Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 to 5, the clamp of the present invention includes a driving member 100, a first positioning plate 200, a first elastic member 300, a plurality of clamping plates 400, and a base 500; the plurality of clamping plates 400 are arranged perpendicular to the first plane and the plurality of clamping plates 400 are parallel to each other; the first elastic member 300 is disposed between two adjacent clamping plates 400, and the first elastic member 300 (e.g., a spring or other elastic force expansion and contraction component) is configured to bias the two adjacent clamping plates 400 away from each other; the driving member 100 is connected to the clamping plates 400 at the end, and may be a cylinder or an oil cylinder or other power form, and the driving member 100 is configured to drive the two adjacent clamping plates 400 to approach each other against the elastic force of the first elastic member 300 to clamp the workpiece 900 between the two adjacent clamping plates 400; the first positioning plate 200 is disposed perpendicular to the first plane and the first positioning plate 200 is perpendicular to the clamping plate 400, the first positioning plate 200 is disposed as follows: at least a part of the workpiece 900 having one end abutting on the first retainer plate 200 can be interposed between the adjacent two clamp plates 400.

In the present invention, in the initial state, the driving member 100 does not drive the clamping plates 400, and the plurality of clamping plates 400 are released by the elastic force of the first elastic member 300, that is, the two adjacent clamping plates 400 are biased toward the direction away from each other to form a distance between the two clamping plates 400 enough to place the workpiece 900. The plurality of workpieces 900 are respectively placed between the clamping plates 400, and one ends of the plurality of workpieces 900 are abutted against the first positioning plate 200, so that the end parts of the plurality of workpieces 900 are flush, the plurality of workpieces 900 are accurately positioned, and subsequent processing work is facilitated. The driving member 100 is controlled to drive the clamping plates 400 to move, so that two adjacent clamping plates 400 are close to each other by overcoming the elastic force of the first elastic member 300, and the workpiece 900 is clamped, so that a plurality of workpieces can be clamped and positioned simultaneously, and the machining efficiency of the machine tool is improved.

In order to be able to adapt as much as possible to a plurality of machining situations and workpieces 900 of various sizes, the clamping apparatus is optionally arranged to allow the width of the workpiece 900 to be greater than the width of the clamping plate 400, it being explained here that the width of the clamping plate 400 is perpendicular to the direction of movement of the clamping plate 400 and parallel to the first plane. That is, even if the width of the workpiece 900 is greater than the width of the clamping plate 400, the two ends of the workpiece 900 can be extended outwards from the two ends of the clamping plate 400, as shown in fig. 1, the clamping plate 400 can still effectively clamp the workpiece 900, therefore, the size of the clamping plate 400 does not need to be changed for adapting to workpieces 900 with different sizes, thereby effectively enhancing the application range of the clamp of the present invention.

It should be understood that the clamp may be enabled in various ways to allow the width of the workpiece 900 to be larger than the width of the clamping plate 400, for example, the clamping plate 400 has a height high enough that the first elastic member 300 is disposed on the upper portion of the clamping plate 400 so as not to interfere with the placement of the workpiece 900 in the width direction. In order to prevent the clamp plates 400 from being too large and allow the width of the workpiece 900 to be larger than the width of the clamp plates 400, optionally, the top surface of the base 500 of the clamp is parallel to the first plane, the top surface is provided with a groove 510, the first elastic member 300 is arranged in the groove 510, the plurality of clamp plates 400 are arranged along the length direction of the groove 510, the lower portion of the clamp plate 400 is arranged in the groove 510, the upper portion of the clamp plate 400 extends out of the groove 510, and the width of the notch of the groove 510 is smaller than the width of the workpiece 900. In other words, the first elastic member 300 is hidden under the top surface of the base 500, and the workpiece 900 is placed on the top surface of the base 500, so that the first elastic member 300 is disposed without any interference with the workpiece 900. Also, in order to prevent the workpiece 900 from inadvertently falling into the groove 510, the width of the notch of the groove 510 is set to be smaller than the width of the workpiece 900, so that the workpiece 900 can be prevented from falling into the groove 510.

As shown in fig. 5, in an embodiment of the present invention, the notch includes two baffles 520 respectively disposed at opposite sides of the groove 510, and a separation distance between the two baffles 520 is smaller than a width of the workpiece 900. That is, the longitudinal section of the groove 510 is formed in a rectangular shape having an opening at the center of the top, and the width of the opening is the interval between the two baffles 520, thereby forming the above-mentioned notch. The baffle 520 provides support to the workpiece 900 and, to enable the baffle 520 to achieve greater structural strength, the baffle 520 may be integrally formed on the sidewalls of the recess 510.

In the above embodiment, the width of the groove bottom of the groove 510 is greater than the width of the notch of the groove 510, that is, the width of the groove bottom of the groove 510 is greater than the spacing distance between the two baffles 520, in which case, the clamping of the workpiece 900 can be achieved as long as the upper portion of the clamping plate 400 can protrude out of the notch, in order to provide better structural strength and more cost saving to the clamping plate 400, it is preferable that the clamping plate 400 be configured such that the upper portion thereof has a width matching the notch and the lower portion thereof has a width matching the groove bottom of the groove 510, in other words, the clamping plate 400 be formed in an inverted T-shaped configuration in longitudinal section, and the lower portion of the clamping plate 400 can obtain better support since it has a sufficient width to fit the groove bottom of the groove 510, while the upper portion of the clamping plate 400 is only the same as the width of the notch.

In order to position the workpiece 900 with a larger width, optionally, the base 500 is provided with a first elongated hole 530, an extending direction of the first elongated hole 530 is perpendicular to an extending direction of the groove 510, and the first positioning plate 200 can move along the first elongated hole 530 by a fastener (not shown in the figure) to adjust a distance between the first positioning plate and the clamping plate 400. Of course, the first positioning plate 200 can be moved manually, or the first positioning plate 200 can be driven by a cylinder or an oil cylinder, etc., which is not limited by the present invention.

In order to make the one end of work piece 900 only lean on to lean on the laminating on first locating plate 200 and can not produce the clearance, can directly promote work piece 900 through manual mode and tightly lean on first locating plate 200, and in the utility model discloses an embodiment, for more effectively, neatly promote a plurality of work pieces 900 simultaneously all to lean on first locating plate 200, anchor clamps include second locating plate 600, second locating plate 600 perpendicular to first plane setting and be parallel to each other with first locating plate 200, second locating plate 600 sets up to pushing work piece 900 and leaning on first locating plate 200.

It should be understood that the second positioning plate 600 can be directly driven by a manual, pneumatic, hydraulic, electric cylinder, etc. in order to ensure that the second positioning plate 600 moves according to the predetermined moving track, optionally, the base 500 is provided with a second elongated hole 540, the extending direction of the second elongated hole 540 is perpendicular to the extending direction of the groove 510, and the second positioning plate 600 can move along the second elongated hole 540 by a fastening member (not shown in the figure) to adjust the distance between the second positioning plate 600 and the clamping plate 400. The predetermined moving track is the length direction of the second elongated hole 540.

If the automatic driving device is used to drive the second positioning plate 600 to move, the second positioning plate 600 may move too much, so that the pressing force for pushing the workpiece 900 to abut against the first positioning plate 200 is too large, which may cause damage to the second positioning plate 600, the workpiece 900, and the first positioning plate 200. In order to avoid the above problem, the fixture may optionally include a second elastic member 700 and a third positioning plate 800, the second elastic member 700 may be a spring or other elastic force expansion component, and the third positioning plate 800 may be connected to the second positioning plate 600 through the second elastic member 700 so that the second positioning plate 600 can drive the third positioning plate 800 to push the workpiece 900 through the second elastic member 700. When the workpiece 900 needs to be abutted against the first positioning plate 200, the second positioning plate 600 moves towards the workpiece 900 so that the third positioning plate 800 contacts with the workpiece 900 first, and if the moving amount of the second positioning plate 600 is too large, the too large moving amount is absorbed by the second elastic member 700, so that the second positioning plate 600, the workpiece 900 and the first positioning plate 200 are prevented from being damaged.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. In the technical idea scope of the present invention, it is possible to provide a solution of the present invention with a plurality of simple modifications to avoid unnecessary repetition, and the present invention is not described separately for various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
