Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive spray gun production technology, and in particular to a spray gun body processing fixture. Background Technology

[0002] A hot melt adhesive spray gun is a specialized adhesive spraying device primarily used for the precise application of hot melt adhesive. It sprays the adhesive onto designated objects in dots or lines, making it suitable for scenarios requiring linear bonding, such as the bonding of elastic bands to non-woven fabric in pull-up diapers and disposable diapers. The spray gun body includes a base, connecting modules, and other components. To meet the requirements for hot melt adhesive conduction, high-pressure gas conduction, and connection with other components, various through holes, connecting holes, and mounting holes need to be machined on each side of the spray gun body to meet the subsequent assembly and production needs. Current technology for machining spray gun bodies requires first using a machining fixture to clamp and fix the spray gun body at a specified angle. One side of the spray gun body to be machined is aligned with the drill bit of a drilling machine or the cutting head of a milling machine, and then the drilling or milling machine is used to machine that side. When machining the other side of the spray gun body, the clamping and fixing of the spray gun body must be released first, then the angle of the spray gun body is adjusted so that the other side of the spray gun body is aligned with the drill bit of the drilling machine or the cutting head of the milling machine, and then the spray gun body is re-clamped and fixed. Since multiple sides of the spray gun body need to be machined, using existing machining fixtures requires multiple disassembly, angle adjustment, and re-clamping and fixing of the spray gun body, which is time-consuming, labor-intensive, and has low processing efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a spray gun body machining fixture, which facilitates the adjustment of different sides of the spray gun body to align with drilling or milling equipment, making operation convenient and improving processing efficiency.

[0004] A spray gun body machining fixture according to an embodiment of the present utility model includes:

[0005] The clamping mechanism includes a first clamping component and a second clamping component. The first clamping component includes a first clamping block and a first connecting block, which are detachably connected. The second clamping component includes a second clamping block and a second connecting block, which are detachably connected. A processing station is formed between the first clamping block and the second clamping block.

The spray gun body can be rotated via a rotating mechanism to adjust its angle, facilitating alignment with different sides of the drill bit or milling cutter head. Adjusting the spray gun body angle is convenient, improving the efficiency of drilling and milling. The rotating mechanism, in conjunction with the support mechanism, allows the first and second clamping components and the spray gun body to be suspended and easily rotated, facilitating processing of the spray gun body by drilling or milling equipment. A first connecting block is located between the first clamping block and the rotating mechanism, and is detachably connected to both.

Compared with the first clamping block and the second clamping block, the first connecting block and the second connecting block are not directly connected to the spray gun body. Their shape and structure do not need to match the spray gun body to avoid the drill bit of the drilling equipment or the cutter head of the milling equipment. This makes it relatively simple to process replacement parts of different lengths and improves ease of use.

[0012] According to an embodiment of the present invention, a spray gun body processing fixture has a third connecting block in the form of an L-shaped structure, and the L-shaped third connecting block is detachably connected to the first connecting block.

[0013] According to an embodiment of the present invention, a spray gun body processing fixture includes a second clamping assembly that further includes a fourth connecting block.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] Reference Figures 1 to 7 This utility model provides a spray gun body machining fixture, including a clamping mechanism, a rotating mechanism 300, and a supporting mechanism 400. The clamping mechanism includes a first clamping assembly 100 and a second clamping assembly 200. The first clamping assembly 100 includes a first clamping block 110 and a first connecting block 120, which are detachably connected. The second clamping assembly 200 includes a second clamping block 210 and a second connecting block 220, which are detachably connected. A machining station 600 is formed between the first clamping block 110 and the second clamping block 210. Specifically, both the first clamping block 110 and the second clamping block 210 are provided with countersunk through holes. Bolts passing through the countersunk through holes can connect the opposite sides of the spray gun body 700 to the first clamping block 110 and the second clamping block 210 respectively. The rotating mechanism... The rotating mechanism 300 is detachably connected to the first connecting block 120. The rotating mechanism 300 is used to drive the first clamping assembly 100 to rotate, thereby driving the spray gun body 700 connected to the first clamping assembly 100 to rotate. The supporting mechanism 400 is detachably connected to the second connecting block 220. The supporting mechanism 400 is used to rotatably support the second clamping assembly 200. Specifically, the supporting mechanism 400 can support and connect the second clamping assembly 200, and cooperate with the first clamping assembly 100 connected by the rotating mechanism 300 to support the spray gun body 700 connected between the first clamping assembly 100 and the second clamping assembly 200, so that the spray gun body 700 is suspended in the air. Specifically, the supporting mechanism 400 can also realize the relative rotation of the second clamping assembly 200, so that the rotating mechanism 300 drives the first clamping assembly 100, the spray gun body 700 and the second clamping assembly 200 to rotate simultaneously.

[0041] Specifically, refer to Figure 1 and Figure 2The first clamping block 110 and the second clamping block 210 are matched with the outer structure of the spray gun body 700 along the circumferential direction with the length direction of the spray gun body 700 as the axis, so as to facilitate the avoidance of the drill bit of the drilling equipment or the cutting head of the milling equipment.

[0042] Specifically, both the first connecting block 120 and the second connecting block 220 have a variety of replacement parts of different lengths, and the first connecting block 120 and the second connecting block 220 can be replaced according to the required length.

[0043] The first clamping assembly 100 and the second clamping assembly 200 work together to clamp and fix the spray gun body 700 blank to be processed. Furthermore, the spray gun body 700 can be rotated via the rotating mechanism 300 to adjust its angle, facilitating alignment of different sides with the drill bit of the drilling equipment or the cutting head of the milling equipment. Adjusting the angle of the spray gun body 700 is convenient, improving the efficiency of drilling and milling the spray gun body 700. The rotating mechanism 300, in conjunction with the supporting mechanism 400, allows the first clamping assembly 100, the second clamping assembly 200, and the spray gun body 700 to be suspended in the air and easily rotated, facilitating processing of the spray gun body 700 by drilling or milling equipment. The first connecting block 120 is disposed between the first clamping block 110 and the rotating mechanism 300, and the first connecting block 120 is detachably connected to both the first clamping block 110 and the rotating mechanism 300. When it is necessary to process spray gun bodies 700 of different lengths, only the first connecting block 120 of different lengths needs to be replaced to achieve the clamping and fixing of spray gun bodies 700 of different sizes by the spray gun body 700 processing fixture. Alternatively, the purpose of clamping and fixing spray gun bodies 700 of different sizes can be achieved by replacing the second connecting block 220 of different lengths, or by replacing both the first connecting block 120 and the second connecting block 220 simultaneously. Compared with the first clamping block 110 and the second clamping block 210, the first connecting block 120 and the second connecting block 220 are not directly connected to the spray gun body 700. Their external structure does not need to match the spray gun body 700 to avoid the drill bit of the drilling equipment or the cutter head of the milling equipment. This makes it relatively simple to process replacement parts of different lengths and improves the ease of use of the spray gun body 700 processing fixture.

[0044] According to some embodiments of this application, refer to Figure 2 and Figure 3 The first clamping assembly 100 further includes a third connecting block 130, which is disposed between the first connecting block 120 and the rotating mechanism 300. The first connecting block 120 is detachably connected to the rotating mechanism 300 via the third connecting block 130. The third connecting block 130 facilitates the disassembly and installation of the first connecting block 120, improving convenience; moreover, it reduces the disassembly and assembly between the first clamping assembly 100 and the rotating mechanism 300, reducing wear on the rotating mechanism 300.

[0045] Furthermore, the first clamping assembly 100 also includes a first connecting plate 140, which is disposed between the third connecting block 130 and the rotating mechanism 300. The first connecting block 120 is detachably connected to the rotating mechanism 300 via the third connecting block 130 and the first connecting plate 140. When the first connecting block 120 and the third connecting block 130 are disassembled and reassembled multiple times, resulting in wear, the third connecting block 130 needs to be replaced. At this time, it is only necessary to remove the third connecting block 130 from the first connecting plate 140 and reinstall it, further reducing the number of disassemblies and reassemblies between the first clamping assembly 100 and the rotating mechanism 300, and reducing wear on the rotating mechanism 300.

[0046] Furthermore, the third connecting block 130 has an L-shaped structure, and the L-shaped third connecting block 130 is detachably connected to the first connecting block 120. Specifically, the first connecting block 120 is positioned between the horizontal and vertical portions of the L-shaped third connecting block 130. The horizontal portion of the L-shaped third connecting block 130 has vertically provided screw holes, and the bottom side of the first connecting block 120 is connected to the horizontal portion of the L-shaped third connecting block 130 by bolts. The first connecting block 120 and the third connecting block 130 combine to form a rectangle. When it is necessary to disassemble or assemble the first connecting block 120, it is only necessary to remove the bolts from the bottom side of the third connecting block 130, improving the ease of operation.

[0047] According to some embodiments of this application, refer to Figure 2 and Figure 3 The second clamping assembly 200 also includes a fourth connecting block 230, which is disposed between the second connecting block 220 and the support mechanism 400. The second connecting block 220 is detachably connected to the support mechanism 400 via the fourth connecting block 230. This improves the ease of disassembly and installation of the second connecting block 220 and reduces wear on the support mechanism 400.

[0048] Furthermore, the second clamping assembly 200 also includes a second connecting disk 240, which is disposed between the fourth connecting block 230 and the support mechanism 400. The second connecting block 220 is detachably connected to the support mechanism 400 via the fourth connecting block 230 and the second connecting disk 240. This further reduces the number of times the second clamping assembly 200 and the support mechanism 400 are disassembled and assembled, thus reducing wear on the support mechanism 400.

[0049] According to some embodiments of this application, refer to Figure 2 and Figure 3The first clamping block 110 is provided with a first positioning pin 150, and the second clamping block 210 is provided with a second positioning pin 250. The first positioning pin 150 and the second positioning pin 250 are positioned opposite each other on the side of the first clamping block 110 and the second clamping block 210 that are close to each other. Specifically, positioning holes are provided on both sides of the spray gun body 700. After the positioning holes are matched and connected with the first positioning pin 150 and the second positioning pin 250, the positioning and pre-fixation of the spray gun body 700 are realized, which facilitates the installation and connection of the spray gun body 700 with the first clamping block 110 and the second clamping block 210.

[0050] According to some embodiments of this application, refer to Figure 2 , Figure 5 and Figure 6 The rotating mechanism 300 includes a driving component 310 and a driving disk 320. The driving disk 320 is tractively connected to the output end of the driving component 310 and is detachably connected to the first connecting block 120. A scale 330 is provided on the circumferential side of the driving disk 320. The driving component 310 can be a motor, a rotary cylinder, or other device capable of providing rotational drive. The driving component 310 can drive the first clamping assembly 100 to rotate via the driving disk 320, and the scale 330 allows for easy identification of the current rotation angle of the driving disk 320, enabling better angle adjustment of the spray gun body 700 clamped on the machining fixture.

[0051] As a preferred option, refer to Figure 5 The driving component 310 is a rotary cylinder. An air pipe connector 350 is provided on one side of the rotary cylinder. The air pipe connector 350 is used to connect to an external air pipe to obtain an air source to drive the rotary cylinder. Specifically, a protective box 500 is provided on the side of the rotary cylinder where the air pipe connector 350 is located. The protective box 500 is connected to the side of the rotary cylinder where the air pipe connector 350 is located to enclose the air pipe connector 350 and its surrounding space, providing protection for the air pipe connector 350 and its connected air pipe portion, and preventing damage to the air pipe connector 350 and its connected air pipe portion caused by high-temperature metal shavings generated during the processing of the spray gun body 700.

[0052] Furthermore, referring to Figure 6 The rotating mechanism 300 also includes a label, which is correspondingly positioned on the radial outer side of the scale 330. By cooperating with the scale 330, the accuracy of the rotation angle adjustment of the drive disc 320 and the spray gun body 700 is improved.

[0053] According to some embodiments of this application, refer to Figure 2 The support mechanism 400 includes a support frame 410 and a support plate 420. The support frame 410 and the support plate 420 are rotatably connected, and the support plate 420 is detachably connected to the second connecting block 220, thereby improving the support reliability and rotation reliability of the second clamping assembly 200.

[0054] Understandably, referring to Figure 7 In some other embodiments, a bearing 430 is provided between the support frame 410 and the support disk 420. The support frame 410 is rotatably connected to the support disk 420 through the bearing 430, which further improves the smoothness of the relative rotation of the second clamping assembly 200 and reduces its eccentricity.

[0055] Working principle: First, the first positioning pin 150 on the first clamping block 110 and the second positioning pin 250 on the second clamping block 210 are inserted into the positioning holes on both sides of the spray gun body 700 to achieve pre-fixing. Then, bolts are used to pass through the countersunk holes on the first clamping block 110 and the second clamping block 210 and connect them to the opposite sides of the spray gun body 700 to achieve the connection between the first clamping block 110, the second clamping block 210 and the spray gun body 700. Then, for the spray gun body 700 to be processed, a first connecting block 120 and a second connecting block 220 of suitable length are selected. The first clamping block 110 and the second clamping block 210, which are connected to the spray gun body 700, are then connected to the first connecting block 120 with bolts. 0. The second connecting block 220 connects and fixes the first clamping block 110 to the first connecting block 120 and the second clamping block 210 to the second connecting block 220. Next, the first connecting block 120 is placed in relation to the L-shaped third connecting block 130. The first connecting block 120 and the third connecting block 130 are fixed together from the bottom side of the third connecting block 130 using bolts. The second connecting block 220 and the fourth connecting block 230 are also connected and fixed in the same way. Finally, the angle of the spray gun body 700 is rotated by the cooperation of the rotating mechanism 300 and the supporting mechanism 400. After adjusting the different sides of the spray gun body 700 to align with the drilling equipment or milling equipment, the spray gun body 700 is processed by the drilling equipment or milling equipment.

[0056] When it is necessary to disassemble the completed spray gun body 700, simply follow the reverse order of the installation process described above.

[0057] When it is necessary to process spray gun bodies 700 of different lengths, simply replace the first connecting block 120 and the second connecting block 220 with different lengths.
