Description

Technical Field

[0001] This utility model belongs to the field of parts processing technology, specifically relating to a positioning and guiding device for a tapping machine. Background Technology

[0002] In existing universal tapping machines, the drive mechanism is mounted on a connecting platform and connected to the machine body via a support platform. The support platform achieves rotational movement of the connecting platform in the horizontal plane through a vertically arranged bearing-shaft structure; the pitching movement of the connecting platform is achieved through the rotation between the rotating plate structure and the connecting platform, thus enabling the drive mechanism mounted on the connecting platform to perform universal tapping. Although this structure can achieve universal tapping, the bearing-shaft structure on the support platform lacks a self-locking function. When tapping in a non-vertical state, the rotation of the drive mechanism around the bearing-shaft structure cannot be restricted. This means that the perpendicularity of the drive mechanism's spindle module's rotation axis to the drilling surface depends entirely on the operator's assistance, which is detrimental to ensuring the perpendicularity of the tapped thread and makes it highly susceptible to tap breakage due to axis misalignment during tapping. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a positioning and guiding device for a tapping machine, which can keep the spindle module of the tapping machine perpendicular to the drilling surface, thereby improving the tapping accuracy.

The bracket has a mounting hole for the tapping machine's spindle module to pass through, and a locking assembly for locking the spindle module to the bracket is provided at the mounting hole. The slide is slidably mounted on the bracket and has a guide hole. The guide hole is parallel to the axis of the mounting hole, and the sliding direction of the slide is perpendicular to the axis of the mounting hole. The outer diameter of the positioning rod is adapted to the guide hole, and during operation, the positioning rod passes through the guide hole and forms a guiding limit.

[0005] In a preferred embodiment of the present invention, the bracket is provided with a slot communicating with the mounting hole, the slot extending to the edge of the bracket; the locking assembly uses the slot to cause the mounting hole to shrink and deform to lock the spindle module.

[0006] Preferably, the bracket is provided with a locking hole at the corresponding position of the slot, and the locking assembly includes a locking member, which is threadedly engaged with the locking hole.

[0007] In a preferred embodiment of this utility model, the bracket is provided with a first guide structure, and the slide is provided with a second guide structure. The first guide structure and the second guide structure are adapted to form a sliding guide for the slide.

[0008] Preferably, the first guide structure includes a guide rail protruding on one side of the bracket, and the second guide structure includes a slider disposed on one side of the slide block, the slider cooperating with the guide rail.

[0009] In a preferred embodiment of this utility model, the slide block has an inner cavity that extends vertically, and a sliding sleeve is provided in the inner cavity, the inner hole of the sliding sleeve forming the guide hole.

[0010] Preferably, the sliding sleeve includes a base plate and a sleeve body, the base plate being located at the bottom of the sleeve body; the sleeve body being located in the inner cavity of the slide block, and the base plate being located on the lower side of the slide block and locked to the bottom of the slide block.

[0011] In a preferred embodiment of this utility model, the positioning rod includes multiple splicing rods, which are detachably connected and combined to form the positioning rod.

[0012] Preferably, in two adjacent splicing rods, one splicing rod has a connecting hole at its end, and the other splicing rod has a connecting section at its end, the connecting section being threaded into the connecting hole.

[0013] Preferably, the end of the positioning rod away from the slide is provided with a positioning part, which is adapted to a positioning hole that has been machined on the drilling surface and is parallel to the axis of the hole to be tapped.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a tapping positioning and guiding device. A locking assembly secures the tapping machine's spindle module within the mounting hole of a bracket. Simultaneously, one end of a positioning rod is inserted into another hole on the drilling surface where the tapped hole is located. These holes can be pre-machined threaded holes or positioning holes serving a positioning function. The guide hole on the slide is adapted to the positioning rod, allowing the bracket to rise and fall with the spindle module.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figures 1-3This embodiment discloses a positioning and guiding device for a tapping machine, including a bracket 1, a slide 3, and a positioning rod 4. The bracket 1 has a mounting hole 5 through which the spindle module 2 of the tapping machine passes, and a locking component for locking the spindle module 2 to the bracket 1 is provided at the mounting hole 5. The slide 3 is slidably mounted on the bracket 1, and has a guide hole 16 on the slide 3. The guide hole 16 is parallel to the axis of the mounting hole 5, and the sliding direction of the slide 3 is perpendicular to the axis of the mounting hole 5. The outer diameter of the positioning rod 4 is adapted to the guide hole 16. During operation, the positioning rod 4 passes through the guide hole 16 and forms a guiding limit. One end of the positioning rod 4 is inserted into other holes on the drilling surface where the hole to be tapped is located, and these holes are parallel to the axis of the hole to be tapped. Therefore, the positioning rod 4 can be used to guide and limit the spindle module 2 of the tapping machine, ensuring that the spindle module 2 remains perpendicular to the drilling surface and ensuring tapping accuracy.

[0023] Furthermore, the bracket 1 is provided with a slot 6 communicating with the mounting hole 5, and the slot 6 extends to the edge of the bracket 1; the locking assembly uses the slot 6 to cause the mounting hole 5 to shrink and deform to lock the spindle module 2. In this embodiment, the mounting hole 5 can be set as rectangular, circular, etc., and should correspond to the housing of the tapping machine's spindle module 2 or other parts that are easy to fix, so as to lock the spindle module 2. For example, the housing of the tapping machine's spindle module 2 can be inserted into the mounting hole 5, and the housing can be locked and fixed without affecting the tapping action of the spindle.

[0024] To better adapt to the locking assembly, locking holes are provided at the corresponding positions of the bracket 1 and the slot 6 in this embodiment. The locking assembly includes a locking member 7, which is threadedly engaged with the locking hole. Specifically, the locking hole in this embodiment can be a threaded hole, and the locking member 7 can be a bolt. The locking hole extends through both sides of the slot 6, and the locking member 7 uses the threaded engagement with the locking hole to tighten or loosen the portions on both sides of the slot 6, thereby causing the mounting hole 5 to lock or loosen the spindle module 2. In addition, a step can generally be provided at one end of the locking hole as a limit to restrict the head of the locking member 7, so that the locking member 7 can smoothly control the locking or loosening of the spindle module 2.

[0025] Furthermore, the bracket 1 is provided with a first guide structure, and the slide 3 is provided with a second guide structure. The first guide structure and the second guide structure are adapted to form a sliding guide for the slide 3. In this embodiment, the first guide structure includes a guide rail 9 protruding on one side of the bracket 1, and the second guide structure includes a slider 12, which is disposed on one side of the slide 3. The slider 12 and the guide rail 9 cooperate with each other. Specifically, the guide rail 9 can be assembled on the bracket 1 using screws, bolts, or other parts. Of course, the slide 3 and the slider 12 can also be locked and fixed together in the same way. For specific implementations of the guide rail 9 and the slider 12, please refer to the prior art. Through their cooperation, both the slide 3 and the bracket 1 are slidable, and the sliding guide limit of the slide 3 is achieved, ensuring sliding accuracy.

[0026] As another implementation of the first and second guide structures, one can be a groove and the other can be a protrusion. The cooperation between the two can also achieve sliding and guiding limit, such as the cooperation between a dovetail groove and a dovetail protrusion.

[0027] In this embodiment, the slide block 3 has a through-cavity 13, and a sliding sleeve 10 is provided in the cavity 13. The inner hole of the sliding sleeve 10 forms a guide hole 16. In this embodiment, the sliding sleeve 10 can be made of copper or the like. The sliding sleeve 10 includes a base plate 15 and a sleeve body 14. The base plate 15 is located at the bottom of the sleeve body 14; the sleeve body 14 is located in the cavity 13 of the slide block 3, and the base plate 15 is located on the lower side of the slide block 3 and is locked to the bottom of the slide block 3. In this embodiment, the base plate 15 and the bottom of the slide block 3 can be assembled and fixed together using screws, bolts, or other parts.

[0028] In this embodiment, the positioning rod 4 can be formed by combining multiple splicing rods, which can be detachably connected. This allows the length of the positioning rod 4 to be flexibly adjusted, facilitating adaptive configuration based on the workpiece requirements during use. Specifically, in two adjacent splicing rods, one end of the splicing rod has a connecting hole, and the end of the other splicing rod has a connecting section, which is threaded into the connecting hole. The connecting hole can be a threaded hole with an internal thread structure, and the connecting section can be machined with an external thread structure, thereby achieving a threaded fit between the two. This connection method between the splicing rods is both simple and convenient.

[0029] Furthermore, in this embodiment, the end of the positioning rod 4 furthest from the slide block 3 is provided with a positioning part 11, which is adapted to a positioning hole that has been machined on the drilling surface and is parallel to the axis of the hole to be tapped. A hexagonal head bolt 17 is provided at the end of the positioning rod 4 near the slide block 3. Specifically, during machining, the positioning part 11 of the positioning rod 4 is inserted into the positioning hole. To improve the stability of the positioning rod 4, the positioning part 11 can be configured as a magnet, a threaded structure, etc., so that it can be adapted to the positioning hole while maintaining a more stable position; the positioning hole can be a threaded bottom hole or other holes on the drilling surface. A threaded hole is provided at the end of the positioning rod 4 to cooperate with the hexagonal head bolt 17, which allows the positioning rod 4 to be easily pulled out of the positioning hole.

[0030] Furthermore, in this embodiment, a laser sensor 8 can be installed on the bracket 1 to measure the depth of the hole to be tapped, thereby improving tapping accuracy. The laser sensor 8 can be associated with the controller of the tapping machine to realize real-time distance measurement, tapping progress monitoring, etc.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
