Abstract

The utility model discloses a deflection coil clamping device, which has a baseplate arranged at one side of a bracket, the baseplate is arranged with an adjustable bolt, an upper and a lower clamping arms are suited on the adjustable bolt, both clamping arms are provided with an upper and a lower connecting plates, the upper connecting plate and the lower connecting plate are connected through a guide wheel, the upper connecting plate is also arranged with a handle, and a pull spring is arranged between the upper and lower connecting plates, both the clamping arms are arranged with an upper and a lower clamping chucks connected with the upper and lower clamping arms through the upper and lower fixing plates. Due to the upper and lower clamping chucks are vertically positioned on the upper and lower clamping arms, the clamping mode can give high clamping force and is easier to move vertically, the clamping stability and reliability are improved; the transverse guide shaft on the adjustable bolt can adjust the central position of the upper and lower clamping chucks along the vertical direction, thus being suitable for the adjustment of different size of kinescope and deflection coil.

Description

A kind of deflecting coil clamping device

One, technical field

The utility model relates to a kind of mechanical clamping device, particularly a kind of picture tube manufacture process deflecting coil clamping device that is used for.

Two, background technology

In the production of kinescope process, parts such as picture tube, coil, combination magnetic spare are assembled, and projects such as the convergence of picture tube video picture picture, distortion, colour purity, inclination are detected, adjust is the operation of a key, realizes the assembling of picture tube and yoke assembly and adjusts operation by the adjustment machine.In the work adjustment process of the machine of adjustment, at first to clamp, locate deflecting coil, realize adjusting by deflecting coil travel mechanism and rotating mechanism then, deflecting coil fixedly be the key of whole adjustment process, present employed deflecting coil clamping device is fixed on the support, and two bearing pins and left and right connecting rod and clamping limb are formed a rigid body, and handle is fixed on the connecting rod, fixed head and clip are fixed on the jig arm, and two springs are connected on connecting rod and the support.Pull handle at work downwards, the clip along continuous straight runs opens; Upwards pull handle, the clip along continuous straight runs closes up.But this clamping device has the following disadvantages: for the right side deflecting coil of terminal block is arranged, it is longer that the chuck of this method of clamping will become, and this makes the rigidity variation of mechanism, inconvenient operation; Owing on the horizontal direction deflecting coil is clamped, because the influence of deflecting coil deadweight, the clamping dynamics is not enough, the stability of holding action, reliability decrease simultaneously; For the picture tube and the deflecting coil of unidimensional specification, this clamping device can not be adjusted narrow application range accordingly with the variation of the centre-height of deflecting coil on the adjustment machine.

Three, summary of the invention

The purpose of this utility model is to overcome the shortcoming of the technology of above-mentioned appearance, provides a kind of fixedly requirement, holding action that can adapt to the different size deflecting coil convenient, deflecting coil clamping device reliably.

For achieving the above object, the technical solution adopted in the utility model is: comprise support and the base plate that is arranged on support one side, be characterized in, base plate is provided with the adjustment screw rod, the upper end of adjusting screw rod is provided with fixed head, on the adjustment screw rod between base plate and the fixed head, be set with symmetrical upper clip arm and lower clip arm, be respectively arranged with symmetrical upper junction plate and lower connecting plate in the both sides of upper clip arm and lower clip arm, upper junction plate is connected by guide wheel with lower connecting plate, on upper junction plate, also be provided with handle, and between upper junction plate and lower connecting plate, also be provided with extension spring, on upper clip arm and lower clip arm, also be provided with upper mounted plate and bottom plate, on upper mounted plate and bottom plate, be respectively arranged with upper grip and lower chuck.

Another characteristics of the present utility model are: also be provided with the axis of guide parallel with adjusting screw rod between base plate and the fixed head, upper clip arm and lower clip arm are sleeved on vertical guide shaft; Also be provided with the horizontal guide shaft that has chute that is sleeved on adjustment screw rod, extension spring and the axis of guide between upper clip arm and the lower clip arm, guide wheel and horizontal guide shaft adopt and are slidingly connected, and laterally guide shaft is threaded with the employing of adjustment screw rod.

Because upper and lower chuck of the present utility model is vertically set on the upper and lower jig arm, the clamping great efforts of this method of clamping, and moving have flexibly in vertical direction improved the steadiness and the reliability of holding action; Can regulate upper and lower chuck center in the position of vertical direction by the horizontal guide shaft that is arranged on the adjusting screw(rod), thereby adapt to the adjustment operation of different size picture tube and deflecting coil.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.

Referring to Fig. 1, the utility model comprises support 1 and is arranged on the base plate 2 of support 1 one sides, base plate 2 is provided with adjusts screw rod 3 and vertical guide shaft 8, the upper end of adjusting screw rod 3 and vertical guide shaft 8 is provided with fixed head 7, on the adjustment screw rod 3 between base plate 2 and the fixed head 7 and vertical guide shaft 8, be set with symmetrical upper clip arm 9, lower clip arm 9-1 and the horizontal guide shaft 13 that has chute, laterally guide shaft 13 adopts with adjusting screw(rod) 3 and is threaded, be respectively arranged with symmetrical upper junction plate 5 and lower connecting plate 4 at upper clip arm 9 and lower clip arm 9-1 both sides, upper junction plate 5 is connected by guide wheel 14 with lower connecting plate 4, guide wheel 14 adopts with horizontal guide shaft 13 and is slidingly connected, on upper junction plate 5, also be provided with handle 6, and between upper junction plate 5 and lower connecting plate 4, also be provided with extension spring 12, on upper clip arm 9 and lower clip arm 9-1, respectively be provided with upper mounted plate 10 and bottom plate 10-1, on upper mounted plate 10 and bottom plate 10-1, be respectively arranged with upper grip 11 and lower chuck 11-1.

The utility model is pulled handle 6 downwards, makes lower connecting plate 4 and upper junction plate 5 be in the dead-centre position of angle 180 degree, and mechanism realizes self-locking, and upper grip 11 and lower chuck 11-1 separately unclamp coil; Upwards pull handle 6, make lower connecting plate 4 and upper junction plate 5 break away from angle 180 degree dead-centre positions, clip vertically relies on the effect of extension spring 12 to close up the clamping coil, because the screw of the horizontal guide shaft 13 of the utility model adopts with adjustment screw rod 3 and is threaded, rotate and adjust screw rod 3, laterally guide shaft 13 will move up and down along guide post 8, change in the position of vertical direction thereby drive the upper and lower chuck of fixture 11 centers that are fixed thereon, to adapt to the adjustment operation of different size picture tube and deflecting coil.
