Description

Integrated clamping and fixing tool

Technical Field

This scheme belongs to the machining field, and concretely relates to integral type presss from both sides tight fixed frock.

Background

The production process of a machine refers to the whole process of making a product from raw materials (or semi-finished products). For machine production, the raw material transportation and preservation, production preparation, blank manufacturing, part processing and heat treatment, product assembly and debugging, painting and packaging and the like are included. In the process of machining mechanical parts, in order to meet the technological requirements of machining operation, the workpiece is clamped and positioned in the machining operation, the workpiece can be accurately positioned, the machining operation process is simple and smooth, the technological requirements of accurate machining and quick machining are met, and a clamping tool is required to be used.

Chinese patent discloses a clamping device convenient to adjust with publication No. CN105458775A, and the device is through arranging the pressure disk in on the extension board, adjusting the position of placing of pressure disk, adjusting the pressure plate again and compressing tightly the position, twist off the nut and make the lower nut move downwards, the lower nut is tentatively fixed the pressure plate. And then the upper nut is screwed downwards to move the upper nut downwards so as to fix the upper nut. And simultaneously, the upper nut and the lower nut are used for fixing the position of the pressing plate, so that the pressing plate is clamped. This patent technique has small, simple structure, presss from both sides tightly firm, conveniently adjusts horizontal position and vertical position, the clamping process is simple quick, but its position that need adjust the clamping piece repeatedly at the process of pressing from both sides tightly, and the work piece is at the easy perk of the in-process of pressing from both sides tightly to shadow follow-up processing. Therefore, an integrated clamping and fixing tool is provided to solve the problems in the background art.

SUMMERY OF THE UTILITY MODEL

This scheme provides a tight fixed frock of integral type clamp to the position of clamping piece needs to be adjusted repeatedly to the solution, and the work piece is at the problem of the easy perk of tight in-process of clamp.

In order to reach above-mentioned purpose, this scheme provides a tight fixed frock of integral type clamp, includes: the device comprises a frame, a top block and a top cover; the top block is arranged on the rack in a sliding manner; it is characterized by also comprising; a gear and a rack; the top block is provided with a screw rod fixedly connected; the gear is coaxially connected with the screw rod; the gear is meshed with the rack; the width of the gear is greater than the width of the rack: the rack is provided with a stop block.

The principle of the scheme is as follows: on placing the frame with the work piece, the screw rod at both ends is rotatory to rack one side simultaneously, and then moves the screw rod and remove to the work piece, and then promotes the kicking block and presss from both sides tight work piece, and the gear that drives both ends is rotatory to the rack side simultaneously, because wheel and rack meshing, the rack moves down under the drive of gear, drives the dog on the rack and moves down, and then makes the top cap compress tightly the work piece to reach tight effect of clamp. After the workpiece is machined, the screw rod is rotated reversely to enable the ejector block to be far away from the workpiece, and meanwhile, the gears at the two ends rotate in opposite directions, so that the rack moves upwards, and the top cover loosens the surface of the workpiece, so that the workpiece is taken down.

The scheme has the beneficial effects that: to traditional clamping device, adjust through the nut and compress tightly the work piece, this scheme utilizes the meshing relation of wheel and rack, only needs to rotate the screw rod to drive gear revolve, and then drive the rack and move down, thereby compress tightly the work piece, simple structure not only, convenient operation, the practicality is strong, can use with not unidimensional work piece, need not adjust repeatedly moreover, can guarantee work piece both ends level, the convenient clamp work piece fast more.

Furthermore, the top of the top block is provided with a chamfer angle, the purpose is to leave a gap between the top block and a workpiece, which is convenient for effectively avoiding contact stress, is the most important reason that the installation is convenient and the assembly surface is protected,

further, the middle part of the bottom of the frame is provided with a first groove, and the purpose of the first groove is used for placing a machine tool and fixing the tool.

Further, a second groove is formed in the machine frame; the end face of the second groove is provided with a fixedly connected spring; the free end of the spring is fixedly connected with a gasket, so that the error caused by vibration generated in the machining process of the rack is ensured through pretreatment, and the effect of supporting workpieces of different models is ensured.

Furthermore, the free end of the screw rod is provided with a rotating wheel which is fixedly connected, so that the force of the rotating wheel used during rotation is increased, and the operation is convenient.

Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a frame 1, a top cover 2, a workpiece 3, a top block 4, a screw rod 5, a rotating wheel 6, a shaft sleeve 7, a gear 8, a sliding groove 9, a threaded hole 10, a gasket 11, a spring 12, a rack 13, a first groove 1401 and a second groove 1402.

The embodiment is basically as shown in the attached figure 1:

the bottom of the frame 1 is provided with a first groove 1401 for placing a machine tool and fixing the tool, the middle of the frame 1 is provided with a groove, the bottom of the groove is provided with a through hole, when the workpiece 3 is drilled, guiding the cutter, placing the workpiece 3 at the groove correspondingly, arranging a slidable ejector block 4 on two side walls of the top of the frame 1, arranging a chamfer angle on the top of the ejector block 4, aiming at leaving a gap between the workpiece 3 and the ejector block 4, so as to effectively avoid the contact stress, mainly facilitate the installation and protect the assembly surface, arranging a screw rod 5 fixedly connected with the ejector block 4 on the side surface of the ejector block 4, arranging a rotating wheel 6 on the free end of the screw rod 5, facilitating the rotation of the screw rod 5, sleeving an internal thread shaft sleeve 7 matched with the screw rod 5 on the screw rod 5, the screw is used for guiding the screw 5 to move, and the side wall of the frame 1 and the shaft sleeve 7 are provided with matched threaded holes 10 for fixing the shaft sleeve 7 on the side wall of the frame 1 by using screws. When the runner 6 rotates, the screw 5 moves towards the workpiece 3 side under the fixation of the shaft sleeve 7, and then the ejector block 4 is pushed to move towards the workpiece 3, so that the ejector block 4 abuts against the workpiece 3.

As shown in fig. 2:

the screw 5 is provided with a gear 8 which is coaxially connected, the width of the gear 8 is wide, the gear 8 is provided with a rack 13 which is meshed with the gear, the top of the rack 13 is provided with a stop block, the rack 1 is provided with a positioning hole, and the rack 13 slides in the positioning hole. A top cover 2 is arranged above the machine frame 1, and a through hole is formed in the middle of the top cover 2 and used for guiding a cutter when a workpiece 3 is drilled, so that machining precision is guaranteed. When the rotating wheel 6 rotates clockwise, the screw rod 5 is driven to rotate, and then the gear 8 is driven to rotate clockwise, the gear 8 is meshed with the rack 13, so that the rack 13 is driven to move downwards, and the top cover 2 is driven to move downwards due to the action of the stop block, so that the workpiece 3 is pressed tightly.
