[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-11 , which is the first embodiment of the utility model, provides a multi-angle fixed vertical mill CNC lathe with a shock-absorbing base. The multi-angle fixed vertical mill CNC lathe with a shock-absorbing base includes a main body component 100, including a workbench 101 and a turntable 102, and the turntable 102 is arranged on the workbench 101.

[0036] The uniform rotation of the turntable 102 allows the grinding head to evenly grind the surface of the workpiece, avoiding local over- or under-machining and improving machining accuracy.

[0037] The clamping assembly 200 includes a clamping member 201, which is located on the turntable 102, including a support plate 201a, a sleeve 201b, a first movable column 201c, a clamping plate 201d, a fixed plate 201e and a spiral column 201f. The support plate 201a is fixed on the workbench 101, the sleeve 201b is inserted into the support plate 201a, the first movable column 201c is inserted into the sleeve 201b, the clamping plate 201d is fixed to one end of the first movable column 201c, the fixed plate 201e is fixed to one side of the clamping plate 201d, and the spiral column 201f is inserted into the fixed plate 201e.

[0038] The clamping member 201 is used to fix the workpiece to prevent the workpiece from shifting during the processing. The sleeve 201b is connected to the support plate 201a bearing. A fourth spring 201h is fixed to one side of the first movable column 201c. The other end of the fourth spring 201h is fixed to the inner wall of the sleeve 201b and is used to connect the sleeve 201b and the first movable column 201c. A spiral groove corresponding to the spiral column 201f is opened in the fixed plate 201e. Through the cooperation between the spiral groove and the spiral column 201f, when the spiral column 201f rotates, it drives the fixed plate 201e to move.

[0039] The clamping assembly 200 further includes a flip member 202, which is disposed on the turntable 102 and includes a secondary clamping plate 202a, a second movable column 202b, a rotating sleeve 202c, a clamping block 202d, a movable block 202e, an arc-shaped plate 202f, and a first spring 202g. The clamping plate 201d is provided with a sliding groove 201d-1, the secondary clamping plate 202a slides in the sliding groove 201d-1, the second movable column 202b is fixed to one end of the secondary clamping plate 202a, the rotating sleeve 202c is connected to the sleeve 201b bearing, and the rotating sleeve 20 2c is sleeved on the outside of the second movable column 202b, and a thread groove 202b-1 is opened at one end of the second movable column 202b. The blocking block 202d is fixed on the rotating sleeve 202c and slides in the thread groove 202b-1. One end of the movable block 202e is fixed to the second movable column 202b, and the movable block 202e is opened with a movable groove 202e-1. One end of the arc plate 202f slides in the movable groove 202e-1. The two ends of the first spring 202g are respectively fixed to the movable groove 202e-1 and the arc plate 202f.

[0040] The flipping member 202 is used to flip the fixture to drive the workpiece to flip, thereby avoiding secondary clamping and improving production efficiency. The rotating sleeve 202c is connected to the sleeve 201b bearing. Through the cooperation of the clamping block 202d and the threaded groove 202b-1, when the rotating sleeve 202c rotates, it drives the clamping block 202d to slide in the threaded groove 202b-1, thereby moving the second movable column 202b, and thus moving the auxiliary clamping plate 202a. When the auxiliary clamping plate 202a fits tightly against the workpiece, the workpiece will be stably fixed in the fixture, and when the auxiliary clamping plate 202a is not tightly fitted, the workpiece will move slowly under its own gravity.

[0041] The curved plate 202f assists in clamping the workpiece, and the first spring 202g applies continuous thrust to the curved plate 202f, while connecting the curved plate 202f and the moving block 202e. When the workpiece is placed between the clamping plate 201d and the auxiliary clamping plate 202a, the bottom of the workpiece will contact the curved plate 202f, thereby assisting in clamping the workpiece. When the rotating sleeve 202c rotates and drives the second moving column 202b away from the workpiece, the second moving column 202b will drive the moving block 202e to move, thereby moving the curved plate 202f away from the workpiece. At this time, the workpiece will slowly move forward under its own gravity. At this time, when the rotating sleeve 202c rotates in the opposite direction to drive the second moving column 202b close to the workpiece, the moving block 202e moves accordingly, and the first spring 202g will be compressed. The curved plate 202f slides in the moving groove 202e-1 and will not hinder the auxiliary clamping plate 202a from approaching the workpiece.

[0042] Example 2

[0043] Reference Figures 1-11 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0044] Specifically, a limiting groove 201c-1 is defined in the first movable column 201c, a limiting block 201g is fixed in the sleeve 201b, and the limiting block 201g slides in the limiting groove 201c-1.

[0045] By setting the limiting block 201g and the limiting groove 201c-1, it is ensured that the rotation of the sleeve 201b can drive the first movable column 201c to rotate at the same time, and the distance between the two can be changed to facilitate clamping.

[0046] Specifically, an arc-shaped block 202h is fixed on the turntable 102 .

[0047] When the arc plate 202f is away from the workpiece and the workpiece slowly moves downward under the action of gravity, the bottom edge of the workpiece will contact the arc edge of the arc block 202h. The arc setting avoids obstruction to the subsequent flipping of the fixture.

[0048] Specifically, the clamping assembly 200 also includes a locking member 203, located on one side of the clamping plate 201d, including a first handle 203a, a first round block 203b, a first locking block 203c and a second spring 203d. The first handle 203a is fixed on the sleeve 201b, the first round block 203b is fixed to the first handle 203a, the support plate 201a is provided with a first locking groove 201a-1, the first locking block 203c slides in the first locking groove 201a-1, and the two ends of the second spring 203d are fixed to the first locking block 203c and the first locking groove 201a-1.

[0049] The locking member 203 is similar to the locking clamping member 201 and the flipping member 202 , and prevents the workpiece from shifting during the processing, thereby affecting the production efficiency.

[0050] An arc-shaped sliding groove corresponding to the first round block 203b is provided in the support plate 201a, and the second spring 203d applies a continuous thrust to the first locking block 203c to ensure that the first locking block 203c can move to the side of the first round block 203b. One end of the first locking block 203c is inclined. Through the inclined setting, when the first round block 203b is located on the side of the right-angled surface of the first locking block 203c, the first locking block 203c hinders the movement of the first round block 203b, thereby locking the position of the sleeve 201b. When the first round block 203b is located on the side of the inclined surface of the first locking block 203c, the first round block 203b will squeeze the inclined surface, and the second spring 203d will be compressed, so that the first round block 203b can move, and the sleeve 201b can rotate at this time.

[0051] A first pull rope 203i is fixed to one end of the first locking block 203c. Pulling the first pull rope 203i compresses the second spring 203d, thereby unlocking the sleeve 201b.

[0052] Specifically, the locking member 203 also includes a second handle 203e, a second round block 203f, a second locking block 203g and a third spring 203h. The second handle 203e is fixed to the rotating sleeve 202c, the second round block 203f is fixed to one side of the second handle 203e, the sleeve 201b is provided with a second locking groove 201b-1, the second locking block 203g slides in the second locking groove 201b-1, and the third spring 203h is fixed to one side of the second locking block 203g.

[0053] An arc-shaped groove corresponding to the second round block 203f is provided in the sleeve 201b, and the second round block 203f slides in the arc-shaped groove. The third spring 203h applies a continuous thrust to the second locking block 203g. One end of the second locking block 203g is inclined. When the second round block 203f is located on one side of the right-angled surface of the second locking block 203g, the second locking block 203g will hinder the movement of the second round block 203f, thereby limiting the rotation of the rotating sleeve 202c. When the second round block 203f is located on one side of the inclined surface of the second locking block 203g, the second round block 203f presses the inclined surface, and the third spring 203h is compressed. At this time, the rotating sleeve 202c can rotate.

[0054] A second pull rope 203j is fixed to one side of the second locking block 203g. Pulling the second pull rope 203j compresses the third spring 203h, thereby unlocking the rotating sleeve 202c and allowing the rotating sleeve 202c to rotate again.

[0055] Specifically, the thread directions of the two ends of the spiral column 201f are opposite.

[0056] By setting in reverse, when the spiral column 201f rotates, the fixing plates 201e at both ends move simultaneously, thereby making the fixing plates 201e move closer to or farther away from each other.

[0057] Example 3

[0058] Reference Figures 1-11 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0059] Specifically, one end of the first locking block 203c and the second locking block 203g are both triangular.

[0060] Specifically, there are two groups of clamping members 201 .

[0061] The clamping member 201 clamps the workpiece synchronously from two directions.

[0062] Specifically, there are two first locking blocks 203c and two second springs 203d, and they correspond one to one.

[0063] By setting two sets of first locking blocks 203c and second springs 203d, the position of the sleeve 201b can be locked in two positions. The angle between the two sets is 180 degrees, and the two positions correspond to the forward clamping and the flipped clamping of the clamping member 201, thereby locking the position of the clamping member 201.

[0064] Specifically, the main assembly 100 further includes a base 103 , a control mechanism 104 and a grinding mechanism 105 . The base 103 is fixed to the bottom of the workbench 101 , the control mechanism 104 is located above the workbench 101 , and the grinding mechanism 105 is fixed to one side of the control mechanism 104 .

[0065] The base 103 is used to support the entire machine tool. A vibration reduction mechanism is provided in the base 103, which can effectively reduce the vibration generated by the processing, making the grinder more stable during the processing, thereby improving the processing accuracy. The control mechanism 104 is used to control the motion trajectory and speed of each component of the grinder, and the grinding mechanism 105 is used to grind the workpiece. This is the existing technology, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0066] When in use, the workpiece is placed between the two clamping plates 201d, and the rotating spiral column 201f drives the two fixed plates 201e to move closer to the workpiece, thereby driving the clamping plates 201d on both sides to clamp the workpiece and make the bottom of the workpiece contact with the curved plate 202f. Then, the second handle 203e is rotated to drive the second round block 203f to move to one side of the right-angled side of the second locking block 203g, limiting the rotation of the rotating sleeve 202c. At the same time, the second handle 203e drives the rotating sleeve 202c to rotate, and drives the clamping block 202d to slide in the threaded groove 202b-1, thereby moving the second movable column 202b, driving the auxiliary clamping plate 202a to move toward the workpiece, so that the workpiece is stably fixed between the auxiliary clamping plate 202a and the clamping plate 201d.

[0067] When the second round block 203f moves to one side of the right-angled surface of the second locking block 203g, the rotating sleeve 202c is locked again to limit the rotation.

[0068] Pull the first pull rope 203i to compress the second spring 203d, unlock the sleeve 201b, and then rotate the first handle 203a to drive the sleeve 201b to rotate, thereby driving the first movable column 201c to rotate, and then driving the splint 201d to flip, realizing the flipping of the workpiece. At the same time, rotate the first handle 203a to move the first round block 203b to the side of the right-angle surface of the first locking block 203c, and lock the position of the sleeve 201b again to prevent its rotation from affecting the processing.

[0069] After the processing is completed, the rotating spiral column 201f drives the two fixed plates 201e away from the workpiece, and the workpiece can be removed. When clamping again, it is necessary to ensure that the arc plate 202f is located below the clamping plate 201d.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
