Description

Technical Field

[0001] The present invention relates to the technical field of vertical machining centers, and in particular to a loading and cutting integrated device for a vertical machining center assembly. Background Art

[0002] The core motion axes (X / Y / Z axes) of a vertical machining center rely on lead screws to convert the rotational motion of the servo motor into precise linear motion of the worktable or spindle. Therefore, the lead screw is an essential transmission component in a vertical machining center. The lead screw must be reliably connected to the output shaft or reduction mechanism of the servo motor through a shaft end connection structure. Therefore, during the production and processing of the lead screw, the shaft end of the lead screw needs to be machined into a connection structure. Typically, typical structures are achieved through turning. For example, the threaded end connection, which is the most common threaded end connection in the lead screw of a vertical machining center, requires turning the shaft end of the lead screw into an external thread for installing a lock nut or coupling.

[0003] However, due to the overall large size of the vertical machining center equipment, the length of the screw rod also increases. In the existing lathe equipment, the clamping length of the ordinary three-jaw chuck is limited, making it difficult to turn longer screw rods. If the clamping length is too long, the screw rod axis will deviate from the rotation center during the turning process, causing shaking, and the longer screw rod is also difficult to load stably by manual means.

[0004] Therefore, it is necessary to provide an integrated loading and cutting device that can stably turn long-sized screw rods and facilitate rapid loading and unloading of the screw rods. Summary of the Invention

[0019] See also Figure 1-8 The present invention provides a technical solution: a vertical machining center assembly loading and cutting integrated equipment, including a loading rack 1 and a cutting mechanism 2, The cutting mechanism 2 is set to be open and connected to the loading rack 1; The cutting mechanism 2 includes a clamping mechanism that can be penetrated by the screw body 6 and a feeding mechanism 3 that drives the screw body 6 to feed axially. The loading rack 1 screens the screw body 6 and feeds it to the feeding mechanism 3. The feeding mechanism 3 drives the axial end of the screw body 6 through the clamping mechanism to the cutting station. The clamping mechanism clamps the screw body 6 and rotates it for cutting processing.

[0020] Preferably, the cutting mechanism 2 is open, so that it is convenient to cooperate with the feeding rack 1 and can accommodate longer screw bodies 6 for cutting. Specifically, a batch of screw bodies 6 to be processed are placed on the feeding rack 1, and a single screw body 6 is screened out by the feeding rack 1 and loaded onto the feeding mechanism 3. The feeding mechanism 3 drives the current screw body 6 to axially displace, so that the screw body 6 passes through the clamping mechanism, and the shaft end to be processed passes through the clamping mechanism and extends to the cutting station on the other side. The cutting station is equipped with a corresponding turning tool assembly (the turning tool assembly is a prior art in this field, so it 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 realize the turning processing of the shaft end, and then the screw body 6 is driven to axially reset by the feeding mechanism 3, and the screw body 6 is unloaded by the loading rack 1, and the subsequent screw body 6 is screened and loaded, so as to realize the integrated production of loading and cutting of the long-specification screw body 6. The through-type clamping mechanism and the open cutting mechanism 2 can realize stable cutting of the long-specification screw body 6, and cooperate with the loading rack 1 to further facilitate the convenient loading of the long-specification screw body 6.

[0021] The cutting mechanism 2 further comprises at least one set of supporting parts 201 , which receive the screw body 6 for screening and feeding the material and align it with the clamping mechanism.

[0022] Preferably, the screw rod body 6 for screening and loading on the loading rack 1 first falls onto the support part 201 for limited support. In this embodiment, two groups of support parts 201 are provided to support the two sides of the long-specification screw rod body 6 respectively, and align its axis with the axis of the clamping mechanism to facilitate subsequent passage through the clamping mechanism.

[0023] The loading rack 1 is tilted as a whole and includes an L-shaped loading plate 101 . Several screw bodies 6 to be processed are arranged in sequence in the L-shaped loading plate 101 . A pair of liftable loading blocks 102 are provided at one end of the L-shaped loading plate 101 .

[0024] Preferably, according to the rolling characteristics of the screw body 6 and the effect of gravity, the loading rack 1 is set to an overall inclined angle, and a number of screw bodies 6 to be processed are arranged in sequence and confined in the L-shaped loading plate 101. When loading is required, a pair of lifting blocks 102 move upward to lift the screw body 6 at the end. Under the action of gravity, the screw body 6 rolls downward, can be separated from the L-shaped loading plate 101, and fall onto the feeding mechanism 3, and the screening and loading function can be completed; Preferably, the ejector block 102 can be driven by a cylinder assembly; Preferably, when the screw body 6 falls onto the feeding mechanism 3 , its two ends are supported by the two groups of support parts 201 , which limit the position of the screw body 6 and facilitate axial feeding in cooperation with the feeding mechanism 3 .

[0025] A blanking rack 103 is provided at one end of the L-shaped loading plate 101 , and the feeding mechanism 3 is provided at the starting end of the blanking rack 103 .

[0026] Preferably, a blanking rack 103 is connected to the end of the L-shaped loading plate 101. When the screw body 6 is processed, the screw body 6 is rolled onto the blanking rack 103 to store the processed screw body 6.

[0027] A pair of transition plates 104 are provided at the starting end of the blanking rack 103 , and the transition plates 104 are connected to the ends of the L-shaped loading plate 101 .

[0028] Preferably, a transition plate 104 is provided to connect the L-shaped loading plate 101 and the support portion 201 , so that the screw body 6 can roll along the transition plate 104 and transition to the support portion 201 under the lifting action of the ejection block 102 .

[0029] The support portion 201 includes a pair of support seats 202 . A support roller 203 and a pair of support wheels 204 are provided at the upper ends of the support seats 202 . A brake clamp 205 is provided on one side of the support roller 203 .

[0030] Preferably, the support portion 201 is preferably configured as a support roller 203 and a support wheel 204. Under the transition action of the transition plate 104, the screw body 6 rolls between the two. Under the premise of ensuring that the axis of the screw body 6 is aligned, adaptive rolling can also be performed to facilitate stable support when the screw body 6 rotates; Preferably, a brake plate 205 is provided on one side of the support roller 203 , and the brake plate 205 further prevents the screw body 6 from being separated from between the support roller 203 and the support wheel 204 due to the rolling inertia along the transition plate 104 .

[0031] A liftable inclined block 206 is provided between the pair of support wheels 204 , and the inclined block 206 lifts up the screw body 6 .

[0032] Preferably, when the lead screw body 6 is completed, a beveled block 206 is arranged between a pair of supporting wheels 204, and the upper side of the beveled block 206 is matched with the slope of the brake plate 205. When the beveled block 206 is lifted upward, the lead screw body 6 is lifted upward, and the lead screw body 6 rolls along the slope until the brake plate 205 is contacted, and then the lead screw body 6 rolls over the brake plate 205 and falls on the material rack 103. At the same time, the material lifting block 102 lifts the next lead screw body 6 for feeding, so that the feeding and unloading are synchronized, and the processing convenience is improved. Preferably, an electric telescopic cylinder is arranged in the supporting seat 202 to drive the beveled block 206.

[0033] The feeding mechanism 3 comprises a pair of clamping jaws 301, the lower ends of the clamping jaws 301 are hingedly connected, and the lower sides of the clamping jaws 301 are provided with a linear driving mechanism.

[0034] Preferably, a pair of clamping jaws 301 are arranged to be hingedly opened and closed, so as to clamp the lead screw body 6, and the linear driving mechanism is used to drive the axial displacement of the lead screw body 6. When the lead screw body 6 is fed or unloaded, the clamping jaws 301 are fully expanded, so that the height of the clamping jaws 301 is lower than the height of the brake plate 205, thereby not affecting the rolling feeding and unloading of the lead screw body 6. Preferably, the linear driving mechanism includes but is not limited to a screw rod mechanism, a gear and rack mechanism, or a cylinder driving member. Preferably, when the clamping jaws 301 need to be controlled to open and close, a pair of limiting plates 302 are arranged on both sides of the clamping jaws 301 and are in a vertical state. When the pair of limiting plates 302 are lifted relative to the clamping jaws 301, the pair of clamping jaws 301 are driven to open and close. Specifically, the height of the clamping jaws 301 remains unchanged, and the outer side of the clamping jaws 301 is provided with a plane. When the limiting plate 302 is lifted relative to the clamping jaws 301, the clamping jaws 301 are lifted upward along the plane until the pair of clamping jaws 301 clamp the lead screw body 6. Conversely, when the limiting plate 302 is lowered, the clamping jaws 301 are expanded under the action of gravity. The structure design is simple, and the opening and closing control of the hinged connection can be realized without multiple gear meshing, which has strong practicability. Preferably, a rotating rod is arranged at the upper end of the limiting plate 302, so as to further reduce the friction force of the limiting plate 302 pushing the clamping jaws 301 to open and close, and improve the service life. Preferably, the linear drive mechanism includes a threaded rod 303, which passes through and is threadedly connected to a nut seat 304. Concave frames 305 are provided at both ends of the clamping jaw 301. The concave frames 305 are provided on the upper side of the nut seat 304. A pair of guide side plates 306 are provided between the pair of support seats 202 to guide the displacement of the nut seat 304. The threaded rod 303 is driven to rotate by the motor 7 to drive the clamping jaw 301 to perform a linear reciprocating displacement, thereby realizing the axial feed of the screw body 6. Preferably, the lower ends of the pair of limiting plates 302 are fixedly connected with concave plates 307, and the inner sides of the limiting plates 302 slide up and down with the concave frames 305, while the lower sides of the guide side plates 306 are hollowed out to facilitate the up and down displacement of the concave plates 307. Optionally, due to limited installation space, a driving member can only be provided on the lower side of the concave plates 307. A cylinder assembly can be optionally provided on the lower side of the concave plates 307 to drive the concave plates 307 to move up and down. Alternatively, since in the above embodiment, a driving cylinder assembly needs to be provided on the lower side of the concave plate 307 for driving, the concave plate 307 itself needs to follow the clamping jaw 301 for reciprocating displacement, which makes the cylinder assembly itself in an unstable state, and the cylinder needs to be connected to an air pipe, which bends, stretches or drags with the movement, greatly affecting the service life. Therefore, hook-shaped grooves 8 are provided on both sides of the nut seat 304, and a limiting post 1 is provided in the hook-shaped groove 8. The limiting post 1 is connected to the inner side of the concave plate 307, and the lower end of the concave frame 305 is slidably matched 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 oblique groove of the hook-shaped groove 8 limits the limiting post 1 to move, which can make the limiting post 1 move upward or downward along the oblique groove, so that the limiting plate 302 can drive the clamping jaw 301 upward to clamp or downward to release the clamping jaw 301; A path groove is provided on the upper through hole of the guide side plate 306, and a limiting column II 308 is provided in the path groove, and the limiting column II 308 is connected to the outer side of the concave plate 307. When 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 limiting column I is at the bottom of the hook-shaped groove 8, and the limiting column II 308 is at the bottom of the inclined groove of the path groove. At this time, the concave plate 307 is in the lowest position, and the clamping jaws 301 are spread apart, thereby facilitating the clamping of the screw rod body 6. When clamping is needed, the nut seat 304 is first displaced towards the clamping mechanism. The limiting column I is clamped at the bottom of the hook-shaped groove 8, and the concave plate 307 and the clamping jaws 301 are synchronously displaced. The limiting column II 308 of the concave plate 307 is displaced upward along the inclined groove of the path groove, so that the concave plate 307 is horizontally displaced, and at the same time, it is also displaced upward relative to the clamping jaws 301, so that the clamping jaws 301 gradually clamp the screw rod body 6. At this time, the limiting column II 308 enters the horizontal groove part of the path groove, so that the clamping jaws 301 can be kept in the clamped state for horizontal displacement, so that the screw rod body 6 is axially fed. When the limiting column II 308 is displaced to the end of the horizontal groove, the feeding of the screw rod body 6 is completed. At this time, the vertical groove part of the path groove is aligned with the vertical groove of the hook-shaped groove 8, so that under the action of gravity, the limiting column II 308 descends along the vertical groove, and the limiting column I also descends along the vertical groove of the hook-shaped groove 8, so that the concave plate 307 descends, and the clamping jaws 301 release the screw rod body 6. The screw rod body 6 can be clamped by the clamping mechanism and rotated for turning, so as to realize the function of automatic clamping and automatic release after axial displacement of the screw rod body 6. No additional driving mechanism, such as a cylinder, is needed, thereby avoiding the generation of additional technical problems, and the structure is simple and cost-saving. When the screw rod body 6 is machined and needs to be reset, the nut seat 304 is reset in the opposite direction, the hook-shaped groove 8 is displaced, the limiting column I is driven to ascend along the inner inclined groove, and the outer limiting column II 308 is driven to ascend along the vertical groove of the path groove, so as to ascend the limiting plate 302, and the clamping jaws 301 clamp the screw rod body 6 again. Then, the screw rod body 6 can be reset, that is, only the horizontal displacement of the nut seat 304 is needed, so as to automatically control the clamping jaws 301 to make corresponding actions at corresponding times, thereby achieving high automation.

[0035] The clamping mechanism further comprises a three-jaw chuck 4, and a feeding port is provided in the center of the three-jaw chuck 4.

[0036] Preferably, the feeding port is provided in the center of the three-jaw chuck 4, so as to clamp and fix the long-specification screw rod body 6. The three-jaw chuck 4 is a common prior art in the field of turning machining, and therefore will not be described in detail here. Preferably, when the three-jaw chuck 4 needs to be driven to rotate, the gear set is driven to rotate by the motor assembly, so as to realize the turning function.
