A base positioning block is fixed on a base board, two crank arm limiting parts are fixed on two sides of the upper surface of the base board, two C-shaped or U-shaped crank arms are arranged on two sides of the upper portion of the base board, a rotational lower end of each crank arm is mounted beside each crank arm limiting part, a crank arm boss engaged with each crank limiting part is arranged at the rotational end of each crank arm, a pressing block mechanism is fixedly connected above the crank arm, the pressing block mechanism comprises a pressing block, a screw rod and a guide rod, the pressing block is connected to the lower end of the screw rod via threads, and the guide rods are arranged on two sides of the screw rod and are sleeved on the pressing block. The pressing block component is driven to rotate to one side by the crank arms, and then an assembly space on the upper portion of the base is set aside, thereby bringing convenience for direct assembly of the base, springs and the contact from top to down. A pressing portion of the pressing block is defined by the crank arm limiting parts, thereby guaranteeing assembling position and precision between the contact and the base. In addition, the contact assembly fixture with rotational crank arms is light in weight and convenient in moving and can reduce labor intensity.
Description
Technical field
The utility model relates to the low voltage electrical equipment processing technique field, relates in particular to the contact of low-voltage circuit breaker and the assembling jig of insulating base.
Background technology
At present, the major function that is applied in the assembling jig of contact in the low-voltage circuit breaker and insulating base is that contact is assemblied on the insulating base.As shown in Figure 1, in the groove on pedestal 11 tops, put spring 12, will put on then axle 5 contact 10 be placed on spring 12 above, each sheet contact 10 bears the pressure of two springs, is approximately about 100N.The anchor clamps downforce that utilization is positioned at contact 10 tops presses to contact 10 and requires the position, make in axle 5 half slots of falling on the pedestal 11 13 of contact 10 centres, whole assembling process is had relatively high expectations to positional precision, anchor clamps are subjected to certain spring force, therefore, the structural design to anchor clamps has proposed higher requirement.
The assembling jig defective of present employed contact and insulating base is:
One, because pedestal 11, spring 12 and contact 10 these three kinds of parts must be put into clamp body simultaneously, in put procedure, because contact 10 floats on spring 12, therefore, the whole put procedure of three kinds of parts is effort, inconvenient operation.
When two, pedestal 11 was placed on the pedestal locating piece, the position can not be fixed, and when the anchor clamps of contact 10 tops press down, can't guarantee the rigging position and the assembly precision of 11 of contact 10 and pedestals.
Summary of the invention
The purpose of this utility model is for overcoming the defective that the anchor clamps assembling is inconvenient, assembly precision is low of contact and insulating base in the prior art, has proposed a kind of easy to assembly, contact assembling jig with rotatable connecting levers that production efficiency is high.
The technical solution adopted in the utility model is: fixed pedestal locating piece on base plate, two connecting lever locating parts are fixed on both sides above the base plate, the connecting lever of two C types or U type is positioned at both sides, base plate top, the rotatable lower end of connecting lever is installed in by the connecting lever locating part, rotatable end at connecting lever is provided with a connecting lever boss that matches with the connecting lever locating part, at the upper fixed connection forming machanism of connecting lever.
Described forming machanism comprises briquetting, screw rod and guide post, and briquetting is installed guide post by being threaded in the screw rod lower end in the screw rod both sides, and guide post is placed on the briquetting.
The beneficial effects of the utility model are:
1, rotatable connecting levers rotates to a side with the briquetting parts, has got out of the way the assembly space on pedestal top, has made things convenient for the direct assembling from top to down of pedestal, spring, contact, has improved operating efficiency in actual production.
2, determine the depressed position of briquetting by the connecting lever locating part, guaranteed rigging position and assembly precision between contact and the pedestal.
3, whole assembling jig is in light weight, is convenient to move in assembling process, has alleviated labour intensity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the build-up member figure of contact 10, pedestal 11 and spring 12.
Fig. 2 is the structure chart before the assembling of the utility model anchor clamps.
Fig. 3 is the structure chart after the assembling of the utility model anchor clamps.
Among the figure: 1. pedestal locating piece; 2. base plate; 3. connecting lever locating part; 4. connecting lever boss; The axle; 6. connecting lever; 7. briquetting; 8. screw rod; 9. guide post; 10. contact; 11. pedestal; 12. spring; 13. pedestal half slot.
Embodiment
As Fig. 2, the utility model is made up of mechanism components such as base plate 2, pedestal locating piece 1, connecting lever locating part 3, connecting lever 6, briquetting 7, screw rods 8, wherein, pedestal locating piece 1 by screw on base plate 2, have two connecting levers 6 that are designed to C type or U type to be positioned at the both sides on base plate 2 tops, two connecting lever locating parts 3 are fixed on the both sides above the base plate 2.The lower end of two connecting levers 6 is rotatable structure, the upper end is a fixed structure, the rotatable end of connecting lever 6 is installed in connecting lever locating part 3 next doors, and connecting lever 6 is connected on the connecting lever locating part 3 by hole and pin, a connecting lever boss 4 is set on the rotatable end of connecting lever 6 to match with connecting lever locating part 3, when connecting lever 6 rotation, connecting lever boss 4 is touched on the corresponding connecting lever locating part 3 and spacing by connecting lever locating part 3.The upper fixed end of connecting lever 6 connects forming machanism, this forming machanism comprises briquetting 7, screw rod 8 and guide post 9, briquetting 7 is by being threaded in screw rod 8 lower ends, guide post 9 is installed in screw rod 8 both sides, guide post 9 is placed on the briquetting 7, and guide post 9 can prevent briquetting 7 rotations when screw rod 8 is done rotation, like this, briquetting 7 just only moves up and down under the drive of screw rod 8, does not rotate.
Before being placed on the build-up member of Fig. 1 on the pedestal locating piece 1,, the forming machanism of upper end is rotated to a side, just can get out of the way pedestal 11 directly is placed on space on the pedestal locating piece 1 from the top down earlier by two rotatable connecting levers 6.During concrete operations, can earlier pedestal 11 be placed on the pedestal locating piece 1, placing the gap can be controlled in the very little scope, guarantee the positional precision of pedestal 11 and pedestal locating piece 1, then, spring 12 is placed in the groove of pedestal 11 again, at last contact 10 is placed on the spring 12 together with axle 5, the whole operation process is simple, convenient.
As shown in Figure 3, when pedestal 11, spring 12, contact 10 are placed on the pedestal locating piece 1, pulling connecting lever 6, make the forming machanism on top rotate to the service position on contact 10 tops together with connecting lever 6, at this moment, connecting lever locating part 3 is by no longer rotating after arriving the service position with making connecting lever 6 cooperating of connecting lever boss 4, then by rotary screw 8, make briquetting 7 downward translations, pressing contact 10 to overcome spring force and be moved down into rigging position.Because the certain distance of pivot of the axis deviation connecting lever 6 of screw rod 8, therefore, when briquetting 7 is overcoming in the process of spring force, connecting lever 6 can be subjected to a clockwise torque all the time, connecting lever boss 4 on the connecting lever 6 is adjacent on connecting lever locating part 3, and can be rotated counterclockwise around pivot.Like this, contact 10 just under the drive of briquetting 7, is pushed into axle 5 and pedestal 11 upper half-round slots 13 concentric position.
