Description

Technical Field

[0001] This utility model belongs to the technical field of gear processing equipment, specifically relating to a positioning and adjustment module structure for a gear shaper worktable. Background Technology

[0002] Gear shaper is one of the core pieces of equipment in gear processing. Its worktable is used to support the gear blank to be processed. The positioning accuracy of the worktable directly affects the processing accuracy of the gear (such as pitch error and tooth profile accuracy).

[0003] The positioning and adjustment structure of the traditional gear shaper worktable is adjusted by tightening bolts or manually adjusting screws. During the adjustment process, gaps are prone to occur, and it is difficult to achieve linear and precise displacement, which leads to the displacement of the blank position during processing and affects the gear processing quality. The connection between the worktable and the adjustment mechanism is mostly fixed by a single bolt, which is prone to loosening after long-term stress. Moreover, it is difficult to ensure the coaxiality or flatness of the worktable and the adjustment mechanism during installation.

[0004] Therefore, there is an urgent need for a positioning and adjustment module structure for a gear hobbing machine worktable that can overcome the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning and adjustment module structure for a gear hobbing machine worktable to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and adjustment module structure for a gear hobbing machine worktable, comprising a positioning and adjustment mechanism, wherein a gear hobbing machine worktable is fixedly connected to the top of the positioning and adjustment mechanism, the positioning and adjustment mechanism comprising a support adjustment component and a support platform fixedly connected to the bottom of the gear hobbing machine worktable, both sides of the top of the support platform having a sliding groove, a guide rod fixedly connected to the inner wall of the sliding groove, a support adjustment component slidably connected to the guide rod, a slag discharge port being provided at the bottom of the sliding groove, and a slag collection component for use with the slag discharge port being fixedly connected to the bottom of the support platform;

[0007] The support adjustment assembly includes a fixed block and a support mounting frame fixedly connected to the bottom of the gear hobbing machine's worktable. The top of the support mounting frame has a square groove for inserting the fixed block. Fixed screws are threaded to the four corners of the support mounting frame. One end of the fixed screw passes through the support mounting frame and extends into the square groove. A slide cylinder that is slidably connected to the guide rod is fixedly connected to the bottom of the support mounting frame. An electric push rod is fixedly connected to the front of the support mounting frame. The fixed block has an internal threaded hole that cooperates with the fixed screw.

[0008] Using the above scheme, the sliding cooperation of the guide rod and the slide cylinder restricts the movement direction of the support adjustment component to linear, avoiding lateral deviation during the adjustment process. The electric push rod provides stable driving force, and the precise displacement of the worktable can be achieved by controlling the extension and retraction of the electric push rod. The fixed end of the electric push rod is fixedly connected to the front top of the support table, and the output end is fixedly connected to the support mounting bracket. The electric push rod adopts a trapezoidal screw drive structure, which can maintain its position after power failure and has self-locking properties. The four fixing blocks fixedly connected to the bottom of the gear hobbing machine's worktable are inserted into the corresponding square slots. This method allows for quick positioning and facilitates subsequent use of the fixing screws and fixing blocks at the four corner positions. The internal threaded connection is locked, which reduces the installation gap by matching the square groove with the fixing block, and the fixing screws at the four corners are locked simultaneously to prevent the gear shaper worktable from warping or loosening under stress. This connection and fixing method also has the advantage of high flexibility, as the gear shaper worktable can be removed separately for maintenance or replacement. There is a slag discharge port at the front and rear ends of the bottom of the sliding grooves on both sides of the top of the support platform, with two on each side of the sliding groove, for a total of four slag discharge ports on both sides of the sliding groove. A slag collection component can collect slag from two slag discharge ports in the same horizontal direction at the same time. When adjusting the front and rear position of the gear shaper worktable, the residual waste in the sliding groove can be treated to avoid the accumulation of waste.

[0009] In the above scheme, it should be noted that the electric actuator is electrically connected to an external power source.

[0010] In a preferred embodiment, the bottom of the support platform is fixedly connected with several support legs, and the slag collection assembly is located directly below the slag discharge port.

[0011] Using the above scheme, the support legs support the support platform to prevent the support platform from directly contacting the ground. Several support legs are evenly distributed at the bottom of the support platform to provide stable support and ensure that the waste residue in the chute can fall directly into the slag collection component after passing through the slag discharge port, thus preventing the waste residue from shifting or being missed.

[0012] In a preferred embodiment, the number of square slots and fixing blocks on the top of the support mounting bracket are the same, and the square slots and fixing blocks are interference-fitted.

[0013] Using the above scheme, the corresponding number of square slots and fixing blocks installed meet the requirements for stable support, facilitate quick positioning during installation, and the interference fit eliminates the installation gap between the fixing block and the square slot, thereby improving the coaxiality of the gear hobbing machine's worktable and the support mounting frame.

[0014] In a preferred embodiment, the support mounting frame is composed of two support base plates and a trapezoidal support frame, with the trapezoidal support frame fixedly connected between the two support base plates.

[0015] By adopting the above scheme, the trapezoidal support frame has better stability, and the two support base plates are located on both sides to avoid excessive local deformation under stress.

[0016] In a preferred embodiment, the slag collection assembly includes an internally threaded cylinder fixedly connected to the bottom of the support platform, a connecting screw threadedly connected to the end of the internally threaded cylinder away from the support platform, and a collection box fixedly connected to the end of the connecting screw away from the internally threaded cylinder.

[0017] Using the above method, when the collection box is full of waste residue, rotating the collection box will unscrew the connecting screw from the internal threaded cylinder, making it easy to clean the waste residue.

[0018] In a preferred embodiment, the top of the collection box is provided with a collection groove, which corresponds to the slag discharge port at the bottom of the positioning adjustment mechanism chute.

[0019] By adopting the above scheme, it is ensured that the waste residue in the support platform chute can fall into the collection tank.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The sliding cooperation of the guide rod and the slide cylinder restricts the movement direction of the support adjustment component to linear, avoiding lateral deviation during the adjustment process. The electric push rod provides stable driving force, and the precise displacement of the worktable is achieved by controlling the extension and retraction of the electric push rod. During installation, the square groove of the support mounting bracket is interference-fitted with the fixing block to eliminate installation gaps. It is locked by the fixing screws at the corresponding positions, which can withstand greater loads and ensure that the gear hobbing machine worktable does not loosen during long-term use. This connection and fixing method also has the advantage of high flexibility, and the gear hobbing machine worktable can be removed separately for maintenance or replacement.

[0022] The slag discharge port at the bottom of the support platform chute pushes the debris in the chute as the sliding cylinder slides back and forth on the guide rod. The debris moves towards the slag discharge ports on both sides of the bottom of the chute and finally falls into the corresponding slag collection component below. Timely cleaning of debris can prevent debris accumulation from hindering the sliding of the support adjustment component and scratching the guide rod. The slag collection component is simple to use and only requires regular maintenance and cleaning. The number of components installed at the corresponding positions can ensure the collection effect.

[0029] Please see Figure 1-5 This utility model provides a positioning adjustment module structure for a gear hobbing machine worktable, including a positioning adjustment mechanism 1. The top of the positioning adjustment mechanism 1 is fixedly connected to a gear hobbing machine worktable 2. The positioning adjustment mechanism 1 includes a support adjustment component 13 and a support platform 11 fixedly connected to the bottom of the gear hobbing machine worktable 2. Slide grooves are provided on both sides of the top of the support platform 11. A guide rod 12 is fixedly connected to the inner wall of the slide groove. The support adjustment component 13 is slidably connected to the guide rod 12. A slag discharge port is provided at the bottom of the slide groove. A slag collection component 14 for use with the slag discharge port is fixedly connected to the bottom of the support platform 11.

[0030] The support adjustment assembly 13 includes a fixing block 132 and a support mounting frame 131 fixedly connected to the bottom of the gear hobbing machine worktable 2. The top of the support mounting frame 131 is provided with a square groove for inserting the fixing block 132. The four corners of the support mounting frame 131 are threaded with fixing screws 134. One end of the fixing screw 134 passes through the support mounting frame 131 and extends into the square groove. The bottom of the support mounting frame 131 is fixedly connected with a slide cylinder 133 that is slidably connected to the guide rod 12. The front of the support mounting frame 131 is fixedly connected with an electric push rod 135. The fixing block 132 is provided with an internal threaded hole that cooperates with the fixing screw 134.

[0031] The sliding engagement of guide rod 12 and slide cylinder 133 restricts the movement direction of support adjustment component 13 to linearity, preventing lateral offset during adjustment. Electric push rod 135 provides stable driving force, and precise displacement of the worktable can be achieved by controlling the extension and retraction of electric push rod 135. The fixed end of electric push rod 135 is fixedly connected to the front top of support table 11, and the output end is fixedly connected to support mounting bracket 131. Electric push rod 135 adopts a trapezoidal screw drive structure, which can maintain its position after power failure and has self-locking properties. The four fixing blocks 132, which are fixedly connected to the bottom of gear hobbing machine worktable 2, are inserted into the corresponding square slots. This method allows for quick positioning and facilitates subsequent use of fixing screws 134 at the four corners. The screw threaded connection with the internal threaded hole of the fixing block 132 is locked. On the one hand, the cooperation between the square groove and the fixing block 132 reduces the installation gap. On the other hand, the fixing screws 134 located at the four corners are locked simultaneously to prevent the gear shaping machine worktable 2 from warping or loosening after being subjected to force. This connection and fixing method also has the advantage of high flexibility. The gear shaping machine worktable 2 can be removed separately for maintenance or replacement. A slag discharge port is opened at the front and rear ends of the bottom of the sliding groove on both sides of the top of the support platform 11. There are two slag discharge ports on each side of the sliding groove, and a total of four slag discharge ports on both sides of the sliding groove. A slag collection component 14 can collect slag from two slag discharge ports in the same horizontal direction at the same time. When adjusting the front and rear position of the gear shaping machine worktable 2, the residual waste in the sliding groove can be treated to avoid the accumulation of waste.

[0032] Several support legs are fixedly connected to the bottom of the support platform 11, and the slag collection assembly 14 is located directly below the slag discharge port.

[0033] The support legs support the support platform 11 to prevent the support platform 11 from directly contacting the ground. Several support legs are evenly distributed at the bottom of the support platform 11 to provide stable support and ensure that the waste residue in the chute can fall directly into the slag collection component 14 after passing through the slag discharge port, thus preventing the waste residue from shifting or being missed.

[0034] The number of square slots and fixing blocks 132 on the top of the support mounting bracket 131 are the same, and the square slots and fixing blocks 132 are interference fit;

[0035] The corresponding number of square slots and fixing blocks 132 installed meet the requirements for stable support, facilitate quick positioning during installation, and the interference fit eliminates the installation gap between the fixing block 132 and the square slot, thereby improving the coaxiality between the gear hobbing machine worktable 2 and the support mounting frame 131.

[0036] The support mounting frame 131 is composed of two support base plates and a trapezoidal support frame, with the trapezoidal support frame fixedly connected between the two support base plates;

[0037] The trapezoidal support frame has better stability, and the two support base plates are located on both sides to avoid excessive local deformation under stress.

[0038] The slag collection assembly 14 includes an internally threaded cylinder 143 fixedly connected to the bottom of the support platform 11. A connecting screw 142 is threadedly connected to the end of the internally threaded cylinder 143 away from the support platform 11, and a collection box 141 is fixedly connected to the end of the connecting screw 142 away from the internally threaded cylinder 143.

[0039] When the collection box 141 is full of waste residue, rotate the collection box 141 to unscrew the connecting screw 142 from the internal threaded cylinder 143 for easy cleaning of the waste residue.

[0040] The top of the collection box 141 is provided with a collection groove, which corresponds to the slag discharge port in the top sliding groove of the positioning adjustment mechanism 1;

[0041] Ensure that the waste residue in the chute of support platform 11 falls into the collection tank.

[0042] In use, when the position of the gear shaping machine's worktable 2 needs to be adjusted, a command is sent to the electric push rod 135 via an external controller. The electric push rod 135 extends or retracts according to the command. The extension of the output end of the electric push rod 135 drives the slide cylinder 133 to slide on the guide rod 12 within the slide groove, thereby moving the gear shaping machine's worktable 2. When the worktable reaches the preset position, the electric push rod 135 stops extending and maintains its position through its self-locking mechanism, achieving precise positioning and fixation of the gear shaping machine's worktable 2. During this process, the precise fit between the guide rod 12 and the slide cylinder 133 restricts the lateral displacement of the support mounting bracket 131. The interference fit between the fixing block 132 and the square groove, and the locking of the fixing screw 134, ensure the gear shaping... There is no relative displacement between the machine worktable 2 and the support mounting frame 131. Some metal shavings generated during gear machining by the gear hobbing machine will fall from the worktable 2 into the slide groove on the top of the support table 11 due to gravity. The shavings in the slide groove are pushed by the slide cylinder 133 sliding on the guide rod 12 and fall into the slag collection assembly 14 below through the corresponding slag discharge port. The collection groove on the top of the collection box 141 is precisely aligned with the slag discharge port, and the shavings fall directly into the collection groove. The operator can clean the collected shavings regularly. Rotating the collection box 141 separates the connecting screw 142 and the internal threaded cylinder 143, and the collection box 141 can be removed for cleaning. After cleaning, the connecting screw 142 is screwed back in to resume use. It is simple, convenient and worry-free to use.
