[0014] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0018] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0019] Please see Figure 1 The clamping and fixing device provided by this utility model includes a main body 1, a support block 3 and a pressing block component 2. The support block 3 is assembled on the main body 1, and the pressing block component 2 is assembled on the main body 1. It is used to clamp the workpiece to be processed when rotated to a suitable position to cooperate with the support block 3.

[0020] It is known that the main body 1 can be fixed on the bracket. When processing some automotive parts, such as the front hood side panel, door side panel and front hood, the workpiece is attached to the support block 3, and then the clamping block component 2 is rotated so that the clamping block component 2 is in close contact with the workpiece. Then, the clamping block component 2 is fixed at the clamping position so that the clamping block component 2 and the support block 3 cooperate to clamp the workpiece.

[0021] Please continue reading. Figure 1 In some embodiments, the clamping block component 2 includes a clamping handle 201, a hinge shaft 203, and a locking pin 202. Correspondingly, the main body 1 has an insertion groove. One end of the clamping handle 201 is inserted into the insertion groove and hinged to the main body 1 through the hinge shaft 203. The locking pin 202 is connected to the main body 1 and locked to the clamping handle 201 to fix the clamping handle 201.

[0022] It can be seen that in the initial state, the clamping handle 201 is in the active state. When it is necessary to clamp the workpiece, the clamping handle 201 is rotated to the position close to the workpiece, and then the position of the clamping handle 201 is locked by the locking pin 202. The clamping handle 201, together with the support block 3, clamps the workpiece. The clamping block component 2 of this structure is simple in structure and easy to operate.

[0023] Please see Figure 2In some embodiments, the clamping handle 201 includes a hinge section 201c, an extension section 201b, and a clamping section 201a. The extension section 201b connects the hinge section 201c and the clamping section 201a to form a U-shape. The hinge section 201c has a hinge hole 201e and a locking hole 201d. The hinge section 201c is inserted into the insertion groove. The hinge shaft 203 passes through the hinge hole 201e and is connected to the main body 1. The locking pin 202 is connected to the main body 1 and passes through the locking hole 201d. The clamping section 201a includes a clamping surface, a connecting surface, an upper end surface, and a side end surface. The clamping surface, connecting surface, upper end surface, and side end surface are connected end to end in sequence to form the clamping section 201a. The clamping surface is arc-shaped and is positioned opposite to the support block 3.

[0024] It is known that the arc-shaped surface contacts the workpiece, thereby reducing damage to the workpiece. When the arc-shaped surface is in the clamping state, the clamping surface and the support block 3 are positioned relative to each other, which can be understood as the clamping surface being located directly above the support block 3.

[0025] Please see Figure 1 In some embodiments, the main body 1 includes a main body 101, a base plate 104, an adjusting plate 103 and an adjusting bolt 102. The adjusting plate 103 is disposed on the main body 101, and the adjusting bolt 103 is threadedly connected to the adjusting plate 103 and the base plate 104.

[0026] It is understood that the main body 101 can be rectangular, and the base plate 104 can be an integral structure with the main body 101. The base plate 104 can be connected and fixed to the bracket by bolts. A pad can also be set under the base plate 104. The bolts pass through the base plate 104 and the pad to connect and fix to the bracket. In the initial state, the main body 101 can be movably placed on the base plate 104. Then, the bolt 102, threaded adjustment plate 103, and base plate 104 are adjusted to achieve a fixed connection between the main body 101 and the base plate 104. The height of the main body can be adjusted by adjusting the relative position between the adjustment plate 103 and the adjustment bolt 103.

[0027] Please see Figure 1 In some embodiments, the support block 3 includes a support block body 301, a zero-position pin 303, and a positioning pin 302. Correspondingly, an assembly cavity is provided in the main body 1. The support block body 301 passes through the assembly cavity. The zero-position pin 303 is threadedly connected to the main body 1 and passes through the assembly cavity. The zero-position pin 303 supports the support block body 301. The positioning pin 302 is threadedly connected to the main body 1 and passes through the assembly cavity to abut against the support block body 301 to limit the height of the support block body 301.

[0028] It is known that the zero-position pin 303 penetrates into the bottom of the assembly cavity, which is located inside the main body 101. The lower end of the support block body 301 abuts against the zero-position pin 303, which supports the support block body 301, thereby placing the support block body 301 in a zero-position state. This state is the most basic height position of the support block body 301. This basic position is for some special automotive parts. When there is a certain deviation in this basic position, the height of the support block body 301 can be adjusted by the positioning pin 302 to meet the requirements of the basic position.

[0029] As can be seen from the above description, the clamping and fixing device provided by this utility model, through the cooperation of the support block 3 and the pressing block component 2, can clamp and fix the workpiece to be processed, improve the stability of the workpiece during the processing, and the fixing method is simple and convenient.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
