Description

Technical Field

[0001] The present application relates to the field of gear shaping machines, and in particular to a variable worktable for gear shaping machines. Background Art

[0002] A gear shaping machine is a metal cutting machine tool that uses a gear shaping cutter to process internal and external spur and helical cylindrical gears and other toothed parts according to the generating method.

[0003] In the related technology, the gear shaping machine generally needs to lift the workpiece to a certain height to facilitate the processing of the tooth shape. The common processing method is to use a metal block to pad under the workpiece, but this method is time-consuming and labor-intensive, and the precision is not high. There are also special workbenches for assisting gear shaping machines, but they can generally only adapt to workpieces of a single size and are not very applicable. Utility Model Content

[0004] In order to improve the applicability of the workbench, the present application provides a variable workbench for a gear shaping machine.

[0005] The present application provides a variable worktable for a gear shaping machine, which adopts the following technical solution:

[0006] A variable worktable for a gear shaping machine comprises a base for connecting to a machine tool, characterized in that: a plurality of sliders are arranged along a circular trajectory above the base, each slider is slidably connected to the base along the radial direction of the arrangement trajectory, a positioning groove is provided on the upper end of the slider, the positioning grooves extend along the sliding direction of the corresponding slider, a positioning rod is provided in the positioning groove, the positioning rod is slidably connected to the corresponding slider along the corresponding positioning groove, and the positioning rod is movably connected to a locking piece for fixing the relative position with the slider.

[0007] By adopting the above technical solution, when processing parts of different sizes, the position of the sliding block can be adjusted, and the position of the positioning rod in the positioning groove can also be adjusted to achieve abutment positioning on the inner wall of the workpiece, thereby quickly adapting to workpieces of different sizes for processing.

[0008] Optionally, the locking member includes an abutment member and a first nut, the abutment member is located at the lower end of the positioning rod, the upper end surface of the abutment member abuts against the sliding block below the positioning groove, and the first nut is threadedly connected to the positioning rod above the positioning groove.

[0009] By adopting the above technical solution, the locking member cooperates with the first nut to lock the position of the positioning rod. By adjusting the first nut, the abutment member can abut against the groove wall of the positioning groove to achieve locking of the positioning rod, and the operation is very convenient.

[0010] Optionally, an abutment ring is fixedly provided on the upper end of the positioning rod, and the outer diameter of the abutment ring is larger than the diameter of the circumscribed circle of the first nut.

[0011] By adopting the above technical solution, the abutment ring abuts against the inner wall of the workpiece to achieve a positioning effect. The first nut will not contact the inner wall of the workpiece under the action of the abutment ring, and the positioning accuracy of the workpiece will not be affected by the shape of the first nut.

[0012] Optionally, a avoidance groove is provided at the lower end of the sliding block, the lower end of the positioning groove is communicated with the avoidance groove, and the abutment member is a second nut threadedly connected to the positioning rod.

[0013] By adopting the above technical solution, the length of the positioning rod above the upper end surface of the slider can be adjusted by adjusting the second nut and the first nut, which facilitates positioning of workpieces of different thicknesses and further improves applicability.

[0014] Optionally, the base is provided with several groups of sockets along the arrangement track of the slider, one group of sockets corresponds to one slider, each group of sockets is arranged along the sliding direction of the corresponding slider, a circular hole is provided at the lower end of the slider, a rod is inserted in the circular hole, and the lower end of the rod is adapted to the socket.

[0015] By adopting the above technical solution, the insertion rod can be inserted into the sockets at different positions to achieve multi-level positioning of the base position, which is beneficial to ensure that the length of the slider in different directions is the same each time it is adjusted, thereby ensuring the accuracy after adjustment.

[0016] Optionally, the base is provided with a plurality of strip holes, the strip holes correspond to the sliders one by one, the strip holes are connected to a corresponding group of plug holes, and the width of the strip holes is smaller than the diameter of the plug holes.

[0017] By adopting the above technical solution, under the action of the strip hole, each time the position of the base is adjusted, there is no need to completely remove the insertion rod. The insertion rod can move in the strip hole, which is more convenient and can guide the moving direction of the slider, so that the insertion rod can be quickly inserted into the socket in the adjusted position.

[0018] Optionally, the base is provided with a plurality of strip grooves along the arrangement track of the slider, the strip grooves correspond to the strip holes one by one, the strip grooves and the corresponding strip holes have the same extension direction and are connected to the bottom of the corresponding strip holes, the insertion hole is a threaded hole, and the insertion rod is provided with a threaded portion and a neck from bottom to top, the threaded portion is used to be threadedly connected to the insertion hole, the diameter of the neck is adapted to the width of the strip hole, and the width of the strip groove is greater than or equal to the outer diameter of the threaded portion.

[0019] By adopting the above technical solution, when the user adjusts the position of the slider, the insertion rod can be rotated to disengage the threaded portion from the insertion hole. Under the action of gravity, the insertion rod causes the threaded portion to fall into the strip groove. At the same time, the user moves the slider, and the neck can position the movement of the slider in the strip hole. Finally, the insertion rod is lifted to re-thread the threaded portion into the insertion hole to lock it. Since the threaded portion is below the insertion hole, the insertion rod will not affect the movement of the slider because it falls into the insertion hole every time it passes through the insertion hole. The user does not need to always lift the insertion rod, which makes the operation more convenient.

[0020] Optionally, the insertion rod is provided with a transition section, which is located between the threaded portion and the neck to form a conical transition, and the connection between the insertion hole and the strip groove is conical to match the threaded portion.

[0021] By adopting the above technical solution, the transition section can guide the position of the insertion rod when the user lifts the insertion rod to re-lock the position of the slider, assisting the user to fine-tune the position of the slider, and then quickly aligning the threaded portion with the socket at the corresponding position, thereby improving operational convenience.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When processing parts of different sizes, the position of the sliding block can be adjusted, and the position of the positioning rod in the positioning groove can be adjusted to achieve abutment positioning on the inner wall of the workpiece, so that workpieces of different sizes can be quickly adapted for processing;

[0024] 2. The locking member cooperates with the first nut to lock the position of the positioning rod. By adjusting the first nut, the abutment member can abut against the groove wall of the positioning groove to achieve locking of the positioning rod, which is very convenient to operate;

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] The embodiment of the present application discloses a variable worktable for a gear shaping machine.

[0032] Reference Figure 1 A variable worktable for a gear shaping machine includes a base 1 for connecting to a machine tool. The base 1 can be fixed to the machine tool by bolts or magnets. A plurality of sliders 2 are arranged along a circular track above the base 1. Each slider 2 is slidably connected to the base 1 along the radial direction of the arrangement track. The position of the sliding slider 2 can be adapted to the processing of workpieces of different sizes.

[0033] Reference Figure 1 Specifically, the upper end of the slider 2 is provided with a positioning groove 21, and the positioning groove 21 extends along the sliding direction of the corresponding slider 2. A positioning rod 22 is provided in the positioning groove 21, and the positioning rod 22 is slidably connected to the corresponding slider 2 along the corresponding positioning groove 21. Therefore, the positioning rod 22 can slide relative to the slider 2, and further adjust the positioning position according to the size of the workpiece. The positioning rod 22 is movably connected with a locking member for fixing the relative position with the slider 2, and the position of the positioning rod 22 is fixed by the locking member to ensure stability during processing.

[0034] Reference Figure 1 and Figure 2 The locking member includes an abutment member and a first nut 221. The abutment member is located at the lower end of the positioning rod 22. The upper end surface of the abutment member abuts against the slider 2 at the bottom of the positioning groove 21. The first nut 221 is threadedly connected to the positioning rod 2 at the top of the positioning groove 21. By tightening the first nut 221, the abutment member is pressed against the slider 2, thereby fixing the positioning rod 22.

[0035] Reference Figure 1 and Figure 2 In order to further improve the positioning effect of the workpiece, an abutment ring 223 is fixedly provided at the upper end of the positioning rod 22, and the outer diameter of the abutment ring 223 is larger than the diameter of the circumscribed circle of the first nut 221. The abutment ring 223 is used to abut against the inner wall of the workpiece to achieve positioning. Since the diameter of the abutment ring 223 is larger than the outer diameter of the first nut 221, the first nut 221 will not contact the workpiece, thereby avoiding affecting the positioning accuracy.

[0036] Reference Figure 1 and Figure 2 The lower end of the slider 2 is also provided with an avoidance groove 23, and the lower end of the positioning groove 21 is connected to the avoidance groove 23. The abutment member is a second nut 222 threadedly connected to the positioning rod 22. By adjusting the position of the second nut 222, the length of the positioning rod 22 above the slider 2 can be changed to adapt to workpieces of different thicknesses.

[0037] Reference Figure 2 and Figure 3 In order to facilitate accurate adjustment of the position of the slider 2, the base 1 is provided with a plurality of groups of jacks 11 along the arrangement track of the slider 2, one group of jacks 11 corresponds to one slider 2, and each group of jacks 11 is arranged along the sliding direction of the corresponding slider 2. The base 1 is also provided with a round hole, in which a plug rod 3 is inserted, and the lower end of the plug rod 3 is adapted to the jack 11. When the slider 2 is adjusted to a suitable position, the plug rod 3 can be inserted into the corresponding jack 11 to fix the position of the slider 2.

[0038] Reference Figure 2 and Figure 3 In order to further improve the convenience of adjustment, the base 1 is also provided with a plurality of strip holes 12, which correspond to the sliders 2 one by one. The strip holes 12 are connected to a corresponding group of plug holes 11, and the width of the strip holes 12 is smaller than the diameter of the plug holes 11. In this way, when adjusting the position of the slider 2, the plug rod 3 can be moved in the strip hole 12 without being completely pulled out. This not only plays a guiding role, but also saves adjustment time.

[0039] Reference Figure 2 and Figure 3 In addition, the base 1 is also provided with a plurality of strip grooves 13 along the arrangement track of the slider 2, and the strip grooves 13 correspond to the strip holes 12 one by one. The strip grooves 13 extend in the same direction as the corresponding strip holes 12 and are connected to the bottom of the corresponding strip holes 12. The insertion hole 11 is a threaded hole, and the insertion rod 3 is provided with a threaded portion 31 and a neck 32 from bottom to top. The threaded portion 31 is used to be threadedly connected to the insertion hole 11, the diameter of the neck 32 is adapted to the width of the strip hole 12, and the width of the strip groove 13 is greater than or equal to the outer diameter of the threaded portion 31. This structure allows the slider 2 to be adjusted by simply rotating the insertion rod 3 to disengage the threaded portion 31 from the insertion hole 11, and then moving the slider 2. When the slider 2 moves to the appropriate position, the insertion rod 3 is lifted up to make the threaded portion 31 re-threaded into the insertion hole 11 to lock the position of the slider 2.

[0040] Reference Figure 2 and Figure 3In order to facilitate the alignment and insertion of the insertion rod 3, the insertion rod 3 is also provided with a transition section 33, which is located between the threaded portion 31 and the neck 32 to form a tapered transition. The connection between the insertion hole 11 and the strip groove 13 is also tapered to match the threaded portion 31. In this way, when inserting the insertion rod 3, the transition section 33 can play a guiding role, helping the user to quickly align the threaded portion 31 with the insertion hole 11.

[0041] The working principle of a variable worktable for a gear shaping machine in an embodiment of the present application is as follows: when processing parts of different sizes, the position of the sliding block 2 can be adjusted, and at the same time, the position of the positioning rod 22 in the positioning groove 21 can be adjusted to achieve abutment positioning on the inner wall of the workpiece, thereby quickly adapting to workpieces of different sizes for processing.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
