Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A column clamping device for an automated machine tool, comprising:

[0007] Control panel;

[0008] A clamping assembly is fixed to the top of the control panel and at least one is provided. Each clamping assembly includes two fixed seats fixed to the top of the control panel. Each fixed seat has a mounting opening spaced apart on its top. A rotating rod is rotatably provided through the side wall of the mounting opening via a bearing sleeve. The shafts of the two rotating rods are spaced apart with clamping plates for clamping the column. The front ends of the two rotating rods extend to the rear side of the fixed seat and are provided with two meshing gears.

[0009] A control box is fixedly installed on the top of the control panel, behind the fixed base, and has a gear housed inside. The control box contains a drive assembly for driving a gear to rotate. The drive assembly includes two brackets fixed inside the control box. A spline sleeve is rotatably inserted between the two brackets. A worm gear is fixedly installed on the outer side of the spline sleeve. A drive rod is rotatably inserted through the side wall of the control box via a bearing sleeve. A worm gear that meshes with the worm gear is installed on the shaft of the drive rod.

[0010] The mounting bracket is fixedly installed on the rear side wall of the control box and is in the shape of an inverted "L". A sliding rod is slidably installed through the rear side wall of the mounting bracket. The front end of the sliding rod is rotatably provided with a spline rod that aligns with a spline sleeve and a gear through a bearing seat. The spline rod moves along the central axis of the spline sleeve and the gear, and the spline rod slides through the spline sleeve. The side wall of the gear has a spline groove for the spline rod to slide into / out.

[0011] As a preferred embodiment of the column clamping device for an automated machine tool according to this utility model, the mounting ports on the two fixed seats are staggered front to back, and the clamping plates on the two rotating rods are staggered front to back.

[0012] As a preferred embodiment of the column clamping device for an automated machine tool according to the present invention, the clamping plate is arc-shaped and has anti-slip texture on one side of the concave surface.

[0013] In a preferred embodiment of the column clamping device for an automated machine tool according to this utility model, a geared servo motor is fixedly installed at one end of the drive rod on the top of the control panel, and the output shaft of the geared servo motor is fixedly connected to the end of the drive rod via a coupling.

[0014] In a preferred embodiment of the column clamping device for an automated machine tool according to this utility model, a side plate is fixedly installed at one end of the drive rod on the top of the control panel, and the other end of the drive rod is rotatably connected to the side wall of the side plate through a bearing sleeve.

[0015] In a preferred embodiment of the column clamping device for an automated machine tool according to this utility model, the gap of the spline rod penetrates the rear side wall of the control box, the rod body of the slide rod is fixedly provided with an annular fixing plate, a spring parallel to the slide rod is fixedly provided between the rear side wall of the fixing plate and the side wall of the mounting bracket, the gap of the slide rod penetrates the inner ring of the spring, and a pull ring is provided at the rear end of the slide rod.

[0016] The beneficial effects of this utility model are as follows: The columns that need to be clamped and fixed are placed one by one between two clamping plates. The reduction servo motor is started to drive the drive rod to rotate, which in turn drives the spline rod to rotate via the worm and worm wheel. The spline groove then drives one gear to rotate, while the other gear rotates in the opposite direction, causing the two rotating rods to rotate in opposite directions. This allows all the clamping plates to clamp the columns. For individual columns with different outer diameters, the pull ring can be pulled to slide the sliding rod, allowing the spline rod to be pulled out of the spline groove. At this time, the corresponding two clamping plates can rotate freely independently, thus achieving individual control and clamping of individual columns, which is convenient and practical.

Please refer to [link / reference]. Figures 1-6 This paper provides a detailed description of a column clamping device for an automated machine tool.

[0030] A column clamping device for an automated machine tool includes a control panel 100, a clamping assembly 200, a control box 300, and a mounting frame 400.

[0031] The clamping assembly 200 is fixed to the top of the control panel 100 and at least one is provided. Each clamping assembly 200 includes two fixed seats 201 fixed to the top of the control panel 100. The top of each fixed seat 201 is provided with a mounting opening 202 spaced apart. The side wall of the mounting opening 202 is rotatably provided with a rotating rod 203 through a bearing sleeve. The shafts of the two rotating rods 203 are provided with clamping plates 204 for clamping the column spaced apart. The front ends of the two rotating rods 203 extend to the rear side of the fixed seat 201 and are provided with two meshing gears 205.

[0032] The control box 300 is fixedly installed on the top of the control panel 100, behind the fixed base 201, and its inner cavity houses the gear 205. The control box 300 is equipped with a drive assembly for driving the gear 205 to rotate. The drive assembly includes two brackets 301 fixed inside the control box 300. A spline sleeve 302 is rotatably connected between the two brackets 301. A worm gear 303 is fixedly installed on the outer side of the spline sleeve 302. A drive rod 304 is rotatably connected through the side wall of the control box 300 via a bearing sleeve. The rod body of the drive rod 304 is provided with a worm 305 that meshes with the worm gear 303.

[0033] The mounting bracket 400 is fixedly installed on the rear side wall of the control box 300 and is in the shape of an inverted "L". A slide rod 401 is slidably provided through the rear side wall of the mounting bracket 400. The front end of the slide rod 401 is rotatably provided with a spline rod 402 that aligns with a spline sleeve 302 and a gear 205 via a bearing seat. The spline rod 402 moves along the central axis of the spline sleeve 302 and the gear 205, and the spline rod 402 slides through the spline sleeve 302. The side wall of the gear 205 has a spline groove 403 for the spline rod 402 to slide into / out.

[0034] Wherein: the mounting ports 202 on the two fixed seats 201 are staggered back and forth, and the clamping plates 204 on the bodies of the two rotating rods 203 are staggered back and forth to ensure that the clamping plates 204 will not touch each other when they move.

[0035] Wherein: the clamping plate 204 is arc-shaped, and anti-slip texture is provided on one side of the concave surface to improve anti-slip performance;

[0036] Wherein: A geared servo motor 306 is fixedly installed at one end of the drive rod 304 on the top of the control panel 100. The output shaft of the geared servo motor 306 is fixedly connected to the end of the drive rod 304 through a coupling. A side plate 307 is fixedly installed at one end of the drive rod 304 on the top of the control panel 100. The other end of the drive rod 304 is rotatably connected to the side wall of the side plate 307 through a bearing sleeve. When the geared servo motor 306 is started, it drives the drive rod 304 to rotate, thereby causing all the worm gears 305 to rotate. It should be noted that the number of clamping components 200 is determined by how many worm gears 305 can be driven by the geared servo motor 306 to drive the worm wheel 303 to rotate. Different torque geared servo motors 306 can be customized according to requirements.

[0037] Wherein: the gap of the spline rod 402 penetrates the rear side wall of the control box 300; the rod of the slide rod 401 is fixedly provided with an annular fixing plate 404; a spring 405 parallel to the slide rod 401 is fixedly provided between the rear side wall of the fixing plate 404 and the side wall of the mounting bracket 400; the gap of the slide rod 401 penetrates the coil of the spring 405; and a pull ring 406 is provided at the rear end of the slide rod 401; the spring 405 can push the fixing plate 404 to apply a pushing force to the spline rod 402; when the pull ring 406 is not pulled, the spline rod 402 penetrates the spline sleeve 302 and inserts into the spline groove 403.

[0038] In practical use, the columns that need to be clamped and fixed are placed one by one between the two clamping plates 204. The reduction servo motor 306 is started to drive the drive rod 304 to rotate. Through the worm gear 305 and worm wheel 303, the spline rod 402 is driven to rotate. Then, through the spline groove 403, one gear 205 is driven to rotate, and the other gear 205 rotates in the opposite direction. This causes the two rotating rods 203 to rotate in opposite directions, which can drive all the clamping plates 204 to clamp the columns. For individual columns with different outer diameters, the pull ring 406 can be pulled to drive the slide rod 401 to slide, so that the spline rod 402 is pulled out of the spline groove 403. At this time, the corresponding two clamping plates 204 can rotate freely, thereby realizing individual control and clamping of individual columns, which is convenient and practical.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
