DETAILED DESCRIPTION

[0024] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0025] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0026] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0027] In the description of this application, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above words in this application based on the specific content of the technical solution.

[0028] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0029] In the embodiment of the present application, the positive direction of the X-axis in the drawings is right, and the negative direction of the X-axis is left; the positive direction of the Y-axis is front, and the negative direction of the Y-axis is back; the positive direction of the Z-axis is up, and the negative direction of the Z-axis is down.

[0030] See also Figure 1 The first embodiment of the present application provides a trimming fine-tuning device 100, which can improve the stability of the trimming machine body 200, and is also conducive to controlling the size adjustment of the trimming, thereby improving processing accuracy and processing efficiency.

[0031] See also Figure 1 and Figure 2 The trimming fine-tuning device 100 includes a rotatable part 110, a fixed part 130 and an adjusting assembly. The rotatable part 110 is rotatably connected to the fixed part 130 to adjust the angle between the rotatable part 110 and the fixed part 130. The rotatable part 110 is also used to connect to the trimmer body 200; the adjusting assembly is connected to the rotatable part 110 and the fixed part 130, and the adjusting assembly is used to maintain the angle between the rotatable part 110 and the fixed part 130.

[0032] Optionally, the trimming blade of the trimmer body 200 is cylindrical, so even if the trimmer body 200 rotates when the rotatable member 110 rotates to drive the trimmer body 200 to move, the trimmer body 200 can continue to perform linear trimming.

[0033] When the trimming fine-tuning device in the embodiment of the present application is used, the fixing member 130 can be used to connect with the workpiece 300 to be processed (for example, see Figure 2 , the side of the fixing part 130 facing away from the rotatable part 110 is in close contact with the workpiece 300 to be processed), thereby preventing the trimmer body 200 from shaking or shifting during use, thereby improving the stability of the trimmer body 200; by adjusting the angle between the rotatable part 110 and the fixing part 130, the distance between the trimmer body 200 and the edge to be processed can be adjusted, thereby achieving precise control of the trimming size, improving the processing accuracy, and eliminating the need for repeated trimming or replacing the workpiece 300 for reprocessing, which can save materials, reduce the frequency of repeated trimming, and improve the processing efficiency of the workpiece 300.

[0034] For example, in combination Figure 2 It can be seen that the larger the angle between the rotatable member 110 and the fixed member 130, the greater the distance between the trimmer body 200 and the edge to be processed, that is, the larger the trimming size; the smaller the angle between the rotatable member 110 and the fixed member 130, the smaller the distance between the trimmer body 200 and the edge to be processed, that is, the smaller the trimming size. Therefore, by adjusting the angle between the rotatable member 110 and the fixed member 130, the trimming size can be adjusted and controlled.

[0035] It should be noted that the trimming size in the embodiments of the present application refers to the trimming thickness of the workpiece 300. For example, after forming the connection groove 310 on the workpiece 300, if it is found that the groove width of the connection groove 310 is slightly smaller than the preset size, the trimming size can be adjusted to fine-tune the groove width of the connection groove 310, thereby appropriately increasing the groove width of the connection groove 310.

[0036] Alternatively, see Figure 1 The rotatable member 110 and the fixed member 130 are slats of the same size. One end of the rotatable member 110 is hinged to one end of the fixed member 130 through a hinge 140, and the adjustment component is arranged at one end of the rotatable member 110 and the fixed member 130 away from the hinge 140.

[0037] Optionally, in some embodiments, the adjustment assembly includes a first connecting member 151, which is fixedly connected to one of the fixed member 130 and the rotatable member 110, and the first connecting member 151 is adjustably connected to the other of the fixed member 130 and the rotatable member 110 and locked with each other to maintain the angle between the rotatable member 110 and the fixed member 130.

[0038] In other words, by fixing the rotatable member 110 or the fixed member 130 at different positions on the first connecting member 151 , the angle formed between the fixed member 130 and the rotatable member 110 can be adjusted.

[0039] Optionally, in some embodiments, the first connecting member 151 is fixedly connected to the fixed member 130, the first connecting member 151 is adjustably connected to the rotatable member 110, and the first connecting member 151 and the rotatable member 110 can be locked to each other. That is, the rotatable member 110 can be fixedly connected to the first connecting member 151 at different positions to form and maintain a predetermined angle between the rotatable member 110 and the fixed member 130.

[0040] Of course, it is also possible that: the first connecting member 151 is fixedly connected to the rotatable member 110, the first connecting member 151 is adjustably connected to the fixed member 130, and the first connecting member 151 and the fixed member 130 can be locked with each other, which will not be elaborated here.

[0041] For example, see Figure 1 and Figure 3 The first connecting member 151 is disposed below the rotatable member 110 and the fixed member 130, and the first connecting member 151 is fixedly connected to the fixed member 130 via a first fastener 1513. Optionally, the first fastener 1513 may be a fastening screw. Of course, the first fastener 1513 may also be a bolt, a pin, or other fasteners, which are not specifically limited herein.

[0042] Alternatively, in some embodiments, see Figure 1 and Figure 3 The adjustment assembly also includes a first adjusting member 1521. A through slot 1511 is provided on the first connecting member 151. The through slot 1511 extends along the rotation direction of the rotatable member 110. The first adjusting member 1521 passes through the through slot 1511 to be detachably connected to the rotatable member 110. The first adjusting member 1521 and the rotatable member 110 press the first connecting member 151 so that the rotatable member 110 and the first connecting member 151 are locked with each other.

[0043] Alternatively, in some embodiments, see Figure 1 and Figure 3 The adjustment component also includes a second adjustment member 1522, which is arranged on a side of the first connecting member 151 away from the fixing member 130, and the second adjustment member 1522 is passed through the first connecting member 151 to be detachably connected to the first adjustment member 1521.

[0044] The second adjusting member 1522 can further limit the first adjusting member 1521 to prevent the first adjusting member 1521 from moving in the through slot 1511 when the first connecting member 151 is locked with the rotatable member 110 .

[0045] Optionally, both the first adjusting member 1521 and the second adjusting member 1522 are adjusting screws. That is, the locking mechanism between the rotatable member 110 and the first connecting member 151 is a threaded connection. Alternatively, the locking mechanism between the rotatable member 110 and the first connecting member 151 can be a snap-fit connection or other connection methods, which are not specifically limited herein.

[0046] Optionally, in some embodiments, the first connecting member 151 has a first surface and a second surface that are adjacent to each other, a through-slot 1511 is defined on the first surface, a through-hole 1512 is defined on the second surface and communicates with the through-slot 1511, and the second adjusting member 1522 is passed through the through-hole 1512 to be detachably connected to the first adjusting member 1521. Providing the through-slot 1511 and the through-hole 1512 on two adjacent surfaces not only makes the structure compact, but also allows the first adjusting member 1521 and the second adjusting member 1522 to be operated without interfering with each other.

[0047] Illustratively, the first connecting member 151 is a rectangular parallelepiped connecting block having a through slot 1511 with upper and lower openings formed therein. The rotatable member 110 is provided with a first threaded hole 111 at the end away from the hinge 140. The first adjusting member 1521 passes through the through slot 1511 to engage with the first threaded hole 111. A through hole 1512 formed on the side of the first connecting member 151 away from the fixed member 130 serves as a second threaded hole. The second adjusting member 1522 engages with the through hole 1512 and passes through the through hole 1512 to abut against the first adjusting member 1521, thereby further limiting the position of the first adjusting member 1521.

[0048] It is understood that when the first adjusting member 1521 passes through the through-slot 1511 to connect with the rotatable member 110, the first connecting member 151 can be pressed against the rotatable member 110 to lock the first connecting member 151 with the rotatable member 110; when the second adjusting member 1522 passes through the first connecting member 151 to abut against the second adjusting member 1522, the first adjusting member 1521 can be limited, thereby preventing the first adjusting member 1521 from moving within the through-slot 1511 when the first connecting member 151 is locked with the rotatable member 110. When the second adjusting member 1522 is separated from the first adjusting member 1521 and the first adjusting member 1521 is loosened, the rotatable member 110 can rotate, and can drive the first adjusting member 1521 to move within the through-slot 1511.

[0049] Optionally, the adjustment assembly may further include a third adjustment member (not shown in the drawings), which is disposed on a side of the first connecting member 151 facing away from the second adjustment member 1522, and is passed through the first connecting member 151 to be detachably connected to the first adjustment member 1521. Optionally, the third adjustment member is the same as the second adjustment member 1522, and is also an adjustment screw, and is also used to limit the first adjustment member 1521.

[0050] It is understandable that the rotation angle range of the rotatable member 110 is limited by the length of the through slot 1511. Since the trimming fine-tuning device 100 in the embodiment of the present application plays a fine-tuning role, the rotation angle range of the rotatable member 110 is not very large, that is, the length of the through slot 1511 is not very large.

[0051] For example, when the rotation angle range of the rotatable member 110 is too small, the through slot 1511 can be approximately a linear through slot; when the rotation angle range of the rotatable member 110 is slightly larger, the through slot 1511 can be an arcuate through slot 1511. The specific shape of the through slot 1511 can be set according to actual needs and is not specifically limited here.

[0052] Optionally, in some embodiments, the adjustment assembly further includes a guide member 1523 , which is disposed on a side of the rotatable member 110 facing away from the fixed member 130 , and is used to guide the second adjustment member 1522 to connect with the first connecting member 151 .

[0053] By providing the guide member 1523 to guide the second adjusting member 1522 to connect with the first connecting member 151, the second adjusting member 1522 can be prevented from being deflected when being connected to or separated from the first connecting member 151 (ie, when the second adjusting member 1522 is tightened or loosened).

[0054] Optionally, the adjustment assembly further includes a second support member 1524. The second support member 1524 is connected to the rotatable member 110 on a side facing away from the fixed member 130. A guide member 1523 is fixed to the side of the second support member 1524 facing away from the rotatable member 110. A groove 15231 is defined on the end of the guide member 1523 proximal to the first connecting member 151. The inner wall of the groove 15231 is threaded. The second adjustment member 1522 engages with the groove 15231 and passes through the groove 15231 to connect to the first connecting member 151. Optionally, the guide member 1523 is a guide plate, the second support member 1524 is a support block, and the groove 15231 is a U-shaped groove. Optionally, the second support member 1524 is fixedly connected to the rotatable member 110 by glue.

[0055] Optionally, in some embodiments, the trimming fine-tuning device further includes a first support member 120 , and the first support member 120 is used to connect the rotatable member 110 and the trimmer body 200 .

[0056] Optionally, in some embodiments, the first support member 120 includes a second connecting member 121 and a third connecting member, the second connecting member 121 is fixedly connected to the rotatable member 110, one end of the third connecting member is movably connected to the second connecting member 121, and the other end of the third connecting member is used to connect to the trimmer body 200.

[0057] For example, see Figure 3 and Figure 4 The second connecting member 121 is a Y-shaped plate, and the third connecting member includes a rectangular plate 1221. The second connecting member 121 has an open end that is fixedly connected to the top of the rotatable member 110. The other end of the second connecting member 121 is provided with a first elongated slot 1211 along its length. The end of the rectangular plate 1221 connected to the second connecting member 121 is provided with a second elongated slot 12211 parallel to the first elongated slot 1211. The first support member 120 also includes a second fastener 123. The second fastener 123 extends through the first elongated slot 1211 and the second elongated slot 12211, respectively, and engages with the first elongated slot 1211 and the second elongated slot 12211 to secure the third connecting member to the second connecting member 121. By using the second fastener 123 to securely connect the first elongated slot 1211 and the second elongated slot 12211 at different locations, the trimmer body 200 can be moved.

[0058] Alternatively, see Figure 4 A vertical plate 1222 is provided at one end of the rectangular plate 1221 away from the second fastener 123, and the trimmer body 200 is connected to the vertical plate 1222 so as to be movable up and down, so that the height of the trimmer body 200 is adjustable.

[0059] For example, the vertical plate 1222 is provided with a third long slot 12221 along the vertical direction, and the first support member 120 further includes a third fastener 124. The third fastener 124 passes through the third long slot 12221 to connect with the trimmer body 200, and the third fastener 124 is engaged with the third long slot 12221. By fixing the trimmer body 200 at different positions of the third long slot 12221 through the third fastener 124, the trimmer body 200 can be moved up and down.

[0060] Optionally, the second fastener 123 and the third fastener 124 are both bolts. Of course, the second fastener 123 and the third fastener 124 may also be other connecting members, which is not specifically limited here.

[0061] Other structures and operations of the trimming and fine-tuning device 100 according to the embodiment of the first aspect of the present application are known to ordinary technicians in this field and will not be described in detail here.

[0062] A second embodiment of the present application provides a trimmer, comprising the trimming fine-tuning device 100 of the first embodiment of the present application, and a trimmer body 200, wherein the trimmer body 200 is connected to the rotatable member 110. For example, the trimmer body 200 is connected to an end of the third connecting member distal from the second fastener 123. Alternatively, the trimmer may be a gong machine.

[0063] For example, the second embodiment of the present application further provides a method for using a trimming machine, for trimming a workpiece 300 having a connecting groove 310. Optionally, the workpiece 300 may be a rectangular plate.

[0064] Exemplarily, the method for using the trimming machine includes the following steps:

[0065] Place the side of the fixing member 130 facing away from the rotatable member 110 in close contact with the side wall of the workpiece 300, move the third connecting member relative to the second connecting member 121 to place the trimmer body 200 in the preset processing position, fix the third connecting member to the second connecting member 121 through the second fastener 123, and then start the trimmer body 200 to trim or groove the connecting groove 310.

[0066] After trimming or grooving, if the width of the connecting groove 310 is found to be slightly smaller than the preset size, the connecting groove 310 cannot be connected to or assembled with other workpieces.

[0067] For example, the second adjusting member 1522 is rotated to separate from the first adjusting member 1521. The first adjusting member 1521 is loosened, and the rotatable member 110 is rotated by a predetermined angle away from the fixed member 130. The predetermined angle can be determined based on the desired width of the connecting groove 310. The first adjusting member 1521 is then tightened, and the second adjusting member 1522 is rotated to abut against the first adjusting member 1521, preventing further rotation of the rotatable member 110. The trimming machine body 200 is then used again to fine-tune the groove width, allowing the trimmed connecting groove 310 to be connected and assembled with other workpieces.

[0068] Other structures and operations of the trimmer according to the embodiment of the second aspect of the present application are known to ordinary technicians in this field and will not be described in detail here.

[0069] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
