[0002] Drill bit surface spraying is a surface engineering technology to improve drill bit performance. By spraying the drill bit surface, the drill bit's physical and chemical properties such as wear resistance, corrosion resistance, heat resistance and oxidation resistance can be enhanced.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For specific embodiment 1, please refer to Figure 1-12 The present invention is a surface spraying device for high-precision drill bit processing, including a support component 1. Specifically, the support component 1 includes a hollow support seat 101, and a plurality of arc-shaped limit blocks 102 are symmetrically and slidably arranged on the surface of the hollow support seat 101. An arc-shaped outer rack 103 is slidably arranged on the upper surface of the arc-shaped limit block 102. An arc-shaped slide groove is opened on the upper surface of the arc-shaped limit block 102. The arc-shaped outer rack 103 slides with the arc-shaped slide groove. A support vertical plate is fixedly installed on the upper surface of one of the arc-shaped outer racks 103. A plurality of spray nozzles 104 are fixedly installed on one side of the support vertical plate. The spray nozzles 104 are used to spray paint to spray the drill bit surface.

[0029] Furthermore, a transmission assembly 2 is provided on the surface of the hollow support seat 101, and the transmission assembly 2 includes a transmission support tube 201, and an L-shaped transmission slide 202 is opened on the side surface of the transmission support tube 201. The upper end of the L-shaped transmission slide 202 is a horizontal slide, and the lower end of the L-shaped transmission slide 202 is a vertical slide. A transmission ring 203 is slidably provided on the side surface of the transmission support tube 201, and an arc-shaped transmission block 204 is fixedly connected to the lower surface of the transmission ring 203. The arc-shaped transmission block 204 is slidably matched with the L-shaped transmission slide 202, and an extension frame is fixedly connected to the side surface of the transmission ring 203.

[0030] Furthermore, a sealed control component 3 is fixedly connected to the lower surface of the extension frame, and the sealed control component 3 includes an outer frame 301, and two arc-shaped sealed plates 302 are symmetrically slidably arranged inside the outer frame 301 to control the synchronous sliding of the two arc-shaped sealed plates 302. When the two arc-shaped sealed plates 302 are pressed against each other, a closed space is formed between the arc-shaped sealed plates 302 and the outer frame 301, and a first limit plate 303 is slidably arranged inside the outer frame 301, and two second limit plates 304 are respectively slidably arranged inside the outer frame 301.

[0031] The operation process of this embodiment is as follows: the drill bit to be sprayed is placed between the two second limit plates 304 and the first limit plate 303, the first limit plate 303 and the two second limit plates 304 are controlled to move horizontally synchronously and approach each other until they are in close contact with the side surface of the drill bit, and the arc limit block 102 is controlled to move synchronously and approach each other. In this process, under the sliding cooperation of the arc transmission block 204 and the L-shaped transmission slideway 202, the arc transmission block 204 first moves along the horizontal section of the L-shaped transmission slideway 202, and then drives the closed control component 3 to move synchronously. When the arc transmission block 204 moves to the intersection of the horizontal section and the vertical section of the L-shaped transmission slideway 202, the first limit plate 303 and the two second limit plates 304 drive the drill bit to move to the top of the hollow support seat 101; as the arc limit block 102 continues to move, the arc transmission block 204 moves along the vertical section of the L-shaped transmission slideway 202. The straight section moves downward, driving the drill bit to move downward synchronously. When the lower surface of the drill bit fits with the upper surface of the hollow support seat 101, the lower surfaces of the outer frame 301 and the arc-shaped sealed plate 302 fit with the upper surface of the hollow support seat 101, and the inner wall of the arc-shaped limit block 102 fits tightly against the side surface of the drill bit to limit the position of the drill bit. The arc-shaped limit blocks 102 fit together, controlling the two second limit plates 304 and the first limit plate 303 to move synchronously away from the drill bit. During this process, the two arc-shaped sealed plates 302 move synchronously until the two arc-shaped sealed plates 302 fit together to form a closed space, and the drill bit is located inside the closed space. Then the spray head 104 is started to spray the surface of the drill bit. At the same time, by controlling the movement of the arc-shaped outer rack 103, the spray head 104 is driven to move synchronously, so that the spray head 104 moves along a circular trajectory until a circle of spraying is completed on the side surface of the drill bit.

[0033] Furthermore, a support block is fixedly connected inside the transmission slideway, and a transmission cross bar 113 is slidably provided on the surface of the support block. One end of the transmission cross bar 113 is fixedly connected to a limited transmission block 114, and the limited transmission block 114 is slidably matched with the corresponding transmission adjustment port 106. One end of the limited transmission block 114 is a smooth arc surface, and one end of the smooth arc surface of the limited transmission block 114 fits with the inclined sliding surface of the transmission adjustment port 106. A second return spring 115 is fixedly connected between the limited transmission block 114 and the corresponding support block, and the second return spring 115 is sleeved on the outside of the corresponding transmission cross bar 113. The other end of the transmission cross bar 113 is fixedly connected to an L-shaped transmission plate 116. The arc limit block 102 is connected to the corresponding support block through the support column. The L-shaped transmission plates 116 are fixedly connected, and a transmission rack 117 is fixedly connected to the surface of one of the L-shaped transmission plates 116 through a support frame; a transmission slideway corresponding to the arc-shaped limit block 102 is opened on the surface of the hollow support seat 101, and the support column is slidably arranged inside the corresponding transmission slideway, and the upper surface of the arc-shaped limit block 102 close to the support plate is rotatably connected with an adjusting gear 118, and a first driving motor is fixedly installed on the lower surface of the arc-shaped limit block 102, and the output shaft of the first driving motor is fixedly connected to the adjusting gear 118, the arc-shaped limit blocks 102 are fitted together to form a limiting ring, and the arc-shaped outer racks 103 are fitted together to form a spray outer gear ring, and the adjusting gear 118 is meshed with the spray outer gear ring.

[0034] Furthermore, the transmission support tube 201 is fixedly connected to the upper surface of the hollow support seat 101 through an L-shaped support plate, and a transmission screw 205 is rotatably connected to the upper surface of the hollow support seat 101. The transmission screw 205 is coaxial with the transmission support tube 201 and is located inside the transmission support tube 201; a transmission gear 206 is rotatably arranged at the top inside the hollow support seat 101, the transmission gear 206 is meshed with the transmission rack 117, and the transmission gear 206 and the transmission screw 205 are fixedly connected, and an internal threaded ring 207 is fixedly connected to the inner wall of the arc-shaped transmission block 204 through an extension block, and the internal threaded ring 207 is located inside the transmission support tube 201, and the internal threaded ring 207 and the transmission screw 205 are threadedly matched.

[0035] The operation process of this embodiment is as follows: the power supply of the electromagnet 109 is disconnected, and the magnetic effect of the electromagnet 109 disappears. Under the elastic recovery effect of the first reset spring 111, the guide block slides along the inside of the guide slide groove 108, and the limit rack 112 is driven to move horizontally synchronously through the connection of the guide block. Under the meshing effect of the limit rack 112 and the limit outer gear ring 105, the limit outer gear ring 105 rotates, and the transmission adjustment port 106 moves synchronously with the limit outer gear ring 105. Under the sliding cooperation effect of the inclined inner wall of the transmission adjustment port 106 and the limit transmission block 114, the limit transmission block 114 is squeezed by the inclined inner wall of the transmission adjustment port 106, thereby pushing the limit transmission block 114 to move horizontally, and the transmission cross bar 113 slides horizontally synchronously, the second reset spring 115 is compressed, and the L-shaped transmission plate 116 moves synchronously with the transmission cross bar 113, thereby driving the arc limit block 102 to move synchronously.

[0036] During the movement of the arc limit block 102, the transmission rack 117 moves synchronously with the corresponding arc limit block 102. Under the meshing action of the transmission rack 117 and the transmission gear 206, the transmission gear 206 rotates, thereby driving the transmission screw 205 to rotate. Under the threaded cooperation between the transmission screw 205 and the internal threaded ring 207 and the sliding cooperation between the arc transmission block 204 and the horizontal section of the L-shaped transmission slideway 202, the arc transmission block 204 is not restricted in the horizontal direction. The rotation of the transmission screw 205 drives the internal threaded ring 207 to move synchronously. Under the connection action of the extension block, the arc transmission block 204 slides horizontally along the horizontal section of the L-shaped transmission slideway 202, thereby driving the transmission ring 203 to slide along the side surface of the transmission support tube 201. Under the connection action of the extension frame, the closed control component 3 moves synchronously. When the arc transmission block 204 moves to the intersection of the horizontal section and the vertical section of the L-shaped transmission slideway 202, the closed control component 3 Part 3 drives the drill bit to move to the top of the center of the hollow support seat 101. As the arc-shaped limit block 102 continues to move, the transmission screw 205 continues to rotate, and the arc-shaped transmission block 204 is restricted by the inner wall of the L-shaped transmission slideway 202 and cannot move horizontally. Under the thread cooperation between the transmission screw 205 and the internal thread ring 207, the internal thread ring 207 slides downward along the side surface of the transmission screw 205, thereby driving the arc-shaped transmission block 204 along the L-shaped transmission slideway 202. The vertical section of 02 slides downward, and the transmission ring 203 slides downward synchronously along the peripheral side of the transmission support tube 201, thereby driving the closed control component 3 and the drill bit to move downward synchronously, until the lower surface of the drill bit fits with the upper surface of the hollow support seat 101, the lower surface of the outer frame 301 and the arc-shaped closed plate 302 fits with the upper surface of the hollow support seat 101, and the arc-shaped limit block 102 fits with each other, and the inner wall of the arc-shaped limit block 102 fits tightly with the peripheral side of the drill bit (such as Figure 5 As shown), the position of the drill bit is limited thereby.

[0037] When the drill bit is located inside a confined space, the spray head 104 is started, and at the same time, the first drive motor is started to drive the adjusting gear 118 to rotate. Under the meshing action of the adjusting gear 118 and the corresponding arc-shaped external rack 103, the arc-shaped external rack 103 moves along a circular trajectory, and the remaining arc-shaped external racks 103 move synchronously. Under the connection action of the supporting vertical plate, the spray head 104 is driven to move synchronously to spray the side surface around the drill bit.

[0039] Furthermore, a horizontal section of the U-shaped support frame 308 is slidably matched with the outer frame 301, and one end of the U-shaped support frame 308 that passes through the outer frame 301 is fixedly connected to a second support cross plate, and the second support cross plate is fixedly connected to the first clamping rack 309 on the opposite sides, and the first limit plate 303 is fixedly connected to the second support cross plate; two clamping gears 310 are rotatably arranged at the top of the outer frame 301, the second support cross plate is located between the two clamping gears 310, and a second drive motor is fixedly installed on the upper surface of the outer frame 301, and the output shaft of the second drive motor is connected to the corresponding clamping gear 3 10 is fixedly connected, two clamping grooves are symmetrically opened on the top of the outer frame 301, a clamping frame 311 is slidably arranged inside the clamping groove, the second limit plate 304 is fixedly connected to the corresponding clamping frame 311, and a second clamping rack 312 is fixedly connected to one side of the clamping frame 311, the clamping gear 310 is meshed with the corresponding first clamping rack 309 and the second clamping rack 312, one of the clamping frames 311 is located on the upper side of the second supporting cross plate, and the other clamping frame 311 is located on the lower side of the second supporting cross plate, so as to avoid conflict between the two clamping frames 311 during movement.

[0040] The operation process of this embodiment is as follows: the drill bit is placed between the two second limit plates 304 and the first limit plate 303, and the second driving motor is started to drive the corresponding clamping gear 310 to rotate. Under the meshing action of the clamping gear 310 and the corresponding first clamping rack 309, the second supporting cross plate moves horizontally. Under the meshing action of the other first clamping rack 309 and the other clamping gear 310, the first limit plate 303 moves horizontally. At the same time, the two clamping gears 310 rotate synchronously. Under the meshing action of the two clamping gears 310 and the corresponding second clamping rack 312, the two second clamping racks 312 move horizontally, driving the clamping frame 311 to move synchronously along the corresponding clamping slot, and then the two second limit plates 304 and the first limit plates 303 move synchronously and approach each other until the two second limit plates 304 and the first limit plate 303 are both in close contact with the peripheral side of the drill bit, thereby realizing the position limitation of the drill bit.

[0041] When the arc-shaped transmission block 204 slides along the L-shaped transmission slideway 202, it drives the closed regulating component 3 to move synchronously, so that the closed regulating component 3 moves horizontally first, driving the limited drill bit to move to just above the center of the hollow support seat 101, and then drives the closed regulating component 3 to move downward until the lower surface of the drill bit fits with the upper surface of the hollow support seat 101, the lower surface of the outer frame 301 and the arc-shaped closed plate 302 fits with the upper surface of the hollow support seat 101, and the arc-shaped limit block 102 fits with each other, and the inner wall of the arc-shaped limit block 102 fits tightly with the peripheral side of the drill bit (such as Figure 5 As shown in the figure), the drill bit position is limited, the second drive motor is started to drive the corresponding clamping gear 310 to rotate in the opposite direction, and the second supporting cross plate drives the first limiting plate 303 to move in the opposite direction horizontally. At the same time, the two clamping gears 310 rotate in the opposite direction synchronously, thereby driving the two clamping frames 311 to move in the opposite direction synchronously, and then driving the two second limiting plates 304 to move in the opposite direction synchronously, so that the two second limiting plates 304 and the first limiting plate 303 are away from the drill bit. In this process, the movement of the second supporting cross plate drives the U-shaped supporting frame 308 to move in the opposite direction synchronously horizontally, thereby driving the first supporting cross plate to move synchronously, and the meshing between the closed rack 307 and the corresponding closed gear 306 Under the cooperation, the closed gear 306 rotates synchronously in the opposite direction, and under the meshing action of the closed gear 306 and the arc-shaped inner rack 305, the arc-shaped inner rack 305 slides along the inside of the closed slideway, and the two arc-shaped closed plates 302 move synchronously with the arc-shaped inner rack 305 until the two arc-shaped inner racks 305 fit together to form a closed space, and the drill bit is located inside the closed space. Then the spray head 104 is started to spray the surface of the drill bit. At the same time, by controlling the movement of the arc-shaped outer rack 103, the spray head 104 is driven to move synchronously, so that the spray head 104 moves along a circular trajectory until a circle of spraying operation is completed on the peripheral side of the drill bit.

[0042] After the drill bit is sprayed, the second drive motor is started to drive the corresponding clamping gear 310 to rotate, and the two second limit plates 304 and the first limit plate 303 move synchronously to clamp and limit the drill bit after spraying. At the same time, the two arc-shaped closed plates 302 move in the opposite direction synchronously, and the closed space is opened. The power supply of the electromagnet 109 is turned on, and the limit rack 112 moves in the opposite direction to drive the limit outer gear ring 105 to rotate in the opposite direction, thereby causing the arc-shaped limit block 102 to move horizontally in the opposite direction and move away from each other. During the reverse horizontal movement of the arc-shaped limit block 102, the arc-shaped transmission block 204 slides inside the L-shaped transmission slideway 202, and drives the closed control component 3 to move synchronously through the extension frame, so that the closed control component 3 first moves upward, and then rotates horizontally at a certain angle to return to the initial state, and controls the second limit plate 304 and the first limit plate 303 to move synchronously for a certain distance (both the two clamping frames 311 are in the middle state), and the drill bit after spraying is released. At the same time, the arc-shaped closed plates 302 approach each other (in the middle state between closed and fully open).
