Abstract
Description
Technical Field
[0001] The utility model relates to an adjustable groove processing fixture. Background Art
[0002] The electric power construction industry requires a large amount of metal materials during the construction of power stations and power transmission and distribution facilities, which involves the mechanical processing of metal materials. Sawing machines, as a traditional and reliable metal material processing equipment, play an irreplaceable role in the processing of metal materials.
[0003] However, the clamps configured on the sawing machine itself are simple and only rely on the positioning mechanism of the sawing machine for clamping. There are problems such as angle non-adjustability and uneven clamping force. The angle adjustment function in steel plate groove processing cannot be realized, and the angle size and accuracy of the groove are closely related to the welding quality. Utility Model Content
[0004] The purpose of the utility model is to solve the deficiencies of the above prior art and provide an adjustable groove processing fixture.
[0005] An adjustable groove processing fixture includes two fixtures, the fixture includes a mounting plate, a clamping plate, and a connecting plate. The mounting plate is connected to one end of the clamping plate through a hinge structure, one end of the connecting plate is connected to the mounting plate, and the other end is connected to the clamping plate. The connecting plate includes various specifications. The clamping plates of the two fixtures are opposite to each other, and the space between the clamping plates of the two fixtures is used to place the workpiece.
[0006] Working principle: When processing different groove angles, it can be achieved by adjusting the angle between the mounting plate and the clamping plate, and the angle between the mounting plate and the clamping plate is the same as the processed groove angle. After adjustment, the mounting plate and the clamping plate are connected with a connecting plate to fix them to form a triangular structure. During processing, the workpiece is clamped between the two fixtures, and then processed from top to bottom with a cutting knife.
[0007] To facilitate transportation, the hinged structure includes a latch and a connecting column. A through hole matching the size of the latch is provided at the center of the connecting column. The latch is used to connect with the connecting column. The latch and the connecting column are respectively installed on the mounting plate and the splint. The split movable latch structure has the disadvantage of being unstable and is easy to fall off during transportation.
[0008] In order to ensure the installation stability of the latch and the connecting column, the latch and the connecting column are installed on the mounting plate and the connecting plate by welding.
[0009] In order to facilitate the connection of the connecting plate to the mounting plate and the clamping plate, a connecting seat for connecting to the connecting plate is provided on the opposite side of the clamping plate and the mounting plate. The connecting seat includes two parallel fixed plates with spaced intervals, and the two fixed plates are provided with corresponding through holes. The connecting plate is provided with a through hole. The connecting plate is placed between the two fixed plates and connected by a bolt structure.
[0010] Beneficial effect: Compared with the prior art, the utility model can process different groove angles by adjusting the angle between the mounting plate and the clamping plate, and the angle between the mounting plate and the clamping plate is the same as the processed groove angle. After adjustment, the mounting plate and the clamping plate are connected and fixed with a connecting plate to form a triangular structure. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of an adjustable groove processing fixture;
[0012] In the figure, 1, mounting plate, 2, clamping plate, 3, connecting column. DETAILED DESCRIPTION
[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0014] like Figure 1 As shown, the mounting plate 1, the clamping plate 2, and the connecting column 3;
[0015] An adjustable groove processing fixture includes two fixtures, the fixture includes a mounting plate 1, a clamping plate 2, and a connecting plate. The mounting plate 1 is connected to one end of the clamping plate 2 through a hinge structure, one end of the connecting plate is connected to the mounting plate 1, and the other end is connected to the clamping plate 2. The connecting plate includes various specifications. The clamping plates 2 of the two fixtures are opposite to each other, and the clamping plates 2 of the two fixtures are used to place the workpiece.
[0016] In this embodiment, the hinge structure includes a latch and a connecting column 3. A through hole matching the size of the latch is provided at the center of the connecting column 3. The latch is used to be plugged into the connecting column 3. The latch and the connecting column 3 are respectively installed on the mounting plate 1 and the clamping plate 2.
[0017] In this embodiment, the latch pins and the connecting column 3 are mounted on the mounting plate 1 and the connecting plate by welding.
[0018] In this embodiment, a connecting seat for connecting to a connecting plate is provided on the opposite side of the clamping plate 2 and the mounting plate 1. The connecting seat includes two spaced-apart parallel fixing plates, the two fixing plates are provided with corresponding through holes, the connecting plate is provided with through holes, the connecting plate is placed between the two fixing plates, and is connected by a bolt structure.
[0019] Specifically, the fixture uses two standard parts with specifications of 200×180mm, namely mounting plate 1 and clamping plate 2, and the size of the connecting plate is δ=12×60×30mm; a circular hole with a diameter of Φ10mm is processed on the connecting plate by a drilling machine, and then a Φ9.5mm and 30mm long pin is processed on a lathe, and these two processed parts are welded on the back. This fixing pin is then welded to the bottom plate of the fixture 30mm away from the tail end. The connecting plate adopts the rubbing method, and the cutting size is rubbing on the fixture with the actual measured angle to ensure that the connecting plate can be processed as accurately as possible. After processing, drilling is performed according to the rubbing hole position;
[0020] The fixing plate is processed by sawing machine, and the connecting seat is composed of two pieces of δ12mm steel plate with sizes of 30×30mm and 30×60mm. The larger size is the bottom plate, and the smaller size is processed by drilling machine to process 13mm holes, welded with 12mm, 8.8 grade high-strength bolts, and then welded the upper pressure plate and the bottom plate to the clamping surface, and the connecting plate 2 is pressed with bolts. This connection method is more convenient for replacement.
[0021] like Figure 1 As shown in the figure, the groove of the steel plate to be processed is α. According to the principle of parallel angles, ∠α is equal to ∠β1. Because ∠β1+∠β2 is equal to 90°, and ∠β2+∠β is equal to 90°, it can be deduced that ∠β1 is equal to ∠β, so ∠β is equal to ∠α, that is, the opening angle of the fixture is equal to the groove angle of the steel plate to be processed.
[0022] According to the above reasoning, if you want the steel plate groove processing angle to be as wide as possible, you must increase the opening width of the clamp as much as possible. Considering the processing width of the sawing machine's worktable, the working angle range of this clamp is designed to be: 10° to 45°.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
