Description
Technical Field
[0001] This utility model belongs to the field of tooling and fixtures, and in particular relates to a vise with rotatable jaws. Background Technology
[0002] Currently, using a vise to clamp irregularly shaped workpieces requires installing aluminum blocks into the jaws of a standard vise. The workpiece-shaped jaws are then milled into these aluminum blocks. This method uses a pair of aluminum blocks to create only one type of jaw, resulting in high material consumption, cumbersome jaw replacement, and poor repositioning accuracy after disassembly. This negatively impacts product quality and work efficiency. Utility Model Content
[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a vise with a simple structure and multiple functions and a rotatable jaw.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A vise with rotatable jaws includes a sliding base, a fixed base, a base, a linear drive, and two rotating disks. The base is horizontally arranged, the fixed base is fixedly arranged on the base, and the sliding base is slidably arranged on the base. Both rotating disks are horizontally arranged, and the two rotating disks are a first rotating disk and a second rotating disk, respectively. The first rotating disk is coaxially rotatably mounted on the upper end of the fixed base, and the second rotating disk is coaxially rotatably mounted on the upper end of the sliding base. Notches are provided at the edges of the two rotating disks. The linear drive is mounted on the base, and its driving end is connected to the sliding base for transmission. The linear drive is used to drive the sliding base to move closer to or further away from the fixed base.
[0005] The beneficial effects of the above technical solution are as follows: the sliding seat can slide close to the fixed seat, so that the notches and slots on the two rotating disks are aligned with each other to clamp the workpiece. When the sliding seat slides away from the fixed seat, the two rotating disks move away from each other to release the workpiece. At the same time, the rotating disks can be flexibly rotated to switch different notch and slot alignments to clamp different workpieces.
[0006] The rotating disk described in the above technical solution is a regular polygon, and a notch is provided on each side of its upper edge.
[0007] The beneficial effects of the above technical solution are that it simplifies the structure and allows the two rotating disks to be mutually restrained when aligned on any side to prevent them from rotating.
[0008] The upper surface of the rotating disk in the above technical solution is a regular polygon with at least three sides.
[0009] The beneficial effect of the above technical solution is that it enables the two rotating disks to clamp at least three sizes of workpieces.
[0010] The notches and / or grooves on each side of the rotating disk in the above technical solution have different shapes and / or sizes.
[0011] The beneficial effect of the above technical solution is that it enables the vise to adapt to the clamping needs of workpieces of different shapes or the same shape but different sizes.
[0012] The linear drive component described in the above technical solution is a telescopic cylinder or a linear module.
[0013] The advantages of the above technical solution are that it has a simple structure and is easy to use.
[0014] The linear drive component described in the above technical solution includes a drive rod. The sliding seat is provided with a threaded hole that extends through the left and right sides. The middle part of the drive rod is provided with an external thread that mates with the threaded hole. The drive rod passes through the threaded hole and is threadedly connected to the threaded hole. One end of the drive rod near the fixed seat is rotatably connected to the fixed seat. The other end of the drive rod is provided with a handle. Rotating the drive rod clockwise or counterclockwise drives the sliding seat to move closer to or further away from the fixed seat.
[0015] The beneficial effect of the above technical solution is that it allows the linear drive component to be adjusted manually, making it convenient to use.
[0016] In the above technical solution, the upper end of the fixed base is recessed with a first blind hole, and the first rotating disk is provided with a plurality of first through holes that pass through vertically at intervals around it. The first rotating disk can be rotated until any one of the first through holes is aligned with the first blind hole, and a first pin is inserted to limit the first rotating disk on the fixed base.
[0017] The beneficial effect of the above technical solution is that the first rotating disk can be limited on the fixed seat to prevent it from shaking after clamping the workpiece.
[0018] In the above technical solution, the upper end of the sliding seat is recessed with a second blind hole, and the second rotating disk is provided with a plurality of second through holes that pass through vertically at intervals in the circumferential direction.

[0022] The lower end of the base described in the above technical solution is provided with an anti-slip pad.
[0023] The beneficial effect of the above technical solution is that it can prevent the vise from slipping when placed on the carrier. Attached Figure Description

Detailed Implementation
[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0030] like Figures 1-4As shown, this embodiment provides a vise with rotatable jaws, including a sliding base 1, a fixed base 2, a base 3, a linear drive 4, and two rotating disks 5. The base 3 is horizontally arranged, the fixed base 2 is fixedly arranged on the base 3, and the sliding base 1 is slidably arranged on the base 3. The two rotating disks 5 are both horizontally arranged, namely a first rotating disk 5a and a second rotating disk 5b. The first rotating disk 5a is coaxially rotatably mounted on the upper end of the fixed base 2, and the second rotating disk 5b is coaxially rotatably mounted on the upper end of the sliding base 1. The two rotating disks 5 are provided with notches and slots 51 at their edges. The linear drive 4 is mounted on the base 3 and its drive end is connected to the sliding seat 1. The linear drive 4 is used to drive the sliding seat 1 to move closer to or away from the fixed seat 2. This allows the sliding seat to slide closer to the fixed seat, so that the notches and slots on the two rotating disks are aligned with each other to clamp the workpiece. When the sliding seat slides away from the fixed seat, the two rotating disks move away from each other to release the workpiece. At the same time, the rotating disks can be flexibly rotated to switch different notch and slot alignments to clamp different workpieces.
[0031] In this embodiment, both the fixed seat and the sliding seat can be cuboid or cylindrical.
[0032] In this embodiment, the middle part of the rotating disk can be rotatably connected to the upper end of the fixed seat or the sliding seat.
[0033] like Figure 1 and Figure 2 As shown, the rotating disk 5 in the above technical solution is a regular polygon, and a notch 51 is provided on each side edge of its upper end, which makes its structure simple, and the two rotating disks can limit each other to avoid rotation when the two sides are aligned.
[0034] In the above technical solution, the upper surface of the rotating disk 5 is a regular polygon with at least three sides, so that the two rotating disks can clamp at least three sizes of workpieces. Preferably, the rotating disk is cylindrical, and its upper surface can be an equilateral triangle, square, regular pentagon, regular hexagon, regular heptagon, regular octagon, regular nonagon, regular decagon, regular unelectra, or regular dodecagon.
[0035] like Figure 1 and Figure 2 As shown, the notches and / or slots 51 on each side of the rotating disk 5 in the above technical solution have different shapes and / or sizes, thus enabling the vise to adapt to the clamping needs of workpieces of different shapes or the same shape but different sizes. The shape and size of each notch and slot are specifically determined according to the shape and size of the workpiece.
[0036] The linear drive component 4 described in the above technical solution is a telescopic cylinder (telescopic air cylinder, hydraulic cylinder, or telescopic electric cylinder) or a linear module (such as an electric linear module), which has a simple structure and is easy to use; preferably, such as Figure 2 As shown, the linear drive 4 includes a drive rod 41. The sliding seat 1 is provided with a threaded hole 11 that extends through the left and right sides. The middle part of the drive rod 41 is provided with an external thread that mates with the threaded hole 11. The drive rod 41 passes through the threaded hole 11 and is threadedly connected to the threaded hole 11. One end of the drive rod 41 near the fixed seat 2 is rotatably connected to the fixed seat 2. The other end of the drive rod 41 is provided with a handle 42. Rotating the drive rod 41 clockwise or counterclockwise drives the sliding seat 1 to move closer to or further away from the fixed seat 2. This allows the linear drive to be adjusted manually, making it convenient to use.
[0037] like Figure 3 As shown, in the above technical solution, the upper end of the fixed base 2 is recessed with a first blind hole 21, and the first rotating disk 5a is provided with a plurality of first through holes 52 arranged circumferentially. The first rotating disk 5a can be rotated until any one of the first through holes 52 is aligned with the first blind hole 21, and a first pin 53 is inserted to limit the first rotating disk 5a on the fixed base 2. This allows the first rotating disk to be limited on the fixed base to prevent it from shaking after clamping the workpiece. In this embodiment, the number of first through holes can be the same as the number of sides on the upper surface of the first rotating disk, and the plurality of first through holes are distributed on a circle with the center of the first rotating disk as the center. When any one of the first through holes is aligned with the first blind hole, the side of the first rotating disk near the second rotating disk is exactly perpendicular to the length direction of the base.
[0038] like Figure 4 As shown, in the above technical solution, the upper end of the sliding seat 1 is recessed with a second blind hole 12, and the second rotating disk 5b is provided with a plurality of second through holes 54 arranged circumferentially. The second rotating disk 5b can be rotated until any one of the second through holes 54 is aligned with the second blind hole 12, and a second pin 55 is inserted to limit the second rotating disk 5b on the sliding seat 1. This allows the second rotating disk to be limited on the sliding seat to prevent it from shaking after clamping the workpiece. Similarly, the distribution of the second through holes on the second rotating disk can be referenced to the distribution of the first through holes on the first rotating disk.
[0039] like Figure 4As shown, in the above technical solution, the upper end of the base 3 is provided with a T-shaped groove 31 along the left and right direction, and the lower end of the sliding seat 1 is provided with a sliding tooth 13 that extends into the groove 31 (which belongs to the prior art and will not be described in detail here). This allows the sliding seat to slide conveniently on the base, while also having good load-bearing characteristics.
[0040] like Figure 4 As shown, the lower end of the base 3 in the above technical solution is provided with an anti-slip pad 32, which can prevent the vise from slipping when placed on the carrier.
[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
