Description

Tool for positioning and clamping small and medium-sized products on machine tool

Technical Field

The utility model relates to a machine tool anchor clamps field, concretely relates to medium-size and small-size product location presss from both sides tight instrument of using on lathe.

Background

The positioning and clamping of the machine tool mostly adopts the structure of a pull rod, a pressing plate and a compression nut, the bottom of the pull rod is often set to be in a threaded rod structure to be matched with a threaded hole in a T-shaped block at the bottom, the T-shaped block is matched with a T-shaped groove in a workbench of the machine tool, during clamping, the T-shaped block needs to be moved to a designated position and then fastened with the compression nut, the actual machining process is usually directed at products with different structures, the positioning and clamping positions of the products are often different, the pull rod needs to be disassembled again, the T-shaped block at the moment is often not in the original T-shaped groove and needs to be adjusted again and then is connected with the pull rod again, although the process is seemingly simple, the positioning and clamping of the products are usually multiple sets of pull rods, pressing plates and compression nuts, once the position of each set of positioning and compression structure is changed, and the operation is very complicated.

To the problem that above-mentioned prior art exists, the utility model discloses a medium-size and small-size product location is tight and is used instrument tightly on manufacturing the lathe, overcomes above-mentioned defect.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a pair of tight instrument of using of middle-size and small-size product location clamp on lathe can make things convenient for the quick adjustment of dog in different T type grooves through the location structure who changes traditional pull rod bottom, guarantees the locate function of dog in T type groove simultaneously.

In order to realize the purpose, the utility model adopts the technical scheme as follows: a tool for positioning and clamping small and medium-sized products on a machine tool comprises a pull rod and a stop block, wherein a threaded hole is formed in the center of the stop block, and the bottom of the pull rod is in threaded connection with the stop block through the threaded hole;

the stop block is a cuboid, the width of the stop block of the cuboid is smaller than that of a chute above the T-shaped groove on the machine tool platform, and the length of the stop block of the cuboid is larger than that of a chute below the T-shaped groove on the machine tool platform;

two opposite angle positions above the stop block are respectively provided with a triangular groove, and the triangular grooves are symmetrically arranged relative to the central axis of the threaded hole.

Preferably, the distance between the vertical surfaces of the steps at the inner sides of the two triangular grooves is smaller than the width of the sliding groove above the T-shaped groove on the machine tool platform.

Preferably, the distance between the bottom surface of the triangular groove and the bottom surface of the block is 1/3-2/3 of the thickness of the block.

The utility model discloses an useful part lies in:

the utility model discloses having made things convenient for the dog to follow the quick transfer in a T type groove to another T type inslot, not needing the dog to enter into the assigned position from the spout both ends, the dog not only can satisfy the threaded connection action of pull rod in lathe platform T type inslot, can also utilize triangle groove structure spacing in T type groove simultaneously, guarantees the locate function of pull rod bottom.

Drawings

Fig. 1 is a schematic structural view of a tool for positioning and clamping small and medium-sized products on a machine tool.

In the figure: 1-pull rod, 2-stop block and 3-triangular groove.

Detailed Description

To facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a tool for positioning and clamping small and medium-sized products on a machine tool comprises a pull rod 1 and a stop block 2, wherein a threaded hole is formed in the center of the stop block 2, and the bottom of the pull rod 1 is in threaded connection with the stop block 2 through the threaded hole;

the utility model discloses dog 2 is established to the cuboid, and the width of the dog 2 of cuboid is less than the width of the spout above the T type groove on the lathe platform to make things convenient for dog 2 can freely put into T type groove bottom, and the length of the dog 2 of cuboid is greater than the width of the spout below the T type groove on the lathe platform, thereby guarantees pull rod 1 and dog 2 threaded connection in T type groove, has avoided dog 2 to spin in T type groove;

two diagonal positions in 2 tops of dog are equipped with a triangle recess 3 respectively, and the relative screw hole center axis symmetry of triangle recess 3 sets up, the utility model discloses the distance between 3 inboard step facades of two triangle recesses is less than the width of T type groove top spout on the lathe platform, rotates certain angle with dog 2 during the use to promote dog 2 through pull rod 1, utilize two triangle recesses 3 with dog 2 spacing in T type groove, guarantee the locate function of pull rod 1 bottom.

For the taut intensity of guaranteeing 1 bottom of pull rod, the distance of 3 bottom surfaces of triangle recess and 2 bottom surfaces of dog is 1/3-2/3 of 2 thickness of dog, is limited to the actual contact surface of triangle recess 3 and far is less than the contact surface of traditional T type piece certainly, the utility model discloses dog 2 structure is only applicable to the location clamp of middle-size and small-size product tightly.

The utility model discloses a concrete operation process:

firstly, placing small and medium-sized products on a machine tool workbench, then utilizing a pull rod 1 to be connected with a stop dog 2 which is arranged in a T-shaped groove in advance, rotating the stop dog 2 by a certain angle after connection, lifting the stop dog 2 through the pull rod 1, utilizing two triangular grooves 3 to limit the stop dog 2 in the T-shaped groove, and then utilizing a pressing plate and a compression nut to clamp and position the small and medium-sized products.

After the completion processing, change another product, when the location position changes, only need reverse dog 2 again, make 2 length direction of dog and spout length direction coincidence, directly draw out dog 2 can to place the position department that new spout corresponds with pull rod 1 and dog 2, the repetition rotates dog 2 certain angle again, and promotes dog 2 through pull rod 1, utilizes the action that two triangle recess 3 are spacing dog 2 in T type groove.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes, modifications and/or alterations to the present invention may be made by those skilled in the art after reading the technical disclosure of the present invention, and all such equivalents may fall within the scope of the present invention as defined by the appended claims.
