[0040] Embodiment 1

[0041] Reference Figure 1-10 , which is an embodiment of the present invention, provides a precision polishing device for manufacturing numerical control tools, including: a tool polishing unit 100, an automatic unloading unit 200, and a unloading pushing unit 300.

[0042] Among them, the tool polishing unit 100 includes a base 101 and a turntable 103 rotatably installed on the base for placing a plurality of evenly distributed numerical control tools 104. The stepping motor 102 is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates by an angle or advances one step. In the present invention, each time the trigger switch 211-1 is squeezed, it will control the stepping motor 102 to rotate a certain angle. Moreover, a circular groove matching the stepping motor 102 is provided on the base 101. The output shaft of the stepping motor 102 is fixedly connected to a turntable 103 matching the circular groove. A support ring 108 is fixedly installed on the inner wall of the circular groove. The lower side wall edge of the turntable 103 abuts against the upper side wall of the support ring 108. The setting of the support ring 108 can assist in supporting the turntable 103 during rotation and can effectively share the pressure borne by the output shaft of the stepping motor 102;

[0043] Furthermore, a sealing ring 109 is also fixedly installed at the upper end of the side wall of the turntable 103. The setting of the sealing ring 109 can block the gap between the circular groove and the turntable 103, effectively solving the defect that sandblasting particles are likely to fall into the circular groove through the gap between the two during the sandblasting and polishing process, which brings inconvenience to subsequent cleaning. Multiple groups of evenly distributed numerical control tools 104 are provided at the upper edge of the turntable 103. And a polishing box 105 is fixedly installed at one end of the upper side wall of the base 101. In practical applications, the polishing box 105 generally also includes a robotic arm and a polishing spray gun. The polishing box 105, the robotic arm, and the polishing spray gun are all inherent components of the polishing device and are often used in the field of sandblasting and polishing the tips of numerical control tools 104. Here, their specific structures and working principles will not be introduced in detail. And a strip-shaped opening matching the numerical control tool 104 is provided on the side wall of the polishing box 105. A storage box 107 is placed at one end of the base 101. And a guiding cover 107a is provided on the storage box 107. And the storage box 107 is arranged close to the second pressing block 213-1. The storage box 107 can store the polished numerical control tools 104;

[0044] Secondly, the automatic unloading unit 200 includes a plurality of mounting seats 201 rotatably arranged on the upper side wall of the turntable 103 and sockets 202 inserted into each mounting seat 201 in a matching manner. A long skirt edge 202a and a short skirt edge 202b are respectively fixedly connected to the lower end of each socket 202. The long skirt edge 202a is arranged close to the edge of the turntable 103, and the short skirt edge 202b is arranged away from the long skirt edge 202a. Combining Figure 8, when the eccentric ejector rod 210-1 jacks upward, the short skirt edge 202b first disengages from the mounting base 201. When the eccentric ejector rod 210-1 continues to jack upward, at this time, with the long skirt edge 202a limited by the pressing cover 302, it can knock down the socket 202 and the numerical control tool 104 and send them into the guiding cover 107a, so as to ensure that while the numerical control tool 104 is automatically unloaded, it can be arranged at the same time. Each numerical control tool 104 is inserted on the corresponding socket 202. A through hole is vertically provided through each mounting base 201, and the through hole penetrates downward through the turntable 103. A driving motor 203 is vertically slidably connected in the turntable 103. The lower end of the driving motor 203 is fixedly connected with a sliding sleeve 205 through a lower connecting rod 204. A corresponding return spring 206 is sleeved on each lower connecting rod 204, and the return spring 206 is located between the upper side wall of the sliding sleeve 205 and the lower side wall of the turntable 103. Through the setting of the return spring 206, it can assist the upper connecting rod 208 and the lower connecting rod 204 to reset in the through hole;

[0045] Furthermore, in combination with Figure 5 As shown, when the upper connecting rod 208-1 jacks upward to the highest end along the through hole, the return spring 206 with the largest extrusion amount can assist the eccentric ejector rod 210-1 and the upper connecting rod 208-1 to reset downward. An inclined sliding ring 207 corresponding to multiple groups of sliding sleeves 205 is fixedly provided on the base 101. The automatic unloading unit 200 further includes a unloading trigger component 208 for controlling the jacking and unloading of the numerical control tool 104;

[0046] The unloading trigger component 208 includes an upper connecting rod 208-1 fixedly arranged at the upper end of the output shaft of the driving motor 203, and the upper connecting rod 208-1 penetrates upward through the through hole and is fixedly connected with an eccentric ejector rod 210-1. The upper connecting rod 208-1 is vertically slidably connected with the mounting base 201. Multiple groups of evenly distributed trigger switches 211-1 are inlaid and installed on the side wall of the turntable 103, and a first extrusion block 212-1 and a second extrusion block 213-1 are symmetrically arranged in the circular groove. The trigger switch 211-1 is electrically connected with the stepping motor 102 and the driving motor 203;

[0047] In combination with Figure 7 As shown, the inclined sliding ring 207 includes a feeding part 207a, a polishing part 207b, a discharging part 207c and a unloading part 207d. The feeding part 207a, the polishing part 207b, the discharging part 207c and the unloading part 207d are arranged in a clockwise order in sequence, and the polishing part 207b is located in the polishing box 105. The unloading part 207d is close to the storage box 107. By using the change in the height of the inclined sliding ring 207, the sliding sleeve 205 sleeved on it is controlled to change at different heights at different positions, so as to complete the feeding, polishing, discharging and unloading processes of the numerical control tool 104, and indirectly reduce the manual participation degree in the polishing process of the numerical control tool 104.

[0048] Next, the unloading pushing unit 300 includes a plurality of support arms 301 fixedly installed on the upper side wall of the turntable 103 and a pressing cover 302 fixedly installed on the support arms 301, and the pressing cover 302 abuts against the numerical control tool 104. When the eccentric ejector rod 210-1 jacks up upward, the setting of the pressing cover 302 can ensure that the eccentric ejector rod 210-1 tilts towards the storage box 107, facilitating the subsequent sorting and arranging of the numerical control tool 104.

[0049] A method for using a precision polishing device for manufacturing numerical control tools includes the following steps:

[0050] S1: Insert the numerical control tools 104 that need to be precision polished into the corresponding sockets 202 in sequence, and control the turntable 103 to rotate through the stepping motor 102, and send the numerical control tools 104 into the polishing box 105 in sequence;

[0051] S2: When directly above the polishing part 207a of one of the numerical control tools 104, the corresponding first pressing block 212-1 presses the trigger switch 211-1, and the driving motor 203 drives the numerical control tool 104 to rotate, and the stepping motor 102 stops rotating, completing the precision polishing process of the numerical control tool 104. Repeat multiple times to complete the polishing of multiple numerical control tools 104;

[0052] S3: After the polished numerical control tool 104 moves with the turntable 103, the sliding sleeve 205 arranged below it moves along the inclined sliding ring 207, and it gradually jacks up the eccentric ejector rod 210-1. When the numerical control tool 104 moves directly above the unloading part 207d, the second pressing block 213-1 presses the corresponding trigger switch 211-1, and the stepping motor 102 and the driving motor 203 stop rotating. At this time, the upward jacking stroke of the sliding sleeve 205 is the largest, and the eccentric ejector rod 210-1 neatly unloads the numerical control tool 104 and the socket 202 into the storage box 107 under the guidance of the guiding cover 107a.

[0053] During the use process, insert the numerical control tools 104 that need to be precision polished into the corresponding sockets 202 in sequence, control the turntable 103 to rotate through the stepping motor 102, and send the numerical control tools 104 into the polishing box 105 in sequence. When one of the numerical control tools 104 moves directly above the polishing part, the first pressing block 212-1 presses the trigger switch 211-1, and the driving motor 203 drives the numerical control tool 104 to rotate, and the stepping motor 102 stops rotating, completing the precision polishing process of the numerical control tool 104. Repeat this multiple times to complete the polishing of multiple numerical control tools 104. After the polished numerical control tools 104 move with the turntable 103, the sliding sleeve 205 arranged below it moves along the inclined sliding ring 207, and it gradually jacks up the top plate 209;

[0054] When the numerical control tool 104 moves to directly above the unloading section, the second extrusion block 213-1 extrudes the corresponding trigger switch 211-1, and the stepping motor 102 and the driving motor 203 stop rotating. At this time, the sliding sleeve 205 jacks up with the maximum stroke, and the eccentric ejector rod 210-1 jacks up the socket 202. Under the guidance of the guiding cover 107a, the numerical control tool 104 and the socket 202 are neatly unloaded into the storage box 107, realizing the automatic unloading of the numerically controlled tool 104 that has completed the polishing process. In the large-scale polishing process of the numerically controlled tool 104, the workload of the staff is greatly reduced, and the automation degree of the polishing device is improved.

[0055] Embodiment 2

[0056] Refer to Figure 10 , the difference from Embodiment 1 is that a storage box 107 is placed at one end of the base 101, and a flattening block 107b is fixedly installed on the inner wall of the lower side of the storage box 107. The flattening block 107b is set in a wedge shape. Through the setting of the flattening block 107b, the numerically controlled tool 104 that falls into the storage box 107 through the guiding cover 107a can roll towards the edge of the storage box 107 under the action of its own gravity, effectively solving the defect that the numerically controlled tool 104 is prone to accumulate in the central part of the storage box 107.

[0057] Embodiment 3

[0058] Refer to Figure 1 , the difference from the previous embodiment is that a hydraulic telescopic plate 110 is slidably installed in each strip-shaped opening. The hydraulic telescopic plate 110 can be combined with the feeding of the turntable 103 through electric control, which is often used in the field of polishing the numerically controlled tool 104 and belongs to a very mature existing technology. The specific structure and working principle are not introduced in detail here. A viewing window 106 is inlaid on the side wall of the polishing box 105; through the setting of the hydraulic telescopic plate 110, when sandblasting and polishing the numerically controlled tool 104, the polishing box 105 can be temporarily blocked to form a temporary closed environment to avoid sandblasting scattering. The setting of the viewing window 106 facilitates the staff to directly observe the polishing situation of the numerically controlled tool 104 in the polishing box 105.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
