Multi-workpiece clamping device for milling inclined planes

Abstract

The invention discloses a multi-workpiece clamping device for milling inclined planes. The multi-workpiece clamping device comprises a first fixing plate, a second fixing plate, a clamp plate and an abutting assembly, wherein the first fixing plate and the second fixing plate are oppositely arranged. When a diagonal plane on a workpiece needs to be machined, the clamping device is clamped on the vice.

The first fixing plate and the containing groove are used for accurately positioning the workpiece, and the avoiding hole can prevent the cylindrical part from being deformed due to clamping force. When the second fixing plate gets close to the first fixing plate, the abutting assembly and the first fixing plate of the step can clamp the workpiece. The clamping device is simple in structure and low in manufacturing cost, machining of a plurality of workpieces can be achieved only through the vice, efficiency is greatly improved, the frequency of an operator for frequently assembling and disassembling the workpieces is reduced, and the labor intensity of the operator is relieved.

DETAILED DESCRIPTION

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the "upper" and "lower" of the corresponding parts in the use state relative to the direction of gravity, and "inside" and "outside" refer to the "inside" and "outside" relative to the corresponding parts' own contours. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements.

[0033] refer to Figure 1 and Figure 2 As shown, the workpiece 1 includes a cuboid portion 11 and a cylindrical portion 12 arranged on one end face of the cuboid portion 11 . The workpiece 1 needs to be machined with a chamfer 13 on an edge of the cuboid portion 11 parallel to the central axis of the cylindrical portion 12 .

[0034] According to the embodiments of the present application, reference Figures 3 to 9 As shown, a multi-piece workpiece clamping device for milling inclined surfaces is provided, comprising: a first fixing plate 2 and a second fixing plate 3 that are arranged opposite to each other, a fixture plate 4 and an abutting assembly 5.

[0035] refer to Figure 3 and Figure 4 As shown, the first fixing plate 2 is provided with at least one clearance hole 21 matching the cylindrical portion 12, and the clearance hole 21 is used to insert the cylindrical portion 12 of the workpiece 1 to prevent the cylindrical portion 12 from being deformed by the clamping force; the clamping plate 4 is fixedly connected to the side of the first fixing plate 2 facing the second fixing plate 3, and has at least one accommodating groove 41 for positioning the rectangular portion 11, and the number of the accommodating grooves 41 is equal to the number of the clearance holes 21, and the first fixing plate 2 and the accommodating groove 41 are used to position the workpiece so that the chamfered surface 13 to be processed of the workpiece 1 is horizontal without the need for alignment; the second fixing plate 3 is provided with a push-up assembly 5 on the side facing the first fixing plate 2, and the push-up assembly 5 is used to push against one end of the workpiece 1 facing the second fixing plate 3, and when the first fixing plate 2 and the second fixing plate 3 are close to each other, the workpiece 1 is fixed.

[0036] In the above embodiment, when the chamfered surface 13 on the workpiece 1 needs to be processed, the clamping device can be clamped on the vise. Since the fixture plate 4 is provided with a receiving groove 41 for positioning the workpiece 1, the receiving groove 41 can make the chamfered surface 13 to be processed horizontal after the workpiece 1 is placed on it, so as to facilitate the milling cutter of the milling machine to process the chamfered surface 13. The receiving groove 41 can be calculated according to the position of the chamfered surface 13 of the workpiece 1 and the angle between the side of the cuboid portion 11, so that the chamfered surface 13 is finally in a horizontal state, and the clearance hole 21 on the first fixed plate 2 can facilitate the insertion of the cylindrical portion 12 of the workpiece 1. The receiving groove 41, the first fixed plate 2 and the clearance hole 21 can accurately position the workpiece 1. There is a step between the cylindrical portion 12 and the cuboid portion 11, and the step surface serves as the positioning surface of the workpiece 1 in the clamping direction. When the second fixed plate 3 approaches the first fixed plate 2, the abutting assembly 5 installed on the second fixed plate 3 and the step can clamp the workpiece 1. Thereby, the workpiece 1 is positioned and clamped, which is convenient for the milling cutter to process the chamfered surface 13. Since the fixture plate 4 can be provided with a plurality of accommodating grooves 41, and the first fixed plate 2 can be provided with a number of clearance holes 21 equal to the number of accommodating grooves 41, the clamping device can process multiple workpieces at the same time. The clamping device of the present application has a simple structure and a low manufacturing cost. As long as there is a vise, multiple workpieces can be processed, which greatly improves efficiency, reduces the frequency of frequent loading and unloading of workpieces by operators, and reduces the labor intensity of operators.

[0037] According to the embodiments of the present application, reference Figure 7 As shown, the included angle between the chamfered surface 13 of the workpiece and one side surface of the cuboid portion 11 is set to ∠α, and accordingly, each of the accommodating grooves 41 also needs to be inclined, and the included angle between the bottom surface of the accommodating groove 41 and the horizontal plane is ∠α. When the included angle between the bottom surface of the accommodating groove 41 and the horizontal plane is ∠α, the included angle between the chamfered surface 13 to be processed on the workpiece 1 and the horizontal plane is 0°. This achieves the positioning of the workpiece 1, making it easier for the milling cutter to process the chamfered surface 13 in the horizontal direction.

[0038] According to the embodiments of the present application, reference Figure 4 As shown, the number of the accommodating grooves 41 may be two.

[0039] Since it takes multiple processes to transform workpiece 1 into workpiece 2, the size of each workpiece 1 is not very precise and uniform. When there is a size error between two workpieces 1 clamped at the same time, the clamping degree of workpiece 1 may be inconsistent, with some clamped tightly and some clamped loosely. To prevent this from happening, refer to Figure 4 , Figure 6 and Figure 8As shown, the abutting assembly 5 may include a U-shaped abutting member 51, the U-shaped abutting member 51 includes two parallel abutting arms 511 and a connecting portion 512 connecting the two abutting arms 511, the connecting portion 512 is provided with a vertical first through hole 513, and the U-shaped abutting member 51 is horizontally hinged to the side of the second fixing plate 3 facing the first fixing plate 2 through a first pin 52. With such a design, the U-shaped abutting member 51 is equivalent to being movably arranged on the second fixing plate 3, that is, it can swing in a horizontal plane, and when the second fixing plate 3 approaches the first fixing plate 2 and clamps the two workpieces 1, the U-shaped abutting member 51 can adaptively rotate around the first pin 52, so that the two workpieces 1 can be clamped at the same time.

[0040] According to the embodiments of the present application, reference Figure 4 As shown, in order to further improve the clamping efficiency and enable the clamping device to clamp more workpieces 1, the number of the receiving grooves 41 is four, and every two of the receiving grooves 41 form a group of receiving grooves 41; the two groups of receiving grooves 41 are arranged in the horizontal direction.

[0041] refer to Figure 6 and Figure 8 As shown, the abutting assembly 5 includes two U-shaped abutting members 51 and a floating frame 53. The U-shaped abutting member 51 includes two parallel abutting arms 511 and a connecting portion 512 connecting the two abutting arms 511. The connecting portion 512 is provided with a vertical first through hole 513.

[0042] refer to Fig. 9 As shown, the floating frame 53 has two accommodating chambers 531 arranged in the horizontal direction, and the middle part of each accommodating chamber 531 has a vertical second through hole 532. Each U-shaped abutting member 51 is hinged in one accommodating chamber 531 of the floating frame 53 through a first pin 52; the floating frame 53 located between the two accommodating chambers 531 has a vertical third through hole 533, and the floating frame 53 is hinged on the side of the second fixed plate 3 facing the first fixed plate 2 through a second pin 54. In the above embodiment, the floating frame 53 is movably mounted on the second fixed plate 3 through the second pin 54, that is, the floating frame 53 can swing in the horizontal plane, so that the two U-shaped abutting members 51 can adapt to each other in the horizontal plane, and each U-shaped abutting member 51 can also rotate and adapt to each other in the horizontal plane. Therefore, four workpieces 1 can be clamped simultaneously through the floating frame 53 and the two U-shaped abutting members 51, thereby improving the processing efficiency.

[0043] It should be noted that in this application, two workpieces 1 are required to implement one adaptive clamping, and only the U-shaped abutment 51 can be used, so the number of workpieces 1 should be a multiple of 2. If two adaptive clampings need to be implemented, the floating frame 53 needs to be used, and the number of workpieces 1 is a multiple of 4. This application does not limit this.

[0044] According to the embodiments of the present application, reference Fig. 9 As shown, the floating frame 53 is an I-shaped frame plate structure, including an upper plate 534, a lower plate 535, and a connecting plate 536 connected between the upper plate 534 and the lower plate 535, and the connecting plate 536 divides the space between the upper plate 534 and the lower plate 535 into two accommodating chambers 531. In other embodiments, the floating frame 53 can also be in other forms, which is not limited in the present application.

[0045] According to the embodiments of the present application, reference Figure 4 and Figure 6 As shown, the second fixing plate 3 has a rectangular frame 31 on the side facing the first fixing plate 2 , and fourth through holes 32 are provided on the top plate and the bottom plate of the rectangular frame 31 . The floating frame 53 is hinged in the rectangular frame 31 through a second pin 54 .

[0046] According to the embodiments of the present application, reference Figure 7 As shown, the two receiving grooves 41 of the same group are connected to each other. Such a design can eliminate the need for partitions between the receiving grooves 41 and can also reduce the overall size of the clamping device.

[0047] The vise includes a fixed jaw body and a movable jaw body, both of which are provided with jaw mounting holes, and both of which are connected with jaw plates by bolts; a first mounting hole 22 is provided on the first fixed plate 2, and the first mounting hole 22 is used to mount the first fixed plate 2 to the fixed jaw body by bolts; a second mounting hole 33 is provided on the second fixed plate 3, and the second mounting hole 33 is used to mount the second fixed plate 3 to the movable jaw body by bolts.

[0048] In this way, when using, the bolts of the two jaw plates of the vise are removed, and the two jaw plates that come with the vise are taken down, and a new vise mouth is formed with the first fixing plate 2 and the second fixing plate 3 of the embodiment of the present application, and the first fixing plate 2 is fixed by using the original bolt hole position on the vise and the first mounting hole 22 on the first fixing plate 2, and the second fixing plate 3 is fixed by using the original bolt hole position on the vise and the second mounting hole 33 of the second fixing plate 3, so that the multi-piece workpiece clamping device for milling inclined surfaces is clamped on the vise, thereby realizing one-time clamping and multiple uses, reducing the number of clamping times and improving processing efficiency.

[0049] The following is a description of the implementation principle of this application using a specific processing process:

[0050] Step 1: Remove the two jaw plates of the vise, fix the first fixing plate 2 by using the original bolt hole position on the vise and the first mounting hole 22 on the first fixing plate 2, fix the second fixing plate 3 by using the original bolt hole position on the vise and the second mounting hole 33 of the second fixing plate 3, and clamp the multi-piece workpiece clamping device for milling the inclined surface on the vise;

[0051] Step 2: Take four workpieces 1, insert the rectangular parallelepiped of each workpiece 1 along the receiving groove 41, and insert the cylindrical portion 12 into the clearance hole 21 of the first fixing plate 2 until the rectangular parallelepiped portion 11 contacts the first fixing plate 2. In this clamping position, the milling cutter can process a horizontal chamfered surface 13;

[0052] Step 3: Shake the vise handle to make the movable jaw bring the second fixed plate 3 closer to the first fixed plate 2 until the abutting arms 511 of the U-shaped abutting member 51 on the second fixed plate 3 abut against the four workpieces 1, and continue to rotate the vise handle to make the vise apply a certain pre-tightening force to the workpiece 1 to achieve clamping;

[0053] Step 4: Start the milling machine to move the tool and process the chamfered surface 13.
