[0016] A method for using a protective fixture device for lamp processing, comprising the following steps:

[0017] S1. Move the adjustment arm and press the buttons on both sides of the slider. The buttons drive the inclined surfaces on the buttons to contact the inclined surfaces on the driving block, so that the driving block stretches the tension spring. At the same time, one circle of the driving block translates toward the outside of the installation cavity. During the process, the driving block drives the plug rod to disengage from the inside of the circular groove through the connecting plate, so that the slider can be removed from the adjustment ring or the slider can be directly pushed to slide along the adjustment ring to select the clamping position.

[0018] S2, after the adjustment arm is moved down and the positions of the slider and the adjustment arm are selected, the button is released, the tension spring is reset to pull the driving block, and the driving block contacts the inclined surface of the button through the inclined surface on the driving block, so that the button is reset.

[0020] S4, under the moving slide, when the position of the slide is adjusted, the pressure plate is released to break away from the conflict with the transmission block, and the second spring rebounds to drive the transmission block to reset, so that the transmission block drives the second inclined block to break away from the conflict with the first inclined block. At this time, the first spring rebounds to conflict with the first inclined block and the movable block to reset, and the movable block again conflicts with the two limit blocks and enters between the two limit blocks, so that the two sides of the movable block conflict with the direct surfaces of the two limit blocks. During the process, one end of the limit block conflicts with the tooth block, so that the tooth block is locked with the tooth groove;

[0021] S5. Move the clamping arm. After the position of the slide is adjusted, rotate the screw rod to drive the clamping arm to slide on the slide. During the sliding process of the clamping arm, the through slot slides on the transmission block.

[0022] Compared with the prior art, the present invention provides a protective fixture device and method for lamp processing, which has the following beneficial effects:

DETAILED DESCRIPTION

[0031] 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.

[0032] See also Figure 1-5 A protective fixture device and method for lamp processing includes a processing table 1, an adjustment ring 11 is fixedly arranged on the top of the processing table 1, and a plurality of adjustment arms 2 are arranged on the adjustment ring 11.

[0033] A tooth groove 21 is formed on one side of the adjusting arm 2 , a slider 22 engaged with the adjusting ring 11 is disposed at one end of the adjusting arm 2 , and at least one clamp assembly 3 is movably sleeved on the adjusting arm 2 .

[0034] The clamp assembly 3 includes a clamping arm 31 and a slide seat 32 movably mounted inside the clamping arm 31, the slide seat 32 is movably mounted on the adjusting arm 2, and pressure plates 314 are movably mounted on both sides of the inner wall of the clamping arm 31. A driving cavity 33 and a movable cavity 35 are respectively opened inside one side of the slide seat 32, and a tooth block 38 with one end extending into the tooth groove 21 and meshing with the tooth groove 21 is arranged inside the movable cavity 35. Multiple clamp assemblies 3 can be installed on a single adjusting arm 2, and the assembly can be completed by simply inserting the slide seat 32 from the top of the adjusting arm 2. A single adjusting arm 2 is designed with multiple clamp assemblies 3, and multiple adjusting arms 2 are used at the same time, which can meet the clamping requirements of different shapes and sizes, greatly improving the clamping protection effect of lamp products, and selecting the thicker part of the lamp product for clamping can effectively reduce damage to the lamp product, meeting the processing and use requirements of users.

[0035] A movable block 34 is movably provided inside the driving chamber 33 through a spring 342, and inclined blocks 341 are provided on both sides of the movable block 34. Limiting blocks 36 are hinged on both sides of the inner wall of the movable chamber 35, and one end of the limiting block 36 abuts against one end of the tooth block 38 away from the tooth groove 21, and a straight surface 361 is provided on one side of the limiting block 36. The end of the movable block 34 away from the spring 342 extends between the two limiting blocks 36 and the two sides of the movable block 34 fit with the straight surfaces 361 of the two limiting blocks 36. A transmission block 37 is also provided inside the driving chamber 33, with one end extending to one side of the pressure plate 314 and the other end abutting against the inclined block 341.

[0036] As a specific technical solution of this embodiment, the end of the limit block 36 that contacts the tooth block 38 and the end away from the tooth block 38 are both arc surfaces, and a compression spring is embedded on the side of the limit block 36 away from the straight surface 361. The number of the spring 1 342 is not less than one, and the elastic force of the spring 1 342 is greater than the compression spring. When the inclined block 2 371 is separated from the contact limit of the inclined block 1 341, the movable block 34 can be always located between the two limit blocks 36 through the multiple springs 1 342. Figure 5 , two short springs are also provided on both sides of the tooth block 38, and the short springs continuously apply a force to the tooth block 38 to resist the tooth groove 21, so that when the tooth block 38 resists the tooth groove 21 and retreats, it can quickly rebound and resist the tooth groove 21 again. The design of the arc surface ensures that when the compression spring resists the limit block 36 and flips, it will not resist the tooth block 38 and get stuck. The two sides of the movable block 34 are also straight surfaces 361. When the movable block 34 enters between the two limit blocks 36 and resists the straight surfaces 361 on the two limit blocks 36, continue to refer to Figure 5 The movable block 34 does not directly conflict with the tooth block 38, and the force of the tooth block 38 retreating is transmitted to the limit block 36. The contact surface between the limit block 36 and the movable block 34 is the straight surface 361, so the limit block 36 and the movable block 34 will be stuck, so that the tooth block 38 is locked and cannot retreat. The width of the movable cavity 35 is less than the sum of the lengths of the two limit blocks 36, so that when the two limit blocks 36 are relatively flipped by the compression spring to disengage from the conflict with the tooth block 38, there will be no excessive flipping, so that the movable block 34 can easily push the two limit blocks 36 apart.

[0037] As a specific technical solution of this embodiment, through grooves 313 are provided on both sides of the inner wall of the clamping arm 31, and the pressure plate 314 is movably sleeved inside the through groove 313. One end of the transmission block 37 on one side of the pressure plate 314 is sleeved with the through groove 313, and the other end of the transmission block 37 is provided with an inclined block 2 371, and the end of the inclined block 2 371 away from the transmission block 37 is in conflict with one side of the inclined block 1 341.

[0038] As a specific technical solution of this embodiment, the side of the pressure plate 314 away from the transmission block 37 extends to the side of the clamping arm 31, and the end of the transmission block 37 away from the pressure plate 314 is provided with a spring 2 372, and the interior of the driving cavity 33 is also fixedly provided with a limit rod with one end movably sleeved with the interior of the transmission block 37, see Figure 5 The setting of the limit rod ensures the stability of the transmission block 37.

[0039] As a specific technical solution of this embodiment, one end of the clamping arm 31 is connected to the clamping head 311 through a fastener 312, and the angle between the two ends of the adjusting arm 2 is less than 90 degrees. One side of the sliding seat 32 is rotatably provided with a screw rod 39 threadedly sleeved with the clamping arm 31 through a bearing. The design of the angle between the two ends of the adjusting arm 2 being less than 90 degrees ensures that when multiple adjusting arms 2 rotate on the adjusting ring 11, their top ends will not conflict with each other. The fastener 312 is a conventional fastening hardware such as a screw or a bolt. The fastener 312 facilitates the disassembly and replacement of different types of clamping heads 311, thereby further increasing the versatility of the product.

[0040] As a specific technical solution of this embodiment, a plurality of circular grooves 12 are opened on the inner wall of the adjustment ring 11, and the slider 22 is in an inverted U shape, with both ends of the slider 22 extending to the inner wall and the outer wall of the adjustment ring 11 respectively.

[0041] As a specific technical solution of this embodiment, an installation cavity is opened inside the slider 22, and a driving block 23 is movably arranged inside the installation cavity through a tension spring 26. One end of the driving block 23 extends to the outside of the installation cavity and is provided with a connecting plate 28. At least two plug rods 29 are provided on one side of the connecting plate 28.

[0042] As a specific technical solution of this embodiment, one end of the insertion rod 29 away from the connecting plate 28 extends to the inside of one of the circular grooves 12, and the end of the insertion rod 29 extending to the inside of the circular groove 12 is tapered. The insertion rod 29 is parallel to the driving block 23. The tapered setting of one end of the insertion rod 29 facilitates the docking of the insertion rod 29 with the circular groove 12.

[0043] As a specific technical solution of this embodiment, buttons 24 are movably provided inside the installation cavity and are located on both sides of the driving block 23. The button 24 extends to the outside of the installation cavity from one side of the driving block 23. The other side of the button 24 and both sides of the driving block 23 are provided with inclined surfaces 25 that fit each other. A stabilizing rod 27 with one end extending to the inside of the driving block 23 is also provided inside the installation cavity.

[0044] A method for using a protective fixture device for lamp processing, comprising the following steps:

[0045] S1. Move the adjusting arm 2, first place the lamp product to be clamped inside the adjusting ring 11, and then select a suitable clamping position according to the shape of the lamp product. First, press the buttons 24 on both sides of the slider 22. The buttons 24 drive the inclined surfaces 25 thereon to contact the inclined surfaces 25 on the driving block 23, so that the driving block 23 stretches the tension spring 26. At the same time, a circle of the driving block 23 translates toward the outside of the installation cavity. During the process, the driving block 23 drives the insertion rod 29 to disengage from the inside of the circular groove 12 through the connecting plate 28, and then the slider 22 can be removed from the adjusting ring 11 or the slider 22 can be directly pushed to slide along the adjusting ring 11 to select the clamping position.

[0046] S2, move the adjusting arm 2 down, after the position of the slider 22 and the adjusting arm 2 is selected, release the button 24, the tension spring 26 resets and pulls the driving block 23, the driving block 23 contacts the inclined surface 25 on the button 24 through the inclined surface 25 thereon, so that the button 24 is reset. During the process, the driving block 23 drives the insertion rod 29 to be inserted into the interior of the circular groove 12 through the connecting plate 28.

[0047] S3, on the movable slide 32, press the pressure plates 314 on both sides of the clamping arm 31, one side of the pressure plate 314 contacts the transmission block 37, and the transmission block 37 compresses the spring 2 372 while driving the inclined block 2 371 to contact the inclined block 1 341, and the inclined block 1 341 is contacted by the inclined block 2 371 and drives the movable block 34 to compress the spring 1 342, and the movable block 34 compresses the spring 1 342 while disengaging from the contact with the limit block 36, at this time, the compression spring on one side of the limit block 36 rebounds and contacts the limit block 36, flips and disengages from the contact with the tooth block 38, and because the tooth block 38 is free from the restriction of the limit block 36, the movable slide 32 slides on the adjusting arm 2 through the clamping arm 31, and the tooth block 38 inside the slide 32 contacts the tooth groove 21 and then retreats.

[0048] S4, move the slide 32 down, when the position of the slide 32 is adjusted, release the pressure plate 314 to disengage from the contact with the transmission block 37, and the spring 2 372 rebounds to drive the transmission block 37 to reset, so that the transmission block 37 drives the inclined block 2 371 to disengage from the contact with the inclined block 1 341. At this time, the spring 1 342 rebounds to contact the inclined block 1 341 and the movable block 34 to reset, and the movable block 34 contacts the two limit blocks 36 again and enters between the two limit blocks 36, so that the two sides of the movable block 34 contact with the straight surfaces 361 of the two limit blocks 36. During the process, one end of the limit block 36 contacts the tooth block 38, so that the tooth block 38 is locked with the tooth groove 21.

[0049] S5. Move the clamping arm 31. After the position of the slide 32 is adjusted, rotate the screw rod 39 to drive the clamping arm 31 to slide on the slide 32. The clamping arm 31 drives the clamping head 311 to contact and clamp the lamp product. During the sliding of the clamping arm 31, the through groove 313 slides on the transmission block 37, so that the pressure plate 314 is always located on one side of the transmission block 37, so that after the relative position between the clamping arm 31 and the slide 32 changes, pressing the pressure plate 314 can still drive the transmission block 37, which greatly increases the convenience of adjustment.

[0050] In summary, in the protective clamp device and method for lamp processing, the adjusting arm 2 can rotate 360 ​​degrees on the adjusting ring 11 to select the clamping position, and the clamp assembly 3 can select the clamping position on the adjusting arm 2, and can be adapted to clamp lamp products of different shapes and sizes, and can effectively avoid the positions where the wall thickness of the lamp product is thinner. The clamping process is safer and there will be no problem of clamping the lamp product, thus meeting the user's needs.

[0051] The protective clamp device and method for lamp processing can remove the adjusting arm 2 from the adjusting ring 11 and select a position and then reinstall it by pressing the button 24, or directly slide on the adjusting ring 11 to select a position, so the operation method is more flexible. The design of the through groove 313 makes the pressure plate 314 always located on one side of the transmission block 37, so that after the relative position between the clamping arm 31 and the slide seat 32 changes, pressing the pressure plate 314 can still drive the transmission block 37, which greatly increases the convenience of adjustment.

[0052] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

10. A method for using the protective fixture device for lamp processing according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Move the adjusting arm (2) and press the buttons (24) on both sides of the slider (22). The buttons (24) drive the inclined surfaces (25) thereon to contact the inclined surfaces (25) on the driving block (23), so that the driving block (23) stretches the tension spring (26). At the same time, a circle of the driving block (23) translates toward the outside of the installation cavity. During the process, the driving block (23) drives the insertion rod (29) to disengage from the inside of the circular groove (12) through the connecting plate (28). Then, the slider (22) can be removed from the adjusting ring (11) or the slider (22) can be directly pushed to slide along the adjusting ring (11) to select a clamping position. S2, after the adjustment arm (2) is moved and the positions of the slider (22) and the adjustment arm (2) are selected, the button (24) is released, and the tension spring (26) is reset to pull the driving block (23), and the driving block (23) contacts the inclined surface (25) on the button (24) through the inclined surface (25) thereon, so that the button (24) is reset. During the process, the driving block (23) drives the insertion rod (29) to be inserted into the inside of the circular groove (12) through the connecting plate (28); S3, the moving slide (32) presses the pressure plates (314) on both sides of the clamping arm (31), one side of the pressure plate (314) contacts the transmission block (37), the transmission block (37) compresses the second spring (372) and drives the second inclined block (371) to contact the first inclined block (341), the first inclined block (341) is contacted by the second inclined block (371) and drives the movable block (34) to compress the first spring (342), the movable block (34) The compression spring (342) is simultaneously disengaged from the contact with the limit block (36). At this time, the compression spring on one side of the limit block (36) rebounds to contact the limit block (36) and flips to disengage from the contact with the tooth block (38). Since the tooth block (38) is disengaged from the restriction of the limit block (36), the slide seat (32) is moved by the clamping arm (31) to slide on the adjustment arm (2), and the tooth block (38) inside the slide seat (32) contacts the tooth groove (21) and then retreats; S4, under the moving slide (32), when the position of the slide (32) is adjusted, the pressure plate (314) is released to disengage from the contact with the transmission block (37), and the spring 2 (372) rebounds to drive the transmission block (37) to reset, so that the transmission block (37) drives the inclined block 2 (371) to disengage from the contact with the inclined block 1 (341). At this time, the spring 1 (342) rebounds to contact the inclined block 1 (341) and the movable block (34) to reset, and the movable block (34) contacts the two limit blocks (36) again and enters between the two limit blocks (36), so that the two sides of the movable block (34) contact with the straight surfaces (361) of the two limit blocks (36). During the process, one end of the limit block (36) contacts the tooth block (38), so that the tooth block (38) is locked with the tooth groove (21); S5. Move the clamping arm (31). After the position of the slide seat (32) is adjusted, rotate the screw rod (39) to drive the clamping arm (31) to slide on the slide seat (32). During the sliding process of the clamping arm (31), the through groove (313) slides on the transmission block (37).
