Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Referring to fig. 1-8, a positioning and fixing device for a component of an electric tool according to the present invention includes a main body 1, a base 2, a clamping member 6, and a driving assembly. The main body 1 is a ring structure, and is fixed on the base 2 through bolts. Three sets of clamping members 6 are distributed on the main body 1. In this embodiment, three sets of clamping members 6 are distributed on the main body 1 in a circumferential array. The clamping member 6 is connected with the main body 1 in a vertical rotating manner and comprises a first extension section 61 and a second extension section 62 which are connected with each other and have included angles. The angle between the first extension 61 and the second extension 62 is preferably greater than 90 °. The first extension sections 61 of the clamping members 6 enclose a clamping space therebetween. The part to be processed is placed in the clamping space and is received by the top surface of the main body. The first extension 61 can be moved toward or away from the clamping space by rotating the clamping member 6.

As shown in fig. 8, the driving assembly is installed between the clamping members 6, and includes a center base 3, a driving portion connected to the center base 3, and a driving mechanism for driving the center base 3 to move up and down. The aforementioned driving portion is installed corresponding to each clamp. The drive portion comprises two abutments 31 arranged spaced up and down. One end of the two abutting pieces 31 at the same side is fixedly connected with the central seat 3, and one end of the other side extends towards the direction far away from the central seat 3. The second extension 62 is movably mounted between the two abutments 31. Through the above structure design, when the central seat 3 moves downward, the abutting member 31 at the upper side abuts against the second extending section 62, and forces the second extending section 62 to swing toward one side, and further drives the first extending section 61 to move toward the direction close to the clamping space, thereby reducing the clamping space. When the center base 3 moves upward, the abutting member 31 at the lower side abuts against the second extending section 62, and forces the second extending section 62 to swing toward the opposite side, so as to drive the first extending section 61 to move away from the clamping space, thereby expanding the clamping space. The clamping or loosening of the parts is realized by combining the modes.

The drive mechanism 4 is preferably an electric push rod. The central base 3 is detachably and fixedly connected with the driving mechanism 4.

As shown in fig. 6, a cavity 11 is formed in the main body 1 corresponding to each clamping member 6. The clamping member 6 is movably mounted in the cavity 11. A shaft body 63 is formed on the clamping member 6. As shown in fig. 7, the shaft body 63 is formed at two side positions of the second extending section 62. Vertical grooves 12 are formed in the side wall of the cavity 11 corresponding to the two ends of the shaft body 63. The lower end of the vertical groove 12 is closed, and the upper end forms a socket. The bottom surface of the vertical groove 12 is semicircular and is matched with the peripheral surface of the shaft body 63. The two ends of the shaft body 63 are in inserting fit with the vertical grooves 12 on the corresponding sides through the inserting openings, and a fit state is formed. In this embodiment, in this engaged state, the end surface of the shaft body 63 is in clearance fit with each side wall of the vertical groove 12, and the shaft body 63 can move up and down and rotate in the vertical groove 12. The side surface of the main body 1 is formed with insertion holes 13 corresponding to each of the vertical grooves 12. The insertion hole 13 extends in the width direction of the vertical groove 12, and communicates with the vertical groove 12. The positioning and fixing device of the embodiment comprises a plug pin 5 which is used for being in plug fit with a jack 13. In the aforementioned fitting state, when the plug pin 5 is inserted into the insertion hole 13, the two ends of the shaft 63 are limited between the plug pin 5 and the bottom of the limiting groove 12 (as shown in fig. 4). Through the above structural design, the shaft body 63 can rotate in the vertical groove 12 without moving in the direction under the cooperation of the latch 5 and the vertical groove 12. When the bolt 5 is pulled out, the clamping element 6 can be removed from the vertical groove 12. The bolt 5 is an integrated structure and comprises two inserting ends. The plug end is matched with the two jacks 13 at the corresponding positions, so that the bolt 5 can be synchronously plugged into the two jacks 13 at the corresponding positions.

In this embodiment, at least two sets of vertical slots 12 are spaced apart in a direction toward or away from the center position of the clamping space. By selecting the vertical slots 12 in different positions, the position of the clamping part 6 can be adjusted, and the adjustment of the initial space size of the clamping space can be realized.

As shown in fig. 3 and 7, the first extension 61 has a first side facing the clamping space. The first side has a first protrusion 64 formed thereon. When the first extension section 61 clamps the component, the first protrusion 64 can abut against the component to improve the stability of clamping. The second extension 62 has a second side facing the two abutments 31. The two second side surfaces are respectively formed with a second protrusion 65. The abutment member 31 abuts with the second extension 62 through the second projection 65.

When the clamping device is used specifically, parts to be positioned and fixed are placed on the top surface of the main body and located between the clamping pieces 6. The driving mechanism 4 drives the central base body 3 to move downwards, the abutting piece 31 located on the upper side moves downwards along with the central base body, the second extending section 62 of the clamping piece 6 is forced to rotate downwards, and then the first extending section 61 is driven to abut against the side face of the part, so that the part is clamped and fixed. Drive central pedestal 3 rebound through actuating mechanism 4, the butt 31 that is located the downside follows rebound to force the second extension 62 of clamping piece 6 to rotate upwards, and then drive the side that spare part was kept away from to first extension 61, thereby realize loosening of spare part. The clamping range of the clamping piece 6 can be adjusted by adjusting the clamping piece 6 to be inserted into the vertical grooves 12 at different positions.

The fixed location that this embodiment can realize electric tool's spare part fast is fixed, effectively satisfies the batch processing demand of each spare part, and can realize the regulation of the tight scope of clamp of each clamping piece 5, effectively satisfies the fixed location demand of the electric tool spare part of different overall dimension.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
