Technical Field

[0001] This invention relates to the field of metal cutting equipment technology, specifically a fixing device for tapping metal stamping parts. Background Technology

[0002] Metal stampings are widely used due to their robust structure and strong adaptability. Tapping is a key process in the production and manufacturing of stampings.

[0003] Patent application CN202121159829.8 discloses a fixing device for tapping metal stamping parts, including a positioning device. The positioning device includes a positioning frame, a positioning plate, a slot, a threaded hole, a bolt, and a positioning hole. The positioning frame is installed on the top of the base. The outer wall of the top of the positioning frame has multiple threaded holes, and a bolt is installed in one of the threaded holes. The positioning frame has a slot, and the positioning plate is embedded into the positioning frame through the slot. The other end of the positioning plate is sleeved on the bottom of the stamping device, and the outer wall of the top of the positioning plate has multiple positioning holes. The bolt passes through the threaded hole and is threadedly connected to the positioning hole.

[0004] However, during the process of fixing the stamped parts in the tapping process, the irregular shape of the stamped parts leads to poor stability of the stamped parts being held, which causes the stamped parts to shake or shift during the tapping process, affecting the thread processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a fixing device for tapping metal stamping parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixed tool device for tapping metal stamping parts, comprising a bed and a worktable, wherein a tapping gun is fixedly connected to the surface of the worktable via a support frame, and a clamping mechanism is provided on the top of the worktable;

[0007] The clamping mechanism includes a swing block. A guide groove is formed on the outer wall of the swing block. A clamping block is slidably connected to the guide groove via a slider. The clamping block is disposed inside the swing block. An air bladder is fixedly connected to the inner wall of the swing block. One end of the air bladder near the clamping block contacts the outer wall of the clamping block to support the clamping block. The clamping block protrudes from the outer wall of the swing block and fits against the irregular surface of the outer wall of the stamping part through the inflation of the air bladder, thus supporting and clamping the stamping part. The swing block is driven to swing adaptively by the reaction force after the clamping block contacts the outer wall of the stamping part, increasing the contact area between the clamping block and the outer wall of the stamping part and preventing the clamping block from damaging the stamping part.

[0008] According to the above technical solution, the clamping block has a pressure groove on the outer wall near the airbag and a recovery hole on the side away from the airbag. The inner wall of the clamping block is provided with a support mechanism, which includes a support rod. The outer wall of the support rod is slidably connected to the inner wall of the clamping block. A second pressure block is fixedly connected to the end of the support rod away from the airbag. The outer wall of the second pressure block is slidably connected to the wall of the recovery hole. The second pressure block is used to support the stamping part.

[0009] According to the above technical solution, a spring is fixedly connected to the outer wall of the support rod, and the other end of the spring is fixedly connected to the inner wall of the clamping block. The support rod is supported by the spring so that the end of the support rod away from the pressure block contacts the outer wall of the airbag. The airbag is filled with gas to generate deformation and enter the pressure groove to support the support rod, so that the pressure block clamps and supports the stamping part. The pressure block is made of rubber to increase the friction between the clamping block and the stamping part and prevent the stamping part from shifting during the tapping process.

[0010] According to the above technical solution, an air pump is installed inside the bed, and the output end is connected to the inside of the air bladder through a hose for inflating the air bladder. The outer wall of the worktable is slidably connected to the inner wall of the bed, and the worktable is driven to adjust up and down on the inner wall of the bed by a servo motor installed inside the bed. An electric push rod is fixedly connected to the surface of the worktable, and a support plate is fixedly connected to the output end of the electric push rod. The electric push rod is used to drive the support plate to adjust up and down.

[0011] According to the above technical solution, a support platform is slidably connected to the inner wall of the workbench. The support platform is driven by a pneumatic cylinder set at the bottom of the workbench and can be adjusted up and down along the inner wall of the workbench. The support platform is used to support the bottom of the stamped part. A level detector is fixedly connected to the inner wall of the support plate. The level detector detects the levelness of the tapped surface of the stamped part by emitting horizontal infrared light.

[0012] According to the above technical solution, a guide groove is provided on the surface of the worktable, and an adjustment mechanism is provided on the surface of the worktable. The adjustment mechanism includes an adjustment platform, the bottom of which slides along the surface of the worktable. The bottom of the adjustment platform is slidably connected to the wall of the guide groove via a slider. The guide groove is used to limit the direction of the adjustment platform by the slider. An adjustment block is slidably connected to the surface of the adjustment platform. A bidirectional push rod is fixedly connected to the top of the adjustment block. A positioning block is fixedly connected to the top output end of the bidirectional push rod. The positioning block positions and supports the stamping part by inserting into the positioning hole of the stamping part.

[0013] According to the above technical solution, the surface of the adjustment platform is provided with a second guide groove, and the bottom of the adjustment block is slidably connected to the wall of the second guide groove through a slider. The second guide groove is used to limit the direction of the adjustment block through the slider. The outer wall of the positioning block is hinged to the inner wall of the swing block through a bearing. The positioning block is used to support and limit the swing block.

[0014] According to the above technical solution, the bottom output end of the bidirectional push rod is fixedly connected to the pressure block 1 through the guide groove 2. The bidirectional push rod is used to drive the pressure block 1 to contact the worktable surface and fix the adjustment table and the adjustment block on the worktable surface by friction. The bidirectional push rod is used to drive the positioning block to adjust the height of the stamping part and adjust the tapping surface of the stamping part to be horizontal. There are four sets of adjustment mechanisms and clamping mechanisms. The four sets of adjustment mechanisms and clamping mechanisms are symmetrically arranged on the worktable surface with the center line of the worktable as the axis of symmetry. Each set of adjustment mechanisms and clamping mechanisms can be independently adjusted to support and fix the stamping part.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention supports the clamping block by inflating an airbag, allowing the clamping block to adjust its position through airbag expansion and fit more closely to the outer wall of the stamping part, increasing the contact area for clamping the stamping part, preventing the stamping part from shaking during tapping and causing the stamping part to shift position, and increasing the stability of the metal cutting device in clamping the stamping part.

[0017] 2. The present invention uses the reaction force of the clamping block on the stamping to drive the swing block to swing adaptively, thereby increasing the contact area of ​​the clamping block on the stamping after clamping, preventing the contact area between the clamping block and the workpiece after clamping irregular stamping from being too small, which would cause damage to the outer wall of the stamping, and increasing the stability of the metal cutting device in clamping the stamping.

[0018] 3. The present invention provides support for the stamped part by setting a second pressure block made of rubber material inside the clamping block, thereby increasing the friction force of the clamping block after clamping the stamped part, increasing the stability of the clamping block after clamping the stamped part, reducing the shaking of the stamped part during the tapping process, and increasing the stability of the metal cutting device in clamping the stamped part.

[0019] 4. The present invention supports the irregular positioning holes of the stamped part by setting an adjustment mechanism that can be independently adjusted in position, and drives the stamped part to adjust its position so that the tapping surface of the stamped part is kept in a horizontal position for tapping, thereby increasing the accuracy of the metal cutting device in tapping the stamped part.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1, please refer to Figures 1-2 and Figures 6-7 The present invention provides a technical solution: a fixed tool device for tapping metal stamping parts, including a bed 100 and a worktable 102, a tapping gun 101 fixedly connected to the surface of the worktable 102 by a support frame, and a clamping mechanism 300 provided on the top of the worktable 102.

[0031] During the tapping process of metal stamping parts, the irregular shape of the stamping parts leads to poor clamping stability, causing them to wobble or shift during tapping, affecting the thread processing accuracy. Therefore, an airbag 304 is inflated to support the clamping block 303, allowing the clamping block 303 to adjust its position through the expansion of the airbag 304 and fit more closely to the outer wall of the stamping part. This increases the contact area for clamping the stamping part, preventing it from wobbling during tapping and causing positional shift. This also increases the stability of the metal cutting device clamping the stamping part. Simultaneously, the reaction force of the clamping block 303 on the stamping part causes the swing block 301 to swing adaptively, increasing the contact area of ​​the clamping block 303 after clamping the stamping part. This prevents the contact area between the clamping block 303 and the workpiece from being too small after clamping irregular stamping parts, which could damage the outer wall of the stamping part. This further increases the stability of the metal cutting device clamping the stamping part.

[0032] The clamping mechanism 300 includes a swing block 301. A guide groove 302 is formed on the outer wall of the swing block 301. A clamping block 303 is slidably connected to the groove wall of the guide groove 302 via a slider. The clamping block 303 is disposed inside the swing block 301. An air bladder 304 is fixedly connected to the inner wall of the swing block 301. One end of the air bladder 304 near the clamping block 303 contacts the outer wall of the clamping block 303, providing support for the clamping block 303. The clamping block 303 protrudes from the outer wall of the swing block 301 through the inflated air bladder 304, fitting against the irregular surface of the outer wall of the stamped part, thus supporting and clamping the stamped part. The swing block 301, through the reaction force after the clamping block 303 contacts the outer wall of the stamped part, drives the swing block 301 to swing adaptively, increasing the contact area between the clamping block 303 and the outer wall of the stamped part, preventing the clamping block 303 from damaging the stamped part. An air pump is installed inside the bed 100, and its output end is connected to... The hose is connected to the inside of the airbag 304 for inflating the airbag 304. The outer wall of the worktable 102 is slidably connected to the inner wall of the bed 100, and the worktable 102 is driven to move up and down on the inner wall of the bed 100 by a servo motor installed inside the bed 100. An electric push rod 104 is fixedly connected to the surface of the worktable 102, and a support plate 105 is fixedly connected to the output end of the electric push rod 104. The electric push rod 104 is used to drive the support plate 105 to move up and down. A support platform 107 is slidably connected to the inner wall of the worktable 102. The support platform 107 is driven by a pneumatic cylinder installed at the bottom of the worktable 102 and can be adjusted up and down along the inner wall of the worktable 102. The support platform 107 is used to support the bottom of the stamped part. A level detector 106 is fixedly connected to the inner wall of the support plate 105. The level detector 106 detects the levelness of the tapped surface of the stamped part by emitting horizontal infrared light.

[0033] When the fixed tool for tapping metal stamping parts is put into use, the position of the adjusting mechanism 200 is adjusted to position and support the stamping part through the positioning hole, and the height of the stamping part is adjusted. The electric actuator 104 is activated to drive the support plate 105 to drive the level detector 106 to adjust the height. The level detector 106 detects the levelness of the tapping surface of the stamping part and feeds back to the adjusting mechanism 200 to continue adjusting the stamping part. When the tapping surface of the stamping part is adjusted to be level, the air pump installed inside the bed 100 is activated to inflate the airbag 304. The airbag 304 expands inside the swing block 301 to support the clamping block 303. The clamping block 303 is guided by the guide groove 302 to slide on the inner wall of the swing block 301 and protrudes from the outer wall of the swing block 301 to contact the outer wall of the stamping part. The expansion causes the clamping block 303 to contact the irregular surface of the outer wall of the stamping part, clamping the stamping part. During the clamping process, the clamping block 303 is driven by the reaction force of the stamping part to swing the swing block 301, increasing the contact area between the clamping block 303 and the outer wall of the stamping part, preventing the clamping block 303 from damaging the outer wall of the stamping part. After the stamping part is clamped, the pneumatic cylinder at the bottom of the worktable 102 drives the support table 107 to support the bottom of the stamping part. The operator adjusts the tapping gun 101 to make it coaxial with the hole channel to be tapped in the stamping part. The tapping gun 101 is started and the servo motor at the inner wall of the bed 100 drives the worktable 102 to slide upward inside the bed 100, so that the tapping gun 101 taps the hole channel to be tapped in the stamping part.

[0034] Example 2, based on Example 1, please refer to... Figures 7-8 The present invention provides a technical solution: a pressure groove 306 is provided on the outer wall of the clamping block 303 near the airbag 304, a retrieval hole 305 is provided on the side of the clamping block 303 away from the airbag 304, and a support mechanism 400 is provided on the inner wall of the clamping block 303.

[0035] During the tapping process of metal stamping parts, the irregular shape of the stamping parts leads to poor clamping stability, causing them to wobble or shift during tapping, which affects the thread processing accuracy. Therefore, a rubber pressure block 402 is installed inside the clamping block 303 to support the stamping parts, further increasing the friction after the clamping block 303 clamps the stamping parts, increasing the stability of the clamping block 303 after clamping the stamping parts, reducing the wobble of the stamping parts during tapping, and increasing the stability of the metal cutting device clamping the stamping parts.

[0036] The support mechanism 400 includes a support rod 401, the outer wall of which is slidably connected to the inner wall of the clamping block 303. A pressure block 402 is fixedly connected to the end of the support rod 401 away from the airbag 304. The outer wall of the pressure block 402 is slidably connected to the wall of the recovery hole 305. The pressure block 402 is used to support the stamped part. A spring 403 is fixedly connected to the outer wall of the support rod 401. The other end of the spring 403 is fixedly connected to the inner wall of the clamping block 303. The support rod 401 is supported by the spring 403 so that the end of the support rod 401 away from the pressure block 402 contacts the outer wall of the airbag 304. The airbag 304 is filled with gas and deforms to enter the pressure groove 306 to support the support rod 401. The pressure block 402 clamps and supports the stamped part. The pressure block 402 is made of rubber and is used to increase the friction between the clamping block 303 and the stamped part to prevent the stamped part from shifting during the tapping process.

[0037] After the airbag 304 expands inside the swing block 301 by inflation, it drives the clamping block 303 to contact the outer wall of the stamping part. The airbag 304 then expands into the pressure groove 306 to support the support rod 401. The support rod 401 compresses the spring 403, causing the pressure block 402 to slide towards the stamping part. The pressure block 402 is guided by the recovery hole 305 and slides on the inner wall of the recovery hole 305, protruding from the outer wall of the clamping block 303 to support the stamping part. The support rod 401 also compresses the pressure block 402, increasing the friction between the clamping block 303 and the outer wall of the stamping part. This prevents the stamping part from shifting during the tapping process and increases the stability of the tapping of the stamping part by the fixing device for tapping the metal stamping part.

[0038] Example 3, based on Examples 1 and 2, please refer to... Figures 3-5 The present invention provides a technical solution: a guide groove 103 is provided on the surface of the workbench 102, and an adjustment mechanism 200 is provided on the surface of the workbench 102;

[0039] During the fixing process of the metal stamping part in the tapping process, the irregular shape of the stamping part leads to poor stability of the stamping part clamping, which causes the stamping part to shake or shift during the tapping process, affecting the thread processing accuracy. Therefore, an adjustment mechanism 200 that can be independently adjusted is set to support the irregular positioning hole of the stamping part and drive the stamping part to adjust its position, so that the tapping surface of the stamping part is kept in a horizontal position for tapping, thereby increasing the accuracy of the metal cutting device in tapping the stamping part.

[0040] The adjusting mechanism 200 includes an adjusting table 201. The bottom of the adjusting table 201 slides along the surface of the worktable 102. The bottom of the adjusting table 201 is slidably connected to the wall of the first guide groove 103 via a slider. The first guide groove 103 is used to limit the direction of the adjusting table 201 via the slider. An adjusting block 203 is slidably connected to the surface of the adjusting table 201. A bidirectional push rod 205 is fixedly connected to the top of the adjusting block 203. A positioning block 204 is fixedly connected to the top output end of the bidirectional push rod 205. The positioning block 204 positions and supports the stamped part by inserting into the positioning hole of the stamped part. A second guide groove 202 is opened on the surface of the adjusting table 201. The bottom of the adjusting block 203 is slidably connected to the wall of the second guide groove 202 via a slider. The second guide groove 202 is used to limit the direction of the adjusting block 203 via the slider. The outer wall of the positioning block 204 is connected by a shaft. The pivot block 301 is hinged to the inner wall of the pivot block 301. The positioning block 204 is used to support and limit the pivot block 301. The bottom output end of the bidirectional push rod 205 passes through the guide groove 202 and is fixedly connected to the pressure block 206. The bidirectional push rod 205 is used to drive the pressure block 206 to contact the surface of the worktable 102, and fix the adjustment table 201 and the adjustment block 203 on the surface of the worktable 102 by friction. The bidirectional push rod 205 is used to drive the positioning block 204 to adjust the height of the stamping part and adjust the tapping surface of the stamping part to be horizontal. There are four sets of adjustment mechanism 200 and clamping mechanism 300. The four sets of adjustment mechanism 200 and clamping mechanism 300 are symmetrically arranged on the surface of the worktable 102 with the center line of the worktable 102 as the axis of symmetry. Each set of adjustment mechanism 200 and clamping mechanism 300 can be independently adjusted to support and fix the stamping part.

[0041] Before the stamped part is clamped by the clamping mechanism 300, the operator pushes the bidirectional push rod 205, causing it to drive the adjusting table 201 via the adjusting block 203. The adjusting table 201 slides on the surface of the worktable 102 guided by the first guide groove 103. Simultaneously, the adjusting block 203 slides on the surface of the adjusting table 201 guided by the second guide groove 202. The operator then adjusts the positioning block 204 to the positioning hole of the stamped part by independently adjusting the position of each set of bidirectional push rods 205, and aligns the stamped part with the positioning hole and positioning block 204. The inclined outer wall is inserted to support the stamping part with the positioning block 204. After the stamping part is placed, the bidirectional push rod 205 is activated to drive the pressure block 206 to descend and contact the surface of the worktable 102. The adjustment table 201 and the adjustment block 203 are fixed in position by friction. At the same time, the positioning block 204 is adjusted up and down. The horizontal detector 106 detects and provides feedback on the horizontality of the tapping surface of the stamping part. The bidirectional push rod 205 drives the positioning block 204 to adjust the position of the stamping part so that the stamping surface is in a horizontal position for tapping.

The bidirectional push rod (205) is used to drive the positioning block (204) to adjust the height of the stamping part and adjust the tapping surface of the stamping part to be horizontal. There are four sets of adjustment mechanism (200) and clamping mechanism (300). The four sets of adjustment mechanism (200) and clamping mechanism (300) are symmetrically arranged on the surface of the worktable (102) with the center line of the worktable (102) as the axis of symmetry. Each set of adjustment mechanism (200) and clamping mechanism (300) can be independently adjusted to support and fix the stamping part.
