The indexing plate, as one of the key components of a machining center, functions to achieve precise positioning and rotation of the workpiece during machining, thereby improving machining accuracy and efficiency.

[0003] However, in practical applications, there is a common problem when tailstocks are used in conjunction with indexing plates: traditional tailstock designs can often only fix fixtures of a specific size, which means that when dealing with workpieces of different specifications or shapes, it is necessary to replace the tailstock or readjust the fixture, which increases the difficulty of operation and reduces production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a tailstock that works with the indexing plate of a machining center, aiming to solve the technical problem that existing traditional tailstock designs can only fix fixtures of specific sizes.

The tailstock is located on the right side of the indexing plate, and the indexing plate and the tailstock are provided with limiting components that can limit and fix different clamping assemblies.

[0006] The limiting assembly includes a limiting plate, a limiting bolt, a limiting hole, and a fixing bolt. The limiting plate is disposed on the indexing plate and the positioning bolt. The limiting bolt is disposed on the opposite side of the limiting plate, and its other end passes through and is connected to the positioning bolt. The limiting hole is opened on the limiting plate, and its two ends pass through to its top and bottom. The fixing bolt is threadedly connected to the limiting hole.

[0007] Optionally, the number of limiting holes is multiple, and there is a gap between the multiple limiting holes.

[0008] Optionally, the tailstock includes a fixed plate, a limiting groove, a positioning groove, a positioning bolt, a sealing ring, a bearing, a nut, a protective cover, and a limiting assembly. The limiting groove is formed on the fixed plate, the positioning groove is formed on the fixed plate and its other end is connected to the limiting groove, the positioning bolt is disposed on the limiting groove, the sealing ring is sleeved on the positioning bolt, the bearing is disposed on the positioning groove and sleeved on the positioning bolt, the nut is sleeved on the positioning bolt, the protective cover is disposed on the fixed plate, and the limiting assembly is disposed on the positioning bolt.

[0009] Optionally, the fixing plate and the protective cover are provided with threaded holes, and a bolt is provided in the threaded holes.

[0010] Optionally, the fixture assembly includes a fixture frame and a positioning hole, the fixture frame is mounted on the limiting plate, and the positioning hole is formed on the fixture frame.

[0011] Optionally, the number of positioning holes is multiple, and a spacing is provided between the multiple positioning holes, the spacing between the multiple positioning holes being equal to the spacing between the multiple limiting holes.

[0012] The technical solution of this utility model has the following beneficial effects: When it is necessary to limit and fix a fixture frame with different widths or thicknesses at the front and rear, the fixture frame is first placed on the center of the limiting plate, and the center of the positioning hole is aligned with the center of the limiting hole. Then, the fixing bolt is screwed down from the top of the positioning hole to the inside of the limiting hole to limit and fix the fixture frame. When the bottom thickness of the fixture frame is greater than the length of the fixing bolt, the fixing bolt is screwed up from the bottom of the limiting hole to the inside of the positioning hole, thereby completing the limit and fixation of fixture frames of different sizes.

[0023] This utility model proposes a tailstock that works in conjunction with the indexing plate of a machining center.

[0024] like Figures 1 to 4 As shown, in one embodiment of the present invention, the tailstock of the indexing plate of the machining center includes an indexing plate 1, a clamping assembly 4 and a positioning bolt 24. The indexing plate 1 facilitates the rotation and adjustment of the clamping assembly 4. A tailstock 2 is provided on the right side of the indexing plate 1. A limiting assembly 3 is provided on the indexing plate 1 and the tailstock 2 to limit and fix different clamping assemblies 4.

[0025] The limiting assembly 3 includes a limiting plate 31, a limiting bolt 32, a limiting hole 33, and a fixing bolt 34. The limiting plate 31 is disposed on the indexing plate 1 and the positioning bolt 24. The limiting bolt 32 is disposed on the opposite side of the limiting plate 31, and its other end passes through and is connected to the positioning bolt 24. The limiting bolt 32 and the limiting hole 33 are opened on the limiting plate 31, and both ends pass through to its top and bottom. The fixing bolt 34 is threadedly connected to the limiting hole 33.

[0026] Specifically, there are multiple limiting holes 33, and there are intervals between the multiple limiting holes 33. The limiting holes 33 can be easily adapted to clamp assemblies 4 of different sizes through limiting bolts 32.

[0027] Specifically, the tailstock 2 includes a fixed plate 21, a limiting groove 22, a positioning groove 23, a positioning bolt 24, a sealing ring 25, a bearing 26, a nut 27, a protective cover 28, and a limiting assembly 3. The limiting groove 22 is formed on the fixed plate 21, and the limiting groove 22 facilitates the limiting of the sealing ring 25. The positioning groove 23 is formed on the fixed plate 21, and its other end is connected to the limiting groove 22. The positioning groove 23 facilitates the limiting of the bearing 26. The positioning bolt 24 is located on the limiting groove 22, and the sealing ring 25... The sealing ring 25 is fitted onto the positioning bolt 24 to prevent lubricating oil from dripping from the bearing 26.

[0030] Specifically, there are multiple positioning holes 42, and there is a spacing between the multiple positioning holes 42. The spacing between the multiple positioning holes 42 is equal to the spacing between the multiple limiting holes 33, so that the fixing bolts 34 can pass through the positioning holes 42 and the limiting holes 33 for threaded connection, thereby limiting and fixing the fixture frame 41. When the base plate of the fixture frame 41 is relatively thick, the fixing bolts 34 can be installed from the top of the limiting holes 33 upwards, passing through the limiting holes 33 and the positioning holes 42 for threaded connection, thereby limiting and fixing the fixture frame 41.

[0031] Specifically, the working principle and usage process of this utility model are as follows:

[0032] When it is necessary to limit and fix the fixture frame 41 with different widths or thicknesses at the front and back, first place it on the center of the limiting plate 31, align the center of the positioning hole 42 with the center of the limiting hole 33, and then screw the fixing bolt 34 from the top of the positioning hole 42 downward into the inside of the limiting hole 33 to limit and fix the fixture frame 41. When the bottom thickness of the fixture frame 41 is greater than the length of the fixing bolt 34, screw the fixing bolt 34 from the bottom of the limiting hole 33 upward into the inside of the positioning hole 42, thereby completing the limit and fixation of the fixture frame 41 of different sizes.
