Problems solved by technology

At present, only the two bonnets can be placed on the valve grid manually, and the upper shafts of the front and rear control rods are inserted into the holes of the core body, and the camshaft is inserted into the central shaft of the gas meter at the same time, and then the control rods are lifted and the At one end, adjust the position of the valve cover so that the other end holes of the front and rear control rods are sleeved on the valve cover. The process is complicated and the valve cover is moved back and forth during the operation. When the frame is assembled to the core body, the bonnet needs to be moved again manually so that the groove on the bonnet is in the same direction as the guide rod frame, which increases the risk of damage to the bonnet and valve grid. Auxiliary assembly molds for rods, rear control rods, camshafts, guide rod holders, valve covers

Embodiment 1

[0020] Embodiment 1, as Figure 1-9 As shown, a kind of pointer assembly mold for gas meter assembly includes a lower mold base plate 1 and an upper mold base plate 30; wherein: the lower mold base plate 1 is provided with a number of positioning grooves, threaded holes, Round hole, pin hole, fixing block 2 is fixed in the limiting groove on the bottom plate 1 of the lower mold by screws, the positioning sleeve 3 is fixed in the round hole on the bottom plate 1 of the lower mold by screws, and the limiting block 4 is fixed by a spring hole, the limit block 4 is fixed on the mold bottom plate 1 of the lower mold by screws, the left control rod clamping block 5 is provided with a limit groove and a spring fixing hole, and is fixed on the slider 14 by screws, and the bonnet guide rod frame fixing block 6 is provided with a pin hole, which is fixed on the bottom plate 1 of the lower mold by screws, and the fixed shaft 8 of the pointer plate is designed with a step. The step on the...

Embodiment 2

[0022] Embodiment 2. A five-piece pointer assembly mold for gas meter assembly, in which: pointer 20, pointer disc 21, rear control rod 22, guide rod frame 23, valve cover 24, front control rod 25, valve grid 26 , central shaft 27, and camshaft 28 are parts or components on the core body 29. All the other are with embodiment 1.

Embodiment 3

[0023] Embodiment 3. An assembly mold for five-piece pointer assembly for gas meter assembly, wherein: the mold guide column 31 is inserted into the positioning sleeve 3 and is mated with the positioning sleeve 3 . All the other are with embodiment 1.

[0024] working principle:

[0025]The mold base plate 1 of the lower mold is fixed when it is in use, and the return spring 16 shrinks in a free state to keep the position of the pointer fixed shaft 12 at the initial assembly position, and the pointer 20 is loaded into the imitation pointer cavity on the pointer fixed shaft 12; the pointer disc 21 is placed on the 12 On the pointer fixed shaft disc, the fan-shaped hole on the pointer disc 21 passes through the fan-shaped flange on the pointer 20, and the two grooves on the pointer disc 21 are set on the pointer disc fixed shaft 8 on the bottom plate 1 of the lower mold, and guide The rod frame 23 is put into the slot of the guide rod frame fixing block 6 of the bonnet, the fro...

Abstract

The invention relates to a pointer five-in-one assembly mold for assembly of a gas meter. At present, a method of automatic assembling a machine core is not occurred in the market, the pointer, the transmission parts of a pointer disc, a front control rod, a rear control rod, a cam shaft, a guide rod frame, a valve cover and the like are irregularly in shape in the assembly process of the machinecore of the gas meter after investigation is carried out, the assembling is troublesome, at present, an auxiliary assembling mold of the transmission parts of the pointer, the pointer disc and the like of the gas meter is not existed. The invention relates to a pointer five-in-one assembly mold for assembly of the gas meter. A plurality of positioning grooves, threaded holes, round holes and pinholes are formed in a bottom plate of the mold of a lower mold, and fixing blocks are fixed in limiting grooves in the bottom plate of the mold of the lower mold through screws; and the mold solves the problems that due to the fact that the transmission parts of the pointer, the pointer disc, the front control rod, the rear control rod, the cam shaft, the guide rod frame, the valve cover and the like are irregular in shapes, the difficult assembling is caused.

Description

technical field [0001] The invention relates to the technical field of gas meter assembly, in particular to a pointer five-piece assembly mold used for gas meter assembly. Background technique [0002] Household gas meters are common household gas volume measurement products, and the movement is the main component of the gas meter. At present, there is no automatic assembly movement method in the market. After investigation, during the assembly process of the gas meter movement, the pointer, pointer dial , front control rod, rear control rod, camshaft, guide rod frame, valve cover and other transmission parts have strange shapes, and the assembly is troublesome. The position of the notch on the camshaft needs to correspond to the position of the upper flange of the pointer to be stuck in the groove of the camshaft in the next step; the pointer is first placed in the notch of the pointer disc, and the pointer needs to be rotated so that the upper flange of the pointer is stuc...
