For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0089] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0090] See also Figure 1 , Figure 2 and Figure 3 One embodiment of the present application provides a tool assembly and disassembly device 100 for assembling and disassembling a tool 500. It is well known to those skilled in the art that the tool 500 includes a tool head 310, 320 and a tool handle 200. The tool heads commonly found on the market are generally divided into two types. One type has a bayonet hole reserved on the side wall of the tool head. Figure 3 ), the other is that the side wall of the cutter head has no bayonet (see Figure 2 In this embodiment, a cutting tool 400 for cutting is mounted on the tool head 310, 320 and the tool handle 200. The tool assembly and disassembly device 100 includes a base 10, a plurality of locking mechanisms 20, a support seat 23 and a rotating clamping device 30.

[0091] The support seat 23 is disposed on the base 10. A plurality of locking mechanisms 20 are disposed on the support seat 23 at intervals along a first direction. In the present embodiment, the first direction is the X-axis direction. The plurality of locking mechanisms 20 include at least one first locking mechanism 201 for fixing a cutter head 310 without a bayonet by means of a rotational connection and at least one second locking mechanism 202 for fixing a cutter head 320 with a bayonet by means of a clamping connection. Exemplarily, a portion of the second locking mechanism 202 is inserted into the bayonet of the cutter head 310, and while supporting and fixing the cutter head 310, the cutter head 320 is restricted from rotating relative to the second locking mechanism 202. The first locking mechanism 201 is relative to the cutter head 310. The first locking mechanism 201 is rotated to make the outer peripheral wall of the cutter head 310 close to each other, thereby increasing the friction between the first locking mechanism 201 and the cutter head 310, thereby fixing the cutter head 310 and preventing the cutter head 310 from rotating relative to the first locking mechanism 201, thereby achieving the purpose of fixing the cutter head 310; multiple rotating clamping devices 30 correspond to multiple locking mechanisms 20 one by one and are arranged at intervals along the second direction relative to the locking mechanisms 20. In this embodiment, the second direction is the Z-axis direction. The rotating clamping device 30 is used to clamp the tool handle 200 and rotate the tool handle 200 relative to the cutter heads 310 and 320, thereby disassembling or installing the tool 500. It can be understood that according to actual use requirements, the rotating clamping devices 30 can be two, three, four or more, which is not limited here. In this way, when different types of knives 500 need to be disassembled, it is only necessary to select the corresponding locking mechanism 20 according to the type of the cutter head 310 of the cutter 500. In this way, the knife assembly and disassembly equipment is more versatile, the assembly and disassembly efficiency is improved, and the labor cost is reduced.

[0092] In the following embodiments, two rotating clamping devices 30 are used for explanation.

[0093] In one embodiment, see Figure 4 The first locking mechanism 201 includes a first carrier 21, a first mounting assembly 221 and a first positioning assembly 223. The first carrier 21 is plate-shaped and is disposed on a support seat 23. The first carrier 21 has a first tool installation and disassembly position 211 and a first disassembly position 212 sequentially disposed along a third direction. In the present embodiment, the third direction is the Y-axis direction; the first mounting assembly 221 is slidably disposed on the first carrier 21 between the first tool installation and disassembly position 211 and the first disassembly position 212, and the first mounting assembly 221 is used to lock a tool head 310 without a bayonet; the first positioning assembly 223 is disposed on the first carrier 21, and is used to limit the first mounting assembly 221 to the first tool installation and disassembly position 211.

[0094] Furthermore, the second locking mechanism 202 includes a second carrier 2021, a second mounting assembly 222 and a second positioning assembly 225. The second carrier 2021 is plate-shaped and is disposed on the support seat 23. The second carrier 2021 has a second mounting and disassembly position 2021a and a second disassembly position 2021b sequentially disposed along a third direction; the second mounting assembly 222 can be slidably disposed on the second carrier 2021 between the second mounting and disassembly position 2021a and the second disassembly position 2021b, and the second mounting assembly 222 is used to lock the tool head 320 with a bayonet; the second positioning assembly 225 is disposed on the second carrier 2021, and is used to limit the second mounting and disassembly position 2021a.

[0095] In this way, when the first mounting assembly 221 slides to the first tool mounting and disassembling position 211, the rotating clamping device 30 clamps the tool handle 200 and rotates the tool handle 200 relative to the tool head 310, so that the cutting tool 400 can be mounted and disassembled from the tool head 310 and the tool handle 200. When the first mounting assembly 221 slides to the first disassembly position 212, the first mounting assembly 221 can be disassembled and replaced from the first disassembly position 212. When the second mounting assembly 222 slides to the second tool mounting and disassembly position 2021a, the rotating clamping device 30 clamps the tool handle 200 and rotates the tool handle 200 relative to the tool head 320, so that the cutting tool 400 can be mounted and disassembled from the tool head 320 and the tool handle 200. When the second mounting assembly 222 slides to the second disassembly position 2021b, the second mounting assembly 222 can be disassembled and replaced from the second disassembly position 2021b.

[0096] See also Figure 5 The first carrier 21 and the second carrier 2021 have the same structure. Taking the first carrier 21 as an example, the first carrier 21 is provided with a first slide groove 213 and a second slide groove 214 which are connected in sequence along the third direction. The first slide groove 213 is located at the first tool installation and disassembly position 211, and the second slide groove 214 is located at the first disassembly position 212. The width of the first slide groove 213 is smaller than the width of the second slide groove 214. The first installation component 221 has a slider 2215 slidably connected to the first slide groove 213. The slider 2215 is convexly provided with a limiting protrusion 2215a, which is clamped on the first carrier 21. The width of the limiting protrusion 2215a is greater than the width of the first slide groove 213 and less than the width of the second slide groove 214. Thus, when the first mounting component 221 slides to the first slide groove 213 , the first positioning component 223 can press against the first mounting component 221 to install and remove the cutting tool 400 ; when the first mounting component 221 slides to the second slide groove 214 , the first mounting component 221 can be taken out and replaced at the second slide groove 214 .

[0097] It can be understood that in other embodiments, the groove wall of the first sliding groove 213 is recessed to form at least one limiting groove, and the limiting protrusion 2215a is slidably disposed in the limiting groove.

[0098] In this embodiment, the number of the first installation component 221 and the number of the second installation component 222 are both one. It can be understood that in other embodiments, the number of the first installation component 221 and the number of the second installation component 222 are both three, but the present invention is not limited thereto.

[0099] See also Figure 3 and Figure 6 The first mounting assembly 221 includes a first sliding body 2211, a track-changing member 2212, a retaining member 2213 and a pressing member 2214. The first sliding body 2211 is generally a block-shaped structure, and the first sliding body 2211 is slidably arranged on the bearing member 21; the track-changing member 2212 is arranged in the first sliding body 2211, and the track-changing member 2212 is provided with a receiving hole 2212a, and the hole wall of the receiving hole 2212a is provided with a connected recessed portion 2212b and a protruding portion 2212c; the retaining member 2213 is a rotating body, and the retaining member 2213 is rotatably arranged in the receiving hole 2212a, and the retaining member 2213 is provided with a through hole 2213a and a mounting hole 2213b for accommodating the first blade head 310, and the mounting hole 2213b is provided. 213b is located at the outer periphery of the retaining member 223 and is connected to the through hole 2213a; the tightening member 2214 is rotatably arranged in the mounting hole 2213b, and the tightening member 2214 has a first portion 2214a extending out of the outer periphery of the retaining member 2213 and a second portion 2214b extending into the through hole 2213a, and the maximum radial spacing between the tightening member 2214 and the rotation axis of the retaining member 223 is greater than the radial spacing between the protrusion 2212c and the rotation axis of the retaining member 223, and is smaller than the radial spacing between the recessed portion 2212b and the rotation axis of the retaining member 223.

[0100] See also Figure 7 Initially, the abutting member 2214 corresponds to the recessed portion 2212b, and the second portion 2214b does not abut the cutter head 310, and the cutter head 310 is in an unlocked state; when the cutter head 310 and the handle 200 rotate at the same time, the retaining member 2213 also rotates and drives the abutting member 2214 to rotate until the first portion 2214a abuts against the protruding portion 2212c. Figure 8 As shown, at this time, the second portion 2214b is pressed against the cutter head 310, and the cutter head 310 is in a locked state.

[0101] Among them, the recessed portion 2212b includes a plurality of arc-shaped recessed structures 2212b1 formed by the concave hole wall of the accommodating hole 2212a, the raised portion 2212c is formed between two adjacent arc-shaped recessed structures 2212b1, and the mounting holes 2213b are arranged one by one corresponding to the plurality of raised portions 2212c. Further, the plurality of mounting holes 2213b are arranged along the circumferential array of the retaining member 2213. In this way, when the retaining member 2213 drives the abutting member 2214 to rotate, the plurality of abutting members 2214 gradually and synchronously abut against the cutter head 310, and the locking effect is better. In the present embodiment, the abutting member 2214 is a round pin. In the present embodiment, the cross section of the through hole 2213a is plum blossom-shaped.

[0102] See also Figure 3 and Fig. 9 The second locking mechanism 202 also includes a push-pull driving member 224 arranged opposite to the second positioning assembly 223. The push-pull driving member 224 is slidably arranged on the second bearing member 2021 and is located at the second tool installation and disassembly position 2021a. In this embodiment, the push-pull driving member 224 is a cylinder. The second installation assembly 222 includes a second sliding body 2221, two oppositely arranged inserting members 2222 and a connecting rod assembly 2223. The second sliding body 2221 is roughly a block structure. The second sliding body 2221 is slidably arranged on the second bearing member 2021. The second sliding body 2221 is provided with a knife placement hole 2221a. The two inserting members 2222 are slidably arranged on the second sliding body 2221 and are located around the knife placement hole 2221a. The connecting rod assembly 2223 is slidably disposed on the second sliding body 2221 and is respectively connected to the two inserting members 2222. When the second sliding body 2221 slides to the tool installation and disassembly position 211, the connecting rod assembly 2223 engages with the push-pull driving member 224, so that the two inserting members 2222 are driven to move toward the center of the tool placement hole 2221a by the push-pull driving member 224, so that the two inserting members 2222 are inserted into the bayonet of the tool head 320. In this way, the inserting member 2222 can be inserted into the bayonet of the tool head 320 through the inserting member 2222, the connecting rod assembly 2223 and the push-pull driving member 224.

[0103] Among them, the connecting rod assembly 2223 includes two first connecting rods 2223a, a second connecting rod 2223c and a clamping piece 2223d. The two first connecting rods 2223a are slidably arranged on the second sliding body 2221 and are arranged opposite to each other. One end of each first connecting rod 2223a is provided with an inclined groove 2223b, and the insert 2222 is slidably connected to the inclined groove 2223b. The sliding direction of the first connecting rod 2223a is perpendicular to the sliding direction of the insert 2222; the two ends of the second connecting rod 2223c are respectively rotatably connected to the other ends of the two first connecting rods 2223a; the clamping piece 2223d is arranged between the two ends of the second connecting rod 2223c, and is clamped with the push-pull drive member 224 when the second sliding body 2221 slides to the second tool assembly and disassembly position 2021a.

Taking the first positioning assembly 223 as an example, the first positioning assembly 223 also includes a fixing member 2232, a positioning member 2231 and an elastic member 2233. The fixing member 2232 is a block structure and is disposed on the first bearing member 21; the positioning member 2231 is slidably disposed in the fixing member 2232; the elastic member 2233 is disposed in the fixing member 2232, one end of the elastic member 2233 abuts against the fixing member 2232, and the other end of the elastic member 2233 abuts against the positioning member 2231. The elastic member 2233 is used to make the positioning member 2231 elastically press against the first mounting assembly 221 or the second mounting assembly 222. In this embodiment, the elastic member 2233 is a spring and is sleeved on the positioning member 2231. In this way, by arranging the elastic member 2233 and the positioning member 2231 in the fixing member 2232 , the positioning member 2231 can be elastically pressed against the first sliding body 2211 of the first mounting assembly 221 to prevent the first sliding body 2211 from being scratched.

[0105] The fixing member 2232 has a first sliding hole 2232a, a second sliding hole 2232bb and a limiting groove 2232c that are connected to each other. The inner diameter of the first sliding hole 2232a is larger than the inner diameter of the second sliding hole 2232bb. The positioning member 2231 includes a sliding portion 2231a, an abutting portion 2231d and a limiting portion 2231e. The sliding portion 2231a is columnar and is slidably inserted in the first sliding hole 2232a and the second sliding hole 2232bb. The sliding portion 2231a has a relative abutting end 2231b and a pull-push end 2231c; the abutting portion 2231d is annular and is arranged on the sliding portion 2231d. The movable part 2231a is located in the first sliding hole 2232a, the size of the abutting part 2231d is larger than the inner diameter of the second sliding hole 2232bb, the elastic member 2233 is arranged in the first sliding and its two ends are respectively abutted against the abutting part 2231d and the fixing member 2232; the limiting part 2231e is block-shaped, the limiting part 2231e is arranged at the pulling and pushing end 2231c and is contoured with the limiting groove 2232c, and the limiting part 2231e is used to be accommodated in the limiting groove 2232c when the tightening end 2231b is pressed against the first mounting component 221, and to move out of the limiting groove 2232c when the tightening end 2231b releases the first mounting component 221. Thus, by pulling the push-pull end 2231c of the sliding portion 2231a outward, the limiting portion 2231e can be moved out of the limiting groove 2232c, so that the positioning member 2231 does not abut against the first mounting assembly 221; and the size design of the abutting portion 2231d can prevent the sliding portion 2231a from sliding out of the fixing member 2232. In this embodiment, the abutting end 2231b can extend into the first sliding body 2211, and the abutting portion 2231d abuts against the first sliding body 2211.

[0106] Please continue to see Figure 4 , the first locking mechanism 201 and the second locking mechanism 203 are both slidably arranged on the support seat 23 along the second direction, and the knife assembly and disassembly device 20 also includes a plurality of lifting mechanisms 24, which are arranged on the support seat 23 and are respectively connected to the first locking mechanism 201 and the second locking mechanism 203, and are used to drive the first locking mechanism 201 and the second locking mechanism 203 to slide along the second direction on the support seat 23. In this embodiment, the lifting mechanism 24 is a cylinder. In this way, by setting the lifting mechanism 24 to control the lifting and lowering of the first locking mechanism 201 and the second locking mechanism 203, it is convenient to rotate the clamping device 30 to clamp the knife handle 200.

[0107] Please continue to see Figure 1The rotary clamping device 30 includes a clamping member 31 for clamping the tool handle 200 and a rotary driving member 32. The rotary driving member 32 is disposed on the base 10 and connected to the clamping member 31, and is used to drive the clamping member 31 to drive the tool handle 200 to rotate, so as to assemble and disassemble the cutting tool 400. In this embodiment, the clamping member 31 is a clamping claw, and the rotary driving member 32 is a motor. Through the cooperation of the clamping member 31 and the rotary driving member 32, the cutting tool 400 can be quickly assembled and disassembled.

[0108] The implementation process of the above-mentioned knife assembly and disassembly device 100 is as follows:

[0109] Install two different cutting tools 500 into the clamping members 31 corresponding to the first locking mechanism 201 and the second locking mechanism 203 respectively;

[0110] The two lifting mechanisms 24 drive the corresponding first locking mechanism 201 and the second locking mechanism 203 to move toward the clamping member 31, so that the through hole 2213a of the retaining member 2213 accommodates the cutter head 310, and the cutter hole 2221a accommodates the cutter head 320;

[0111] The positioning member 2231 slides in the fixing member 2232 toward the first mounting assembly 221, and the abutting end 2231b extends into the first sliding body 2211. At this time, the abutting portion 2231d abuts against the first sliding body 2211, and the limiting portion 2231e is received in the limiting groove 2232c, thereby locking the first mounting assembly 221. The rotating driving member 32 drives the clamping member 31 to drive the knife handle 200 and the knife head 310 to rotate simultaneously, so that the second portion 2214b abuts against the first sliding body 2211. The cutter head 310 is then rotated, and the driving member 32 is then rotated to continue driving the clamping member 31 to drive the handle 200 to rotate relative to the cutter head 310, so that the cutter head 310 and the handle 200 unlock the cutting knife 400, and the cutting knife 400 is removed and replaced with a new cutting knife 400 of the same type, and then the driving member 32 is rotated to drive the clamping member 31 to rotate in the opposite direction, so that the cutter head 310 and the handle 200 lock the cutting knife 400, and then the locked cutter head 310 and the handle 200 can be removed for use;

[0112] At the same time, the push-pull driving member 224 drives the connecting rod assembly 2223 to drive the two inserting members 2222 to move toward the center of the knife hole 2221a, so that the two inserting members 2222 are inserted into the bayonet of the cutter head 320, and the rotating driving member 32 drives the clamping member 31 to drive the handle 200 to rotate relative to the cutter head 320, and the cutter head 320 unlocks the cutting knife 400, and the cutting knife 400 is removed and replaced with a new cutting knife 400 of the same type; then the rotating driving member 32 drives the clamping member 31 to drive the cutter head 320 to rotate in the opposite direction relative to the handle 200, and the cutter head 320 and the handle 200 lock the cutting knife 400, and then the locked cutter head 320 and the handle 200 can be taken out for use;

[0113] When it is necessary to disassemble the first installation component 221 and the second installation component 222, the first positioning component 223 unlocks the first installation component 221 and slides the first installation component 221 to the first disassembly position 212 for disassembly, removes the first installation component 221 and replaces it with another first installation component 221; and the second positioning component 225 unlocks the second installation component 222 and slides the second installation component 222 to the second disassembly position 2021b for disassembly.

[0114] The above-mentioned tool assembly and disassembly device 100 includes a tool assembly and disassembly device 20, which locks the tool head 310 without a bayonet through a first locking mechanism 201, and locks the tool head 320 with a bayonet through a second locking mechanism 202, and then clamps the tool handle 200 through a rotating clamping device 30 and rotates the tool handle 200 relative to the tool heads 310, 320, so as to disassemble or install the tool 500. It can adapt to the assembly and disassembly of tools 500 with and without bayonet, and the labor intensity is small when assembling and disassembling the tool 500, less manpower is required, and the assembly and disassembly efficiency is high.
