A kind of straight type bone plate hole processing clamp
The present invention relates to clamping tooling technical field, specifically a kind of fixture when hole machined carries out to straight type bone plate.
Bone plate, in the middle of the treatment of orthopaedics patient, plays irreplaceable effect, and in the process of bone plate, because the length equidimension of bone plate is not quite similar, therefore, the clamping of bone plate is very important for the mach precision of guarantee.In the prior art, a kind of hole processing clamp of straight type bone plate is badly in need of.
Summary of the invention
The object of the present invention is to provide a kind of straight type bone plate hole processing clamp, adding the problem of the clamping inconvenience of bone plate in man-hour for solving straight type bone plate.
The present invention solves the technical scheme that its technical problem takes: a kind of straight type bone plate hole processing clamp, it is characterized in that, it comprises pedestal, crossbeam, the first slide rail, the second slide rail, swinging block and motor, described pedestal is slidably fitted with crossbeam, between described crossbeam and pedestal, is provided with the driving mechanism driving cross beam movement; Described crossbeam is fixed with the first slide rail, described pedestal is fixed with second slide rail that arrange corresponding to the first slide rail, first, second slide rail is respectively equipped with the chute of circular arc, in described chute, is slidably fitted with swinging block, described swinging block is fixed with montant; Vertically be fixed with cross bar at the free end of montant, cross bar described in each has been threaded screw rod, and described in each, the free end of screw rod is fixed with a pressure ball; Described pedestal is provided with motor, and described motor is connected with the rotating disk be rotatably installed on the second slide rail by transmission mechanism, and the edge of described rotating disk is fixedly connected with the swinging block on the second slide rail.
Further, be provided with pair of guide rails at the top of described pedestal, be provided with two slide blocks in the bottom of described crossbeam, slide block described in two is connected with two slide respectively.
Further, described driving mechanism comprises and is fixed on feed screw nut bottom crossbeam, is rotatably installed on pedestal and the leading screw coordinated with feed screw nut and the handle being fixed on leading screw drive end.
Further, described transmission mechanism is tape handler, and the driving pulley of described V belt translation is fixed on motor output shaft, and the driven pulley of described V belt translation arranges with rotating disk is concentric and is fixedly connected with.
The invention has the beneficial effects as follows: one provided by the invention straight type bone plate hole processing clamp, realizes the adjustment of the spacing of the first slide rail and the second slide rail by the rotation of leading screw, can realize the clamping to various length bone plate; Make pressure ball and the second slide block mating reaction clamp straight type bone plate by rotary screw, it is firm to clamp.By the swing of driven by motor swinging block, realize the processing in diverse location hole, whole fixture, automaticity is high, easy to operate, easy to utilize.

Detailed description of the invention
Below in conjunction with accompanying drawing, present invention is described.
As shown in Figures 1 to 6, pedestal 1 is basic components of the present invention, is provided with pair of guide rails 11 at the top of pedestal, is provided with a supporting seat 12 between two guide rails, supporting seat is rotatablely equipped with a leading screw 13, is provided with one handle 14 at the drive end of leading screw.Above pedestal, be provided with a crossbeam 2, be provided with a feed screw nut 21 in the bottom of crossbeam, feed screw nut coordinates with leading screw.Bottom the crossbeam of feed screw nut both sides, be fixed with slide block 22 respectively, slide block is installed with corresponding slide.Be provided with column at the top of crossbeam, being fixed with the first slide rail 3, first slide rail at column top is semicircular metalwork, and the first slide rail is provided with semicircular chute.Also be fixed with column at the other end of pedestal, be fixed with the second slide rail 4, second slide rail at the top of this column identical with the planform of the first slide rail, and the second slide rail is corresponding with the first slide rail arranges.
Be respectively equipped with swinging block 5 in chute on the first slide rail and the second slide rail, each swinging block is fixed with a montant 51 respectively, montant is arranged along the radial direction of the first slide rail.Be fixed with a cross bar 52 on the top of montant, cross bar is vertical with montant to be arranged.As shown in Figure 3, Figure 4, each cross bar is respectively equipped with a screw rod 53, and screw rod is threaded with cross bar, and two screw rods is fixed with pressure ball 54 respectively.
As shown in Figure 5, Figure 6, pedestal is fixed with motor 62, swinging block on second slide rail is fixedly connected with a rotating disk 55, dial rotation is arranged on the second slide rail, V belt translation 6 between rotating disk and motor, the driving pulley of V belt translation is fixed on motor output shaft, driven pulley 61 and the coaxial setting of rotating disk of V belt translation.The rotation of the swinging block on swinging block is driven by motor and V belt translation.During installation, according to the distance between length adjustment first slide rail of straight type bone plate and the second slide rail, realize by rotary handle 14, then the two ends of straight type bone plate are placed on corresponding swinging block, rotary screw makes the pressure ball 54 of screw rod free end contact with straight type bone plate and extrude, and now straight type bone plate is just firmly clipped between pressure ball and swinging block.Then, the cutter action on lathe can be driven, realize the processing to straight type bone plate.
