[0019] The method for using the above tool processing passivation treatment device comprises the following steps:

[0020] Step 1: First, open the door and install the milling cutters to be passivated in each clamping head one by one, making sure that each milling cutter is firmly clamped;

[0021] Step 2: Then, close the opening and closing door, start the lifting cylinder, and the lifting cylinder drives the lifting plate and the auxiliary mechanism at the bottom to move downward until the milling cutter is completely inserted into the abrasive storage cylinder;

[0022] Step 3: Then, the rotating motor is started, and the output end of the rotating motor drives the first conical gear and the turntable to rotate back and forth in forward and reverse directions through the rotating shaft. The turntable drives the clamped milling cutter to rotate through the reciprocating rod, the connecting plate, and the side plate, thereby realizing the rotation grinding function of the milling cutter;

[0023] Step 4: While rotating and grinding, the first conical tooth drives the second conical tooth and the screw to rotate.

[0026] Beneficial effects of the present invention:

[0027] 1. The present invention drives the first conical tooth and the rotating disk to move back and forth in a forward and reverse direction by rotating the motor. When the rotating disk moves back and forth in a forward and reverse direction, the clamping head can be driven to rotate forward and reversely through the reciprocating rod, the side plate, the connecting plate, etc., and then the milling cutter clamped by the clamping head is driven to rotate, thereby realizing the rotation grinding function of the milling cutter. At the same time, when the first conical tooth rotates forward and reversely, the second conical tooth meshingly connected therewith can drive the screw rod to rotate forward and reversely. When the screw rod rotates forward and reversely, the reciprocating rod can move back and forth, and the reciprocating rod drives the milling cutter to move back and forth through the connecting plate, thereby realizing the reciprocating grinding operation of the milling cutter. When the reciprocating rod moves back and forth, the first gear, the second gear, the rack, etc. can be used in combination to drive the clamping head to drive the clamped milling cutter to swing back and forth, thereby realizing the swing grinding of the milling cutter. Therefore, the present invention not only realizes the rotation grinding of the milling cutter, but also combines rotation with reciprocating movement and swinging, thereby realizing the all-round grinding of the milling cutter, and it is not easy to have a passivation dead angle, thereby improving the comprehensiveness and quality of passivation.

[0028] 2. In the present invention, by using the first gear, the second gear, the rack, etc. in coordination, the moving direction of the milling cutter can always be opposite to the swinging direction of the milling cutter, so that one side is subjected to a passivation force during movement, while the other side is subjected to a force in the opposite direction during swinging, which helps to distribute the passivation force more evenly on various parts of the milling cutter, thereby improving the passivation effect and the overall performance of the tool.

[0045] Example 1

[0046] Reference Figure 1-8 , which is the first embodiment of the present invention, provides a tool processing passivation treatment device, which mainly includes:

[0047] The main unit 100, such as Figure 2The main unit 100 includes a chassis 101 and positioning plates 102 respectively fixed to the inner walls of the left and right sides of the chassis 101. By setting the positioning plates 102, the abrasive storage cylinder 201 can be quickly positioned and installed. The bottom and front side of the chassis 101 are both open structures, which are convenient for pushing the abrasive storage cylinder 201 into the chassis 101. The front side of the chassis 101 is hinged with an opening and closing door 103, and a transparent observation window 104 is installed on the opening and closing door 103. By setting the transparent observation window 104, it is convenient to observe the passivation situation inside the chassis 101.

[0048] An abrasive storage unit 200 , which is disposed at the bottom of the chassis 101 and fixedly connected to the positioning plate 102 ;

[0049] like Figure 3 The abrasive storage unit 200 includes an abrasive storage cylinder 201, in which abrasives are stored. The bottom of the abrasive storage cylinder 201 is fixedly connected with supporting legs 202 in a rectangular array, and a universal wheel 203 is fixedly installed at the bottom of the supporting legs 202 for easy movement. The left and right sides of the abrasive storage cylinder 201 are fixedly connected with fixing plates 204, and the rear side of the fixing plate 204 is movably fitted with the positioning plate 102. A positioning bolt 205 is movably connected to the fixing plate 204, and the head end of the positioning bolt 205 is threadedly connected to the positioning plate 102, which is used to fix the abrasive storage cylinder 201 so that it corresponds to the first passivation treatment unit 300 and the second passivation treatment unit 400 up and down.

[0050] The first passivation treatment unit 300 is fixedly connected to the top of the chassis 101 and is used for rotating and lifting the milling cutter.

[0051] The second passivation treatment unit 400 is installed in a ring array at the bottom of the first passivation treatment unit 300 and is used to reciprocate the milling cutter.

[0052] Specifically, Figure 6 The first passivation treatment unit 300 includes a pair of lifting cylinders 301 fixedly connected to the top of the chassis 101 by bolts, the piston ends of the pair of lifting cylinders 301 are movably inserted into the chassis 101 and fixedly connected to the same lifting plate 302 by bolts, a rotating motor 303 is fixedly installed at the bottom center of the lifting plate 302 by bolts, the bottom output end of the rotating motor 303 is fixedly connected to a rotating shaft, the bottom end of the rotating shaft is fixedly connected to a first conical tooth 304, the outside of the rotating shaft is fixedly sleeved above the first conical tooth 304, and a turntable 305 is fixedly sleeved on the outside of the rotating shaft above the first conical tooth 304, and a plurality of guide grooves 306 are opened in a ring array at the bottom of the turntable 305. The number of the second passivation treatment unit 400 is consistent with that of the guide grooves 306, and they correspond one to one.

[0053] When the milling cutter is rotationally ground, the rotating motor 303 is started, and the output end of the rotating motor 303 drives the first conical tooth 304 and the turntable 305 to rotate back and forth in forward and reverse directions through the rotating shaft. The turntable 305 drives the clamped milling cutter to rotate through the second passivation treatment unit 400, thereby realizing the rotational grinding function of the milling cutter.

[0054] Specifically, Figure 7 The second passivation treatment unit 400 includes a reciprocating rod 401 adapted to slide with the guide groove 306 and a connecting disk 402 fixedly connected to the bottom end of the reciprocating rod 401. A screw rod 403 is spirally penetrated on the reciprocating rod 401, and a second conical tooth 404 is fixedly connected to one end of the screw rod 403. The top of the second conical tooth 404 is meshed with the bottom of the first conical tooth 304. A pair of side plates 405 are rotatably sleeved on the screw rod 403. The pair of side plates 405 are respectively arranged at both ends of the guide groove 306, and the tops of the side plates 405 are fixedly connected to the bottom of the turntable 305. By setting a pair of side plates 405, the screw rod 403 is fixed so that it can rotate stably.

[0055] Four grooves 406 are evenly arranged at the edge of the connecting disk 402, and a swing rod 407 is movably arranged in the groove 406. A notch is arranged at the top of the swing rod 407, and a second connecting shaft 410 is fixedly passed through the notch. A mounting plate 411 is rotatably mounted on one end of the second connecting shaft 410 through a bearing, and the bottom of the mounting plate 411 is fixedly connected to the upper surface of the connecting disk 402. The mounting plate 411 is provided to fix the swing rod 407 so that it can swing smoothly. A clamping head 408 is fixedly connected to the bottom end of the swing rod 407, and the clamping head 408 is used to clamp the milling cutter. The outside of the second connecting shaft 410 is fixedly sleeved with a first gear 409 in the notch, and the first gear 409 is connected to the swing drive unit 500.

[0056] Furthermore, Figure 6 The swinging plane of the swinging rod 407 is parallel to the moving plane of the reciprocating rod 401. The purpose of this arrangement is to limit the installation of the first gear 409 so that when the first gear 409 rotates, the swinging plane of the swinging rod 407 can be parallel to the moving plane of the reciprocating rod 401.

[0057] In summary, when in use, the lifting cylinder 301 is started, and the lifting cylinder 301 drives the lifting plate 302 and the auxiliary mechanism at the bottom thereof to move downward until the milling cutter is completely inserted into the abrasive storage tube 201. Then, the rotating motor 303 is started, and the output end of the rotating motor 303 drives the first conical teeth 304 and the turntable 305 to rotate back and forth through the rotating shaft, and the turntable 305 drives the clamped milling cutter to rotate through the reciprocating rod 401, the connecting plate 402, and the side plate 405, thereby realizing the rotation grinding function of the milling cutter. While rotating and grinding, the first conical teeth 304 drive the second conical teeth 404 and the screw rod 403 to rotate, and when the screw rod 403 rotates, the reciprocating rod 401 reciprocates along the screw rod 403 under the guiding action of the guide slot 306, and the reciprocating rod 401 drives the clamped milling cutter to move back and forth through the connecting plate 402, thereby realizing the reciprocating grinding operation of the milling cutter.

[0058] Example 2

[0059] Reference Figure 9-10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the device also includes a swing drive unit 500, which is connected to the second passivation treatment unit 400 and is used to swing the milling cutter, and the back-and-forth swinging direction is opposite to the reciprocating movement direction of the milling cutter.

[0060] Specifically, the swing drive unit 500 includes an annular plate 501 fixedly connected to the bottom end of a pair of side plates 405 and four second gears 502 located below the annular plate 501. The four second gears 502 are respectively meshed with the tops of four first gears 409. The tops of the four second gears 502 are all meshed with racks 503, and the racks 503 are arranged parallel to the moving direction of the reciprocating rod 401. The top of the rack 503 is fixedly connected to the bottom of the annular plate 501. A first connecting shaft is fixedly passed through the center of the second gear 502. The same U-shaped frame 504 is rotatably installed at the front and rear ends of the first connecting shaft. A fixing rod 505 is fixedly connected to one side of the U-shaped frame 504, and the bottom end of the fixing rod 505 is fixedly connected to the top of the connecting plate 402.

[0061] The remaining structures are the same as those of Example 1.

[0062] When in use, on the basis of rotation and reciprocating movement, through the fixing effect of the U-shaped frame 504 and the fixing rod 505 and the connecting plate 402, the second gear 502 follows the movement, and due to the meshing effect of the second gear 502 and the rack 503, the second gear 502 rotates accordingly, and the second gear 502 drives the first gear 409 meshed with it to rotate, and the first gear 409 drives the swing rod 407 to swing through the second connecting shaft 410, thereby realizing the swing grinding of the milling cutter, and the moving direction of the milling cutter is always opposite to the swing direction of the milling cutter. This composite motion can avoid excessive wear of the milling cutter. In the process of milling cutter passivation, if some parts wear too fast, the shape accuracy of the milling cutter will decrease, affecting the passivation effect. The design of moving in the opposite direction of the swing direction makes the wear speed of each part of the milling cutter relatively balanced. Because each part has the opportunity to contact with the abrasive under different motion states and bear different degrees of passivation force, a more uniform distribution of the passivation force on each part of the milling cutter is achieved, ensuring the consistency of the passivation quality and overall performance of the milling cutter.

[0063] The method of using the above tool processing passivation treatment device is as follows: first, open the opening and closing door 103, install the milling cutters to be passivated in each clamping head 408 one by one, and ensure that each milling cutter is firmly clamped; then, close the opening and closing door 103, start the lifting cylinder 301, and the lifting cylinder 301 drives the lifting plate 302 and the auxiliary mechanism at the bottom to move downward until the milling cutter is completely inserted into the abrasive storage cylinder 201; then, start the rotating motor 303, and the output end of the rotating motor 303 drives the first cone through the rotating shaft. The teeth 304 and the rotating disk 305 rotate back and forth in a positive and negative direction, and the rotating disk 305 drives the clamped milling cutter to rotate through the reciprocating rod 401, the connecting disk 402, and the side plate 405, thereby realizing the rotation grinding function of the milling cutter; while rotating and grinding, the first conical teeth 304 drive the second conical teeth 404 and the screw rod 403 to rotate. When the screw rod 403 rotates, the reciprocating rod 401 reciprocates along the screw rod 403 under the guidance of the guide slot 306. The reciprocating rod 401 drives the connecting disk 402 to drive the screw rod 403 to rotate. The milling cutter clamped by the motor moves back and forth, thereby realizing the reciprocating grinding operation of the milling cutter; on the basis of the reciprocating movement, the second gear 502 follows the movement through the fixing effect of the U-shaped frame 504 and the fixing rod 505 and the connecting plate 402, and due to the meshing effect of the second gear 502 and the rack 503, the second gear 502 rotates accordingly, and the second gear 502 drives the first gear 409 meshing with it to rotate, and the first gear 409 drives the swing rod 407 to swing through the second connecting shaft 410, thereby realizing the milling The swing grinding of the cutter, and the moving direction of the milling cutter is always opposite to the swing direction of the milling cutter, which helps to distribute the passivation force more evenly on various parts of the milling cutter; when the passivation treatment reaches the predetermined time or effect, the operation of the rotating motor 303 is stopped, and then the lifting cylinder 301 drives the lifting plate 302 to move upward, and the passivated milling cutter is pulled out of the abrasive storage tube 201, and then the opening and closing door 103 is opened, and the milling cutters are disassembled one by one, and then the work area and equipment are cleaned up to prepare for the next use, and the passivation treatment is completed.

[0064] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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, which should all be included in the scope of the claims of the present invention.
