Description

Technical Field

[0001] This invention relates to the technical field of vertical machining centers, and more particularly to an integrated loading and cutting device for vertical machining center components. Background Technology

[0002] The core motion axes (X / Y / Z axes) of a vertical machining center rely on lead screws to convert the rotary motion of the servo motor into precise linear motion of the worktable or spindle. Therefore, the lead screw is an indispensable transmission component in a vertical machining center. The lead screw needs to be reliably connected to the output shaft of the servo motor or a reduction mechanism through a shaft end connection structure. Therefore, during the manufacturing process of the lead screw, a connection structure needs to be machined into the shaft end. Typically, this structure is achieved through turning. For example, the most common threaded end connection in vertical machining center lead screws requires machining external threads into the shaft end of the lead screw for installing lock nuts or couplings.

[0003] Because vertical machining centers are generally large, the length of the lead screw also increases. In existing lathes, the length that a standard three-jaw chuck can hold is limited, making it difficult to machine longer lead screws. Excessive holding length can cause the lead screw axis to deviate from the center of rotation during machining, resulting in wobbling. Furthermore, longer lead screws are difficult to load stably manually.

[0004] Therefore, it is necessary to provide an integrated loading and cutting device that can stably turn long lead screws and facilitates rapid loading and unloading of lead screws. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated loading and cutting device for vertical machining center components to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vertical machining center component loading and cutting integrated device, comprising a loading rack and a cutting mechanism.

[0007] The cutting mechanism is configured as an open type and is connected to the loading rack;

[0008] The cutting mechanism includes a clamping mechanism through which the lead screw body can pass and a feeding mechanism that drives the lead screw body to feed axially. The feeding rack screens and feeds the lead screw body to the feeding mechanism. The feeding mechanism drives the shaft end of the lead screw body through the clamping mechanism to the cutting station. The clamping mechanism clamps the lead screw body and rotates it for cutting.

[0009] In one embodiment, the cutting mechanism further includes at least one set of support parts, which receive the lead screw body of the screening feed and align it with the clamping mechanism.

[0010] In one embodiment, the feeding rack is tilted at an angle, and the feeding rack includes an L-shaped feeding plate. Several lead screw bodies to be processed are arranged sequentially inside the L-shaped feeding plate, and a pair of liftable top blocks are provided on one side of the end of the L-shaped feeding plate.

[0011] In one embodiment, a dropping frame is provided at one end of the L-shaped feeding plate, and the feeding mechanism is located at the starting end of the dropping frame.

[0012] In one embodiment, a pair of transition plates are provided at the starting end of the unloading rack, and the transition plates are connected to the end of the L-shaped loading plate.

[0013] In one embodiment, the support includes a pair of support seats, the upper end of the support seats is provided with a support roller and a pair of support wheels, and a brake plate is provided on one side of the support roller.

[0014] In one embodiment, a liftable inclined block is provided between a pair of support wheels, which lifts the lead screw body.

[0015] In one embodiment, the feeding mechanism includes a pair of grippers, the lower ends of which are hinged, and a linear drive mechanism is provided on the lower side of the grippers.

[0016] In one embodiment, the clamping mechanism includes a three-jaw chuck with a feed port extending through its center.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention features an open cutting mechanism, which facilitates cooperation with the loading rack and can accommodate longer lead screw bodies for cutting. A batch of lead screw bodies to be processed are placed on the loading rack. Individual lead screw bodies are screened out by the loading rack and fed onto the feeding mechanism. The feeding mechanism drives the current lead screw body to perform axial displacement, so that the lead screw body passes through the clamping mechanism. The shaft end to be processed passes through the clamping mechanism and extends to the cutting station on the other side. A corresponding cutting tool assembly is provided at the cutting station. The lead screw body is clamped and rotated by a clamping mechanism, and the turning tool assembly is used to perform turning on the shaft end. Then, the lead screw body is driven to return to its axial position by a feed mechanism. Similarly, the lead screw body is unloaded by a loading rack. At the same time, subsequent lead screw bodies are screened and loaded, thus realizing integrated production of loading and cutting of long lead screw bodies. The through-type clamping mechanism and the open cutting mechanism enable stable cutting of long lead screw bodies. In addition, the loading rack further facilitates convenient loading of long lead screw bodies. Attached Figure Description

[0036] Please see Figure 1-8 The present invention provides a technical solution: a vertical machining center component loading and cutting integrated device, comprising a loading rack 1 and a cutting mechanism 2.

[0037] The cutting mechanism 2 is configured as an open type and is connected to the feeding rack 1;

[0038] The cutting mechanism 2 includes a clamping mechanism through which the lead screw body 6 can pass and a feeding mechanism 3 that drives the lead screw body 6 to feed axially. The feeding rack 1 screens and feeds the lead screw body 6 to the feeding mechanism 3. The feeding mechanism 3 drives the shaft end of the lead screw body 6 to pass through the clamping mechanism to the cutting station. The clamping mechanism clamps the lead screw body 6 and rotates it to perform cutting.

[0039] Preferably, the cutting mechanism 2 is designed to be open, which facilitates its cooperation with the loading rack 1 and allows for the cutting of longer lead screw bodies 6. Specifically, a batch of lead screw bodies 6 to be processed are placed on the loading rack 1. The loading rack 1 screens out individual lead screw bodies 6 and feeds them onto the feeding mechanism 3. The feeding mechanism 3 drives the current lead screw body 6 to perform axial displacement, so that the lead screw body 6 passes through the clamping mechanism. The shaft end to be processed passes through the clamping mechanism and extends to the cutting station on the other side. A corresponding turning tool assembly is provided at the cutting station (the turning tool assembly is prior art and is not shown in the figure). The screw body 6 is clamped and rotated by the clamping mechanism, and the turning tool assembly is used to perform turning on the shaft end. Then, the screw body 6 is driven to return to its axial position by the feed mechanism 3. The screw body 6 is unloaded by the loading rack 1. At the same time, subsequent screw bodies 6 are screened and loaded, thus realizing the integrated production of loading and cutting of long screw bodies 6. The through-type clamping mechanism and the open cutting mechanism 2 enable stable cutting of long screw bodies 6. In addition, the loading rack 1 further facilitates the convenient loading of long screw bodies 6.

[0040] The cutting mechanism 2 also includes at least one set of support parts 201, which receive the lead screw body 6 of the screening feed and align it with the clamping mechanism.

[0041] Preferably, the lead screw body 6 of the feeding rack 1 first falls onto the support part 201 for limiting support. In this embodiment, two sets of support parts 201 are provided to support both sides of the long lead screw body 6 respectively, and align its axis with the axis of the clamping mechanism to facilitate subsequent passage through the clamping mechanism.

[0042] The feeding rack 1 is tilted at an angle. The feeding rack 1 includes an L-shaped feeding plate 101. Several lead screw bodies 6 to be processed are arranged in sequence inside the L-shaped feeding plate 101. A pair of liftable top blocks 102 are provided on one side of the end of the L-shaped feeding plate 101.

[0043] Preferably, based on the rolling characteristics of the lead screw body 6 and the effect of gravity, the feeding frame 1 is set to be inclined. Several lead screw bodies 6 to be processed are arranged in sequence and restricted in the L-shaped feeding plate 101. When feeding is required, a pair of top blocks 102 move upward to lift the lead screw body 6 at the end. Under the action of gravity, the lead screw body 6 rolls downward, which can then be separated from the L-shaped feeding plate 101 and fall onto the feeding mechanism 3, thus completing the screening and feeding function.

[0044] Preferably, the top block 102 can be driven by a cylinder assembly;

[0045] Preferably, when the lead screw body 6 falls onto the feed mechanism 3, its two ends are supported by two sets of support parts 201, which restricts the position of the lead screw body 6 and facilitates axial feeding in conjunction with the feed mechanism 3.

[0046] One end of the L-shaped feeding plate 101 is provided with a dropping frame 103, and the feeding mechanism 3 is located at the starting end of the dropping frame 103.

[0047] Preferably, a dropping rack 103 is connected to the end of the L-shaped feeding plate 101. After the lead screw body 6 has finished processing, the lead screw body 6 rolls onto the dropping rack 103 to collect the processed lead screw body 6.

[0048] The starting end of the unloading rack 103 is provided with a pair of transition plates 104, which are connected to the end of the L-shaped loading plate 101.

[0049] Preferably, a transition plate 104 is provided to connect the L-shaped feeding plate 101 and the support part 201, so that the lead screw body 6 can roll along the transition plate 104 to the support part 201 under the lifting action of the top material block 102.

[0050] The support part 201 includes a pair of support seats 202. The upper end of the support seat 202 is provided with a support roller 203 and a pair of support wheels 204. A brake plate 205 is provided on one side of the support roller 203.

[0051] Preferably, the support part 201 is configured as a support roller 203 and a support wheel 204. Under the transition action of the transition plate 104, the lead screw body 6 rolls between the two. While ensuring that the axis of the lead screw body 6 is aligned, it can also perform adaptive rolling, so that the lead screw body 6 can still be stably supported when it rotates.

[0052] Preferably, a brake plate 205 is provided on one side of the support roller 203. The brake plate 205 further prevents the lead screw body 6 from disengaging from the support roller 203 and the support wheel 204 due to the rolling inertia of the transition plate 104.

[0053] A liftable inclined block 206 is provided between a pair of support wheels 204, which lifts the lead screw body 6.

[0054] Preferably, after the lead screw body 6 is processed, a sloping block 206 is similarly provided. The sloping block 206 is located between a pair of support wheels 204, and its upper sloping surface is adapted to the sloping surface of the brake plate 205. When the sloping block 206 is lifted upward, it lifts the lead screw body 6 upward, and the lead screw body 6 rolls along the sloping surface until it contacts the brake plate 205, until it passes the brake plate 205 and rolls onto the unloading rack 103. At the same time, the top block 102 also lifts the next lead screw body 6 for loading, so that loading and unloading are carried out simultaneously, improving the convenience of processing.

[0055] Preferably, an electric telescopic cylinder is provided inside the support base 202 to drive the inclined top block 206.

[0056] The feeding mechanism 3 includes a pair of grippers 301, the lower ends of the pair of grippers 301 are hinged, and a linear drive mechanism is provided on the lower side of the grippers 301.

[0057] Preferably, a pair of grippers 301 are provided to open and close hingedly to clamp the lead screw body 6 and drive it to move axially through a linear drive mechanism. When loading and unloading the lead screw body 6, the pair of grippers 301 are fully extended, so that the position height of the grippers 301 is lower than the height of the brake plate 205, so as not to affect the rolling loading and unloading of the lead screw body 6.

[0058] Preferably, the linear drive mechanism includes, but is not limited to, a lead screw mechanism, a gear and rack mechanism, or a cylinder and other drive components;

[0059] Preferably, when it is necessary to control the opening and closing of the gripper 301, a pair of limiting plates 302 are provided. The pair of limiting plates 302 are located on both sides of the gripper 301 and are in a vertical state. When the pair of limiting plates 302 rises or falls relative to the gripper 301, the pair of grippers 301 can be driven to open and close. Specifically, the height of the gripper 301 itself remains unchanged, and its outer side is set as a plane. When the limiting plates 302 rise relative to the gripper 301, the gripper 301 is pushed upward along its plane until the pair of grippers 301 clamps the lead screw body 6. Conversely, when the limiting plates 302 fall, the grippers 301 unfold under the action of gravity. The structural design is simple and does not require multiple gears to mesh to achieve hinge connection opening and closing control, which is highly practical.

[0060] Preferably, a rotating rod is provided at the upper end of the limiting plate 302, thereby further reducing the frictional force of the limiting plate 302 pushing the gripper 301 to open and close, and improving the service life;

[0061] Preferably, the linear drive mechanism includes a threaded rod 303, through which a nut seat 304 is threadedly connected. Concave frames 305 are provided at both ends of the gripper 301, which are located on the upper side of the nut seat 304. A pair of guide side plates 306 are provided between a pair of support seats 202 to guide the displacement of the nut seat 304. By driving the threaded rod 303 to rotate through the motor 7, the gripper 301 can be driven to perform linear reciprocating displacement, thereby realizing the axial feed of the screw body 6.

[0062] Preferably, a concave plate 307 is fixedly connected to the lower end of a pair of limiting plates 302. The inner side of the limiting plate 302 slides vertically with the concave frame 305. The lower side of the guide side plate 306 is hollowed out to facilitate the vertical displacement of the concave plate 307. Optionally, due to the limited installation space, the driving component can only be set on the lower side of the concave plate 307. A cylinder assembly can be set on the lower side of the concave plate 307 to drive the concave plate 307 to lift and lower.

[0063] Optionally, since the above embodiment requires the driving cylinder assembly to be set on the lower side of the concave plate 307 for driving, the concave plate 307 itself needs to follow the gripper 301 to reciprocate, making the cylinder assembly itself in an unstable state. Moreover, the cylinder needs to be connected to the air pipe, which bends, extends, or is dragged as it moves, greatly affecting its service life. Therefore, hook grooves 8 are provided on both sides of the nut seat 304, and a limiting post is provided in the hook groove 8. The limiting post is connected to the inner side of the concave plate 307, and the lower end of the concave frame 305 slides with the upper end of the nut seat 304. When the nut seat 304 is horizontally displaced relative to the concave frame 305 and the concave plate 307, the inclined groove of the hook groove 8 restricts the limiting post to move, so that the limiting post can move upward or downward along the inclined groove, thereby realizing that the limiting plate 302 drives the gripper 301 to clamp or release the gripper 301 downward.

[0064] A path groove is formed through the guide side plate 306. A second limiting post 308 is located within the path groove. The second limiting post 308 is connected to the outer side of the concave plate 307. In the initial position, the inclined groove of the hook-shaped groove 8 is aligned with the inclined groove of the path groove. At this time, the first limiting post is at the bottom of the hook-shaped groove 8, and the second limiting post 308 is at the bottom of the inclined groove of the path groove. This positions the concave plate 307 at its lowest point, and the grippers 301 unfold to facilitate the picking up of the lead screw body 6. When clamping is required, the nut seat 304 first moves towards the clamping mechanism, and the first limiting post engages at the bottom of the hook-shaped groove 8, driving the concave plate 307 and the grippers 301 to move synchronously. Meanwhile, the second limiting post 308 of the concave plate 307 moves upward along the inclined groove of the path groove, causing the concave plate 307 to move horizontally and simultaneously upward relative to the grippers 301, thus facilitating the clamping... The jaw 301 gradually clamps the lead screw body 6. At this time, the second limiting post 308 enters the horizontal groove of the path groove, which can keep the jaw 301 clamped and allow horizontal displacement, so that the lead screw body 6 can be axially fed. When the second limiting post 308 moves to the end of the horizontal groove, the feed of the lead screw body 6 is completed. At this time, the vertical groove of the path groove is aligned with the vertical groove of the hook groove 8, so that under the action of gravity, the second limiting post 308 descends along the vertical groove, and the first limiting post also descends along the vertical groove of the hook groove 8, so that the concave plate 307 descends, the jaw 301 releases the lead screw body 6, and the lead screw body 6 can be clamped by the clamping mechanism and rotated for turning. This realizes the function of automatically clamping the lead screw body 6 and automatically releasing it after axial displacement. There is no need to set up an additional drive mechanism, such as a cylinder, thereby avoiding additional technical problems. The structure is simple and saves costs.

[0065] When the lead screw body 6 is finished and needs to be reset, the nut seat 304 is reset in the opposite direction. The displacement of the hook groove 8 drives the first limiting post to rise along the inner inclined groove and the second outer limiting post 308 to rise along the vertical groove of the path groove, which makes the limiting plate 302 rise. The gripper 301 then clamps the lead screw body 6 again and can then reset it. In other words, it is only necessary to drive the nut seat 304 to move horizontally to achieve automatic control of the gripper 301, so that it can make corresponding actions at the appropriate time, with a high degree of automation.

[0066] The clamping mechanism also includes a three-jaw chuck 4, with a feed port through the center of the three-jaw chuck 4.

[0067] Preferably, a feed port is provided through the center of the three-jaw chuck 4, so that the long lead screw body 6 can be clamped and fixed. The three-jaw chuck 4 is a common existing technology in the field of turning, so it will not be described in detail here.

[0068] Preferably, when it is necessary to drive the three-jaw chuck 4 to rotate, the turning function can be achieved by the gear set transmission and then the motor assembly driving the gear set to rotate.
