the housing, and the ball-shaped end being ball-fitted into a corresponding hole at the end of the fork; and a first elastic element inserted into the hole, applying a spring force to the ball-shaped end. The beneficial effect of this step is that the first elastic element applies a spring force to the ball-shaped end, thereby improving the stability of the first handle's positioning.

[0009] In one embodiment of this application: the control component includes: a rotating member rotatably connected to the housing, the rotating member having a second positioning groove; the nut seat having a second driving part slidably inserted into the second positioning groove; the second positioning groove having a second end A and a second end B; when the second driving part is located at the second end A, the opening / closing nut engages with the lead screw, at which time the second driving part is located at the lowest point of the second positioning groove; when the driving part is located at the second end B, the opening / closing nut separates from the lead screw. The beneficial effect of this step is that a locking structure is formed between the second driving part and the second positioning groove, thereby improving the stability of the nut seat positioning.

[0010] In one embodiment of this application: the interlocking mechanism includes: a blocking member connected to the surface of the rotating member; and a safety bar connected to the toggle block; wherein the movement trajectory of the opening / closing nut entering the transmission state is a first trajectory, and the movement trajectory of the disengagement mechanism entering the transmission state is a second trajectory. When the opening / closing nut mechanism enters the transmission state, the blocking member enters the second trajectory and blocks the rotation of the toggle block; when the disengagement mechanism enters the transmission state, the safety bar enters the first trajectory and blocks the rotation of the rotating member. The beneficial effect of this step is that the arrangement of the blocking member and the safety bar forms an interlocking structure.

[0011] In one embodiment of this application, the transmission mechanism includes: a gear sleeve rotatably connected to the housing, the gear sleeve being slidably sleeved on the guide rod; a first gear rotatably connected to the housing, the first gear meshing with the gear sleeve; a second gear rotatably connected to the housing, the second gear meshing with the first gear; a third gear rotatably connected to the lever, the third gear being coaxially arranged with the transmission component; a worm gear rotatably connected to the housing, the worm gear meshing with the transmission component; a fourth gear coaxially arranged with the worm gear; and a feed switching shaft slidably inserted into the housing, the feed switching shaft having teeth. The machine tool comprises: a rack; a feed switching gear rotatably connected to the housing, which meshes with the feed switching shaft; a fifth gear rotatably connected to the feed switching shaft, which meshes with the fourth gear and also meshes with the gear shaft in the large slide; a sixth gear coaxially arranged with the fifth gear; a seventh gear rotatably connected to the housing, which meshes with the sixth gear, and when the fifth gear meshes with the gear shaft, the sixth gear disengages from the seventh gear; and an eighth gear coaxially arranged with the seventh gear, which meshes with the rack on the machine tool.

[0012] In one embodiment of this application, the mechanism further includes: a manual feed mechanism mounted on the housing, comprising: a rotating shaft rotatably connected to the housing; a ninth gear mounted on the rotating shaft, the ninth gear meshing with the seventh gear; a handwheel slidably fitted onto the rotating shaft; a graduated ring seat mounted on the rotating shaft, the graduated ring seat having multiple spaced insertion holes centered on the axis of the rotating shaft; a positioning member connected to the handwheel, the positioning member being inserted into the insertion holes; and a second elastic member disposed between the graduated ring seat and the handwheel, the second elastic member being used to apply elastic force to the handwheel and cause the positioning member to move to the outside of the insertion holes. The beneficial effect of this step is that the manual feed mechanism enables manual driving of the longitudinal movement of the slide box.

[0013] In one embodiment of this application: the outer casing includes: a first housing connected to the bed of the machine tool, wherein the nut seat is slidably inserted vertically into a guide groove in the first housing; and a second housing connected to the front side of the first housing; wherein a notch structure is formed between the first housing and the second housing, the notch structure being used to insert a protective cover for the rack. The beneficial effect of this step is that the machine tool does not need to install a spiral steel strip or roller shutter type protective cover, but can use a low-cost, high-performance, and easy-to-clean plate-shaped protective cover.

Detailed Implementation

[0017] In this application, unless otherwise expressly specified and limited, the terminology used should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of different terms in this invention according to the specific circumstances, and the scope of the specific meaning should be limited to achieving the functions of this application.

[0018] like Figure 1-10 As shown, a slide box includes: a shell 1, an opening and closing nut mechanism 2, a release mechanism 3, a transmission mechanism 4, and an interlocking mechanism 5. The opening and closing nut mechanism 2 includes: a nut seat 201, an opening and closing nut 202, and a control component. The nut seat 201 is slidably inserted vertically into the shell 1, and the opening and closing nut 202 is installed on the nut seat 201. The opening and closing nut 202 is used to cooperate with a lead screw to form a transmission structure. The control component is connected to the shell 1 and is used to control the vertical movement of the nut seat 201. The release mechanism 3 includes: a lever 301, a lever fork 302, and a transmission component 303. The lever 301 is hinged to the shell 1 and has a first positioning groove 304. The first positioning groove 304 has a first end A305 and a first end B306. The shift fork 302 is hinged to the other side of the housing 1 relative to the shift block 301. The shift fork 302 has a first driving part 307, which is slidably inserted into the first positioning groove 304. The transmission member 303 is rotatably connected to the shift block 301. When the first driving part 307 is located at the first end A305, the transmission member 303 is located in the transmission position. When the first driving part 307 is located at the first end B306, the transmission member 303 is disengaged from the transmission position. The interlocking mechanism 5 is disposed between the opening and closing nut mechanism 2 and the disengagement mechanism 3. The interlocking mechanism 5 is used to prevent the opening and closing nut mechanism 2 and the disengagement mechanism 3 from being driven at the same time. The transmission mechanism 4 is disposed between the disengagement mechanism 3 and the machine tool. The transmission mechanism 4 is used to transmit power between the disengagement mechanism 3 and the machine tool.

[0019] In some embodiments of this application, such as Figure 3 As shown, the detachment mechanism 3 is also provided with a limiting part 308 connected to the outer shell 1. The shift fork 302 has a limiting groove 309. The limiting part 308 is slidably inserted into the limiting groove 309. The limiting groove 309 is used to limit the extreme angle of rotation of the shift fork 302, thereby ensuring that the shift fork 302 rotates within a preset angle range. Specifically, the limiting part 308 is a bolt threaded to the outer shell 1, and the end of the bolt is inserted into the limiting groove 309.

[0020] In some embodiments of this application, such as Figure 4 , 5As shown in Figures 7 and 8, the hinge point between the lever 301 and the outer shell 1 is the first hinge point 310, and the hinge point between the fork 302 and the outer shell 1 is the second hinge point 311. When the disengagement mechanism 3 enters the transmission position, the first drive unit 307 is located in the first positioning groove 304 at the position furthest from the first hinge point 310. The pressure of the first positioning groove 304 on the first drive unit 307 causes the first drive unit 307 to have a tendency to rotate away from the first hinge point 310. That is, when the transmission member 303 is subjected to pressure during transmission, it will generate an external force on the first drive unit 307 through the groove wall of the first positioning groove 304. This external force causes the fork 302 to have a tendency to rotate. However, because the first positioning groove 304 limits the first drive unit 307, the first drive unit 307 cannot move in the direction away from the first hinge point 310, and the fork 302 cannot rotate, thus forming... A self-locking structure is formed, positioning the shift fork 302 and shift block 301 in the transmission position. When the disengagement mechanism 3 disengages from the transmission position, the first drive part 307 is located in the first positioning groove 304 at the position closest to the first hinge point 310. The pressure of the first positioning groove 304 on the first drive part 307 causes the first drive part 307 to have a tendency to rotate toward the first hinge point 310. That is, when the transmission member 303 is completely disengaged from the transmission position, it will generate an external force on the first drive part 307 through the groove wall of the first positioning groove 304. This external force causes the shift fork 302 to have a tendency to rotate. However, because the first positioning groove 304 limits the first drive part 307, the first drive part 307 cannot move toward the direction close to the first hinge point 310, and the shift fork 302 cannot rotate, thus forming a self-locking structure that positions the shift fork 302 and shift block 301 in the disengaged transmission position.

[0021] In some embodiments of this application, such as Figure 4 , 7As shown, the first positioning groove 304 is a bent strip-shaped groove and includes a first bent segment A and a first bent segment B. The first end A 305 is located at the end of the first bent segment A, and the first end B 306 is located at the end of the first bent segment B. There is an included angle between the first bent segment A and the first bent segment B. The first driving part 307 is a cylindrical pin connected to the shift fork 302. When the first driving part 307 is located at the first end A 305, the external force generated by the groove wall of the first bent segment A on the first driving part 307 cannot drive the shift fork 302 to move. However, since the first driving part 307 can move towards the direction close to the first hinge point 310, the external force generated by the groove wall of the first bent segment A on the first driving part 307 cannot drive the shift fork 302 to move. Therefore, the shift fork 302 can slide in the first bent section A toward the direction closer to the first hinge point 310, thereby driving the shift block 301 to rotate downward. Similarly, when the first drive part 307 is located at the first end B306, the external force generated by the groove wall of the first bent section B on the first drive part 307 cannot drive the shift fork 302 to move. However, since the first drive part 307 can move in a direction away from the first hinge point 310, the shift fork 302 can slide in the first bent section B toward a direction away from the first hinge point 310, thereby driving the shift block 301 to rotate upward.

[0022] In some embodiments of this application, such as Figure 5 , 8 As shown, the detachment mechanism 3 also includes: a first handle 312 and a first elastic member 313. The first handle 312 has a ball end and a spherical part. The spherical part is ball-connected to the outer shell 1, and the ball end is ball-connected to the hole corresponding to the end of the shift fork 302. The first elastic member 313 is inserted into the hole and applies elastic force to the ball end. The handle facilitates the control of the rotation of the shift fork 302.

[0023] In some embodiments of this application, such as Figure 5 , 8 As shown, the first handle 312 is a spherical bearing handle. The first handle 312 rotates around the spherical part and simultaneously pries the shift fork 302 through the ball end, thereby controlling the movement of the shift fork 302. The first elastic element 313 is a cylindrical compression spring. The cylindrical compression spring is pressed into the hole at the end of the shift fork 302 through the ball end. Pressing the first handle 312 down disengages it from the transmission position, and lifting it up engages it from the transmission position. The first elastic element 313 applies elastic force to the ball end to improve the positioning stability of the first handle 312.

[0024] In some embodiments of this application, such as Figure 9-12As shown, the control component includes: a rotating member 203, which is rotatably connected to the housing 1. The rotating member 203 has a second positioning groove 204. The nut seat 201 has a second driving part 205, which is slidably inserted into the second positioning groove 204. The second positioning groove 204 has a second end A206 and a second end B207. When the second driving part 205 is located at the second end A206, the opening and closing nut 202 is engaged with the lead screw. At this time, the second driving part 205 is located at the lowest point of the second positioning groove 204. When the second driving part 205 is located at the second end B207, the opening and closing nut 202 is separated from the lead screw. At this time, the second driving part 205 is located at the lowest point of the second positioning groove 204. By cooperating with the second positioning groove 204, the opening and closing nut 202 can be positioned, thereby improving the stability of the transmission between the lead screw and the opening and closing nut 202.

[0025] In some embodiments of this application, such as Figure 9 , 11 As shown, the control assembly also includes: a second handle 208 and an opening / closing nut shaft 209. The second handle 208 is connected to one side of the opening / closing nut shaft 209, which is rotatably connected. The rotating component 203 is a bushing fitted onto one end of the opening / closing nut shaft 209. The second handle 208 drives the opening / closing nut shaft 209 to rotate, thereby causing the rotating component 203 to rotate. Raising the second handle 208 causes the opening / closing nut 202 to separate from the lead screw, and pressing the second handle 208 causes the opening / closing nut 202 to engage with the lead screw. The second drive part 205 is a columnar component connected to the rotating component 203 and extending rearward. The second positioning groove 204 is a bent strip groove and includes a second bent section A and a second bent section B. The second end A 206 is located at the end of the second bent section A, and the second end B 207 is located at the end of the second bent section B.

[0026] In some embodiments of this application, such as Figure 2 , 3 As shown, the interlocking mechanism 5 includes a blocking member 501 and a safety rod 502. The blocking member 501 is connected to the surface of the rotating member 203, and the safety rod 502 is connected to the lever 301. The blocking member 501 is a bolt connected to the rotating member 203, and the safety rod 502 is connected to the side of the lever 301 facing the rotating member 203. The movement trajectory of the opening and closing nut 202 in the transmission state is the first trajectory, and the movement trajectory of the disengagement mechanism 3 in the transmission state is the second trajectory. When the opening and closing nut mechanism 2 enters the transmission state, the blocking member 501 enters the second trajectory and blocks the rotation of the lever 301. When the disengagement mechanism 3 enters the transmission state, the safety rod 502 enters the first trajectory and blocks the rotation of the rotating member 203. The interlocking mechanism 5 limits the opening and closing nut mechanism 2 and the disengagement mechanism 3 to each other, so that the opening and closing nut mechanism 2 and the disengagement mechanism 3 cannot work at the same time, thereby ensuring the stability of the slide box movement.

[0027] In some embodiments of this application, such as Figure 3 , 14 As shown in Figure 15, the transmission mechanism 4 includes: a gear sleeve 401, a first gear 402, a second gear 403, a third gear 404, a worm gear 405, a fourth gear 406, a feed switching shaft 407, a feed switching gear 408, a fifth gear 409, a sixth gear 410, a seventh gear 411, and an eighth gear 412. The gear sleeve 401 is rotatably connected to the outer shell 1 and slidably sleeved on the guide rod. The first gear 402 is rotatably connected to the outer shell 1 and meshes with the gear sleeve 401. The second gear 403 is rotatably connected to the outer shell 1 and meshes with the first gear 402. The third gear 404 is rotatably connected to the lever 301 and is coaxially arranged with the transmission component 303. The transmission component 303 is a worm gear. The worm gear 405 is rotatably connected to the outer shell 1 and is used to interact with the transmission component 303. 3. Engagement: The fourth gear 406 and the worm gear 405 are coaxially arranged. The feed switching shaft 407 is slidably inserted into the housing 1. The feed switching shaft 407 has a rack portion. The feed switching gear 408 is rotatably connected to the housing 1 and meshes with the feed switching shaft 407. The fifth gear 409 is rotatably connected to the feed switching shaft 407 and meshes with the fourth gear 406. The fifth gear 409 is also used to mesh with the gear shaft in the large slide. The sixth gear 410 is coaxially arranged with the fifth gear 409. The seventh gear 411 is rotatably connected to the housing 1 and meshes with the sixth gear 410. When the fifth gear 409 meshes with the gear shaft, the sixth gear 410 and the seventh gear 411 separate. The eighth gear 412 is coaxially arranged with the seventh gear 411 and meshes with the rack on the machine tool.

[0028] In some embodiments of this application, such as Figure 4 As shown, the transmission mechanism 4 also includes: a third handle 413, a limiting member 414, and a third elastic member 415. One end of the third handle 413 is connected to the feed switching gear 408. The feed switching gear 408 is rotated by rotating the third handle 413. The limiting member 414 is a ball and is slidably disposed in the hole opened in the outer shell 1. The third elastic member 415 is a cylindrical compression spring. The third elastic member 415 is disposed in the hole and applies elastic force to the limiting member 414. The feed switching shaft 407 has a first annular groove 416 and a second annular groove 417 that are spaced apart from each other. When the elastic member enters the first annular groove 416, the tool is fed longitudinally. When the elastic member enters the second annular groove 417, the tool is fed laterally.

[0029] In some embodiments of this application, such as Figure 16As shown, the slide box also includes: a manual feed mechanism 6, which is mounted on the housing 1. The manual feed mechanism 6 includes: a rotating shaft 601, a ninth gear 602, a handwheel 603, a scale ring seat 604, a positioning element 605, and a second elastic element 606. The rotating shaft 601 is rotatably connected to the housing 1. The ninth gear 602 is mounted on the rotating shaft 601 and meshes with the seventh gear 411. The handwheel 603 is slidably fitted onto the rotating shaft 601. 604 is installed on the rotating shaft 601. The scale ring seat 604 has a plurality of evenly spaced insertion holes 607 with the axis of the rotating shaft 601 as the center line. The positioning member 605 is connected to the handwheel 603 and is used to be inserted into the insertion hole 607. The second elastic member 606 is disposed between the scale ring seat 604 and the handwheel 603. The second elastic member 606 is used to apply elastic force to the handwheel 603 and make the positioning member 605 move to the outside of the insertion hole 607.

[0030] In some embodiments of this application, such as Figure 16 As shown, the second elastic element 606 is a cylindrical compression spring, the positioning element 605 is a cylindrical structure, and the number of insertion holes 607 is an integer multiple of the number of positioning elements 605. The positioning elements 605 can enter the insertion holes 607 simultaneously. The manual feed mechanism 6 also includes a baffle, which is installed at the outermost end of the rotating shaft 601. The baffle is used to limit the handwheel 603 and prevent the handwheel 603 from falling off. By pushing the handwheel 603, the positioning element 605 enters the insertion hole 607. By rotating the handwheel 603, the ninth gear 602 drives the eighth gear 412 to rotate, thereby manually driving the slide box to move longitudinally.

[0031] In some embodiments of this application, such as Figure 13 As shown, the outer casing 1 includes a first casing and a second casing. The first casing is connected to the bed of the machine tool. A nut seat 201 is slidably inserted into the first casing along the vertical direction. The second casing is connected to the front side of the first casing. A notch structure 101 is formed between the first casing and the second casing. The notch structure 101 is used to insert a protective cover for the rack. The outer casing 1 is designed as two parts to prevent the plate-shaped cover from interfering with the slide box. This allows the machine tool to use a low-cost, high-performance, and easy-to-clean plate-shaped cover instead of a spiral steel belt or roller shutter type protective cover.

[0032] In some embodiments of this application, such as Figure 13 As shown, the outer casing 1 also includes a scraper 102, which is connected to the second casing. The lower end of the scraper 102 extends into the notch structure 101. The scraper 102 is used to scrape off the material from the surface of the shield.

[0033] This type of slide box can achieve longitudinal and transverse feeding functions through the drop mechanism 3 and the guide rod. It can also be used with the lead screw for longitudinal feeding, or manually fed longitudinally through the manual feeding mechanism 6.

[0034] (1) Longitudinal feed in conjunction with the optical bar Raising the first handle 312 causes the worm to engage with the worm wheel 405, which in turn drives the gear sleeve 401 to rotate. The gear sleeve 401 drives the worm to rotate through the first gear 402, the second gear 403, and the third gear 404. The worm drives the worm wheel 405 to rotate, and the worm wheel 405 drives the eighth gear 412 to rotate through the fourth gear 406, the fifth gear 409, the sixth gear 410, and the seventh gear 411. The eighth gear 412 meshes with the rack on the machine tool bed, thereby realizing the longitudinal feed motion. (2) Lateral feed in conjunction with the optical bar Rotating the third handle 413 causes the feed switching gear 408 to rotate, which in turn drives the feed switching shaft 407 to slide in the housing, causing the sixth gear 410 to separate from the seventh gear 411. At the same time, the fifth gear 409 meshes with the gear shaft in the large slide plate, thereby transmitting the power of the optical rod laterally and thus realizing the lateral feed motion. (3) Longitudinal transmission in conjunction with the lead screw. Pressing down the first handle 312 separates the worm from the worm wheel 405. Pressing down the second handle 208 causes the nut seat 201 to slide upward, opening and closing the nut 202 to mesh with the lead screw, thereby realizing the longitudinal feed transmission of the lead screw. (4) Manual feed transmission Lifting the second handle 208 causes the nut seat 201 to slide downwards, separating the opening and closing nut 202 from the lead screw. Pushing the handwheel 603 allows the positioning part 605 to enter the insertion hole 607. Rotating the handwheel 603 causes the ninth gear 602 to drive the eighth gear 412 to rotate through the seventh gear 411, thereby realizing the manual feed function.
