[0034] It is easy to understand that in other embodiments, the number of column bodies 120 of product 100 includes but is not limited to one, three or five, etc., and the number and position of column body clamp 3 correspond to the number and position of column body 120 of product 100.

[0035] Specifically, as Fig. 2 and Fig. 3As shown, the column clamp 3 comprises a fixing piece 31 and at least two abutting pieces 32, the fixing piece 31 is installed on the base 1, and the fixing piece 31 is provided with a containing groove 33 for containing the column 120, and the at least two abutting pieces 32 are oppositely arranged on both sides of the containing groove 33, the abutting piece 32 is threadedly connected with the fixing piece 31, and can abut against the column 120 through the side wall of the containing groove 33, the at least two abutting pieces 32 apply pressure to the column 120 from opposite directions, and can firmly clamp the column 120, effectively preventing the column 120 from shaking or moving due to stress during processing, ensuring the stability of the column 120 during processing, and thereby improving the processing precision of the product 100; and the position and abutting force of the abutting piece 32 can be adjusted according to the specific size of the column 120, which is beneficial to improve the versatility of the special-shaped product fixing tool; in addition, when clamping the product 100, only the column 120 needs to be placed into the containing groove 33, and then the abutting piece 32 is adjusted for abutting and fixing, which is relatively simple to operate, and the product 100 can be easily taken out from the clamp after the abutting piece 32 is loosened, improving the clamping and dismounting efficiency, saving production time, and helping to improve the overall production efficiency.

[0036] In the embodiment, two abutting pieces 32 are respectively arranged on both sides of the containing groove 33 along the height direction of the fixing piece 31, and the abutting pieces 32 are oppositely arranged correspondingly, thereby increasing the acting point and clamping force on the main body, further ensuring the stability of the column 120, and preventing it from shaking under stress.

[0037] In some optional embodiments, the column clamp 3 can also comprise two clamping blocks oppositely arranged in the horizontal direction, and the two clamping blocks jointly clamp the column 120 to prevent the column 120 from shaking.

[0038] Further, each fixing piece 31 near one side of the product 100 is adapted to the shape of the product 100 and can be fitted to the inner side of the body 110, and the plurality of fixing pieces 31 jointly position the body 110 in the radial direction, thereby further improving the stability of the clamped product 100.

[0039] In the embodiment, the body clamp 2 comprises a first pressing plate 21 and a locking piece 22, one end of the locking piece 22 is threadedly connected with the base 1, and the other end abuts against the first pressing plate 21, so as to press and fix the body 110 on the base 1 through the first pressing plate 21, which has a simple structure and is easy to operate, and the fixing force can be conveniently adjusted by rotating the locking piece 22, so as to realize stable and reliable fixation.

[0040] Further, the first pressing plate 21 is provided with a sliding groove 23 distributed along the length direction of the first pressing plate 21, and the locking member 22 is arranged in the sliding groove 23, so that the operator can flexibly adjust the position of the locking member 22 within the range of the sliding groove 23 according to the specific shape and size of the body 110. For different shapes of the product 100, the locking member 22 can be adjusted to the most suitable position for fixing the product 100, so as to better adapt to the diversity of the product 100, improve the universality and adaptability of the clamp to different products 100, and achieve more stable and reliable fixing effect.

[0041] Due to the application requirement of the product 100 itself, the bottom of the body 110 has a certain inclination, therefore, the special-shaped product fixing tool further comprises a pad 4, the pad 4 is connected to the base 1 and is adapted to the shape of the body 110, and the pad 4 is arranged between the body 110 and the base 1 to make the upper surface of the body 110 parallel to the base 1, so as to ensure that the product 100 is in a relatively horizontal and stable state during processing, facilitating the processing of the cutter on the main body; and the pad 4 is adapted to the shape of the body 110 and can closely fit the bottom contour of the product 100, thereby increasing the contact area between the product 100 and the base 1 and improving the stability of the clamping of the product 100.

[0042] In the embodiment, the number of the pads 4 is at least two, and the at least two pads 4 are symmetrically distributed on both sides of the end of the body 110 with smaller thickness, so as to increase the contact area between the pad 4 and the body 110 and balance the body 110, thereby preventing the center of gravity of the product 100 from deviating and improving the stability of the clamping. Of course, in other embodiments, the number of the pads 4 can also be three, five or six, etc., which is not limited herein.

[0043] Further, the special-shaped product fixing tool further comprises a second pressing plate 5, the second pressing plate 5 is detachably connected with the pad 4, and the second pressing plate 5 and the pad 4 can jointly clamp the product 100 to further fix the body 110.

[0044] As shown in Fig. 1 the column 120 is welded to the body 110, the column 120 comprises a vertical part 121 and a horizontal part 122 connected to each other, the horizontal part 122 is located on the body 110, and the second pressing plate 5 is loaded on the horizontal part 122. On the one hand, due to the change in the thickness distribution of the body 110, the position of the pad 4 corresponds to the position of the column 120, and correspondingly, the position of the second pressing plate 5 corresponds to the position of the horizontal part 122; on the other hand, the connection between the horizontal part 122 and the body 110 has large thickness and high structural strength, which is suitable for clamping and fixing.

[0045] Specifically, the second pressing plate 5 and the pad 4 are threadedly connected by a fastener, which is convenient to install and adjust the clamping force.

[0046] Continuing asFig. 2 and Fig. 3 As shown, the number of body clamps 2 is at least two, and at least two first pressure plates 21 are symmetrically distributed on both sides of the thicker end of the body 110. The first pressure plates 21 and the second pressure plates 5 together achieve the clamping and fixing of the body 110, ensuring the stability of the clamping of the body 110. Of course, in other embodiments, the number of body clamps 2 can also be three, five or six, etc., which is not limited here.

[0047] It should be noted that before processing the column 120, the bottom of the body 110 usually needs to be processed first to obtain the required inclination of the bottom of the product 100. Therefore, the base 1 is provided with clearance holes 11 corresponding to the column 120. The column 120 can be inserted into the corresponding clearance holes 11 so that the body 110 fits against the base 1, thereby fixing the product 100 in reverse so that the tool can process the bottom of the body 110.

[0048] It is easy to understand that since the body 110 and the column 120 are connected by welding, the body 110 will have a certain welding deformation after welding, and its flatness is poor. When the bottom of the body 110 needs to be processed, the traditional clamping method is difficult to achieve stable fixation. In order to solve the above problems, when the column 120 is inserted into the corresponding clearance hole 11, the body 110 is bonded and fixed to the base 1 to achieve reverse fixation of the product 100.

[0049] In this embodiment, AB glue is used to bond the body 110 to the base 1. After the bottom of the body 110 is processed, an adhesive remover is used to dissolve the AB glue to release it from the fixation of the product 100. In other embodiments, phenolic resin glue or polyurethane glue can also be used for bonding, and the corresponding adhesive remover is used to dissolve it. The composition of the adhesive remover is prior art and will not be described in detail here.

[0050] Furthermore, since the column 120 has a certain height, when the column 120 is inserted into the clearance hole 11, the top of the column 120 protrudes beyond the lower surface of the base 1. Therefore, if... Fig. 2 As shown, the fixture for fixing the irregularly shaped product 100 also includes a support leg 6, which is placed under the base 1 to raise the base 1, so that a space is formed under the base 1 to accommodate the column 120, thereby achieving reverse fixing of the product 100 and solving the clamping problem of the irregularly shaped product 100 in this embodiment.

[0051] The fixed part 31, the cushion block 4 and the supporting leg 6 are all connected with the base 1 through fasteners in a threaded mode, facilitating the assembly and disassembly of the special-shaped product fixing tool.

[0052] It should be noted that the abutting part 32, the locking part 22 and the fastener all include but are not limited to bolts or studs, and are not limited herein.

[0053] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
