Description

The shoe brake sectional fixture

Technical field

The utility model relates to anchor clamps, more specifically says so in the process of drum brake, for finishing the anchor clamps that friction material are attached to required use on the steel hoof.

Background technology

In the process of drum brake, friction material is attached to needs specific anchor clamps on the steel hoof.In friction material applying process, after the light hoof that utilizes the cylinder handle to be with the band friction material of steel ring is propped up, use fixture support, by heat treatment friction material is attached on the light hoof.

At present existing two kinds of form anchor clamps, as shown in Figure 1 a kind of, at the two ends of helix tube 2 screw rod of different rotation directions is set respectively to be threaded, i.e. left-hand screw bar 3 and right handed worm 4, thus but constitute the connecting rod of length reduction.In the use, the light hoof that will be with the band friction material of steel ring by support bar 1 supports, and rotates helix tube 2, and left-hand screw bar 4 and right handed worm 3 are moved to two ends, so connecting rod elongation, work piece is inserted in annealing device and is heat-treated, finish heat treatment after, the backward rotation helix tube 2 again, the screw rod that makes two ends is to central mobile, connecting rod is received weak point, can take out work piece subsequently, enters next working procedure.Though this version is simple, immeasurable chemical control system, operative employee's amount of labour is big, and the efficiency in the work is low, and when producing in enormous quantities, output is lower, and the front and back procedure can't normally be connected, and the result has strengthened production cost, has increased energy resource consumption.Another kind is the sleeve structure setting by cylindrical bar core 2 and pipe cover 3 as shown in Figure 2, and stage clip 4 is sleeved on the periphery of pipe cover 3, and is pressed between two gripper shoes 1, but constitutes the connecting rod of reduction with this.In the use, at first producing the elastic force that air pressure overcomes stage clip with cylinder makes connecting rod be compressed, on gripper shoe, fixedly install work piece, remove cylinder pressure subsequently, connecting rod recovers its elongation, and work piece promptly is placed in the Equipment for Heating Processing, after waiting to finish heat treatment, with the cylinder pressurization, shorten length of connecting rod and can take out work piece once more.In this version, owing to be to be handgrip part, operate also and very easily cause " tong " even if wear gloves with the stage clip body, simultaneously, the length under the connecting rod elongation state is non-adjustable, brings the limitation in the application.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, the shoe brake sectional fixture that provide a kind of and can hand safely, the length under the connecting rod elongation state can necessarily be adjusted is to satisfy large-scale production, to enhance productivity, ensure workman's personal safety.

The utility model technical solution problem adopts following technical scheme:

The utility model version is that the supported on both sides plate that is used for the clamping work piece is and is symmetrical set, and is " worker " shape by telescopic connecting rod and connects.

Design feature of the present utility model is that described telescopic connecting rod is telescopic pogo barrel, is provided with one section polished rod section as holding rod on described pogo barrel.

Design feature of the present utility model also is:

Polished rod section as holding rod on the described pogo barrel is the pipe cover, described pipe cover is fixedly connected on the side gripper shoe, fixedly connected cylinder core bar on the opposite side gripper shoe, described pipe cover and the axial sliding fit of cylinder core bar, compressible pipe spring is sleeved on the periphery of cylinder core bar, and is pressed on the pipe end of pipe cover.

Fixedly connected with bolt and the clamp nut that is equipped with between described cylinder core bar and the gripper shoe.

Between described pipe cover and cylinder core bar, setting is by the kidney slot hole and be inserted in the circumferential detent mechanism that the alignment pin in the kidney slot hole constitutes, and wherein, the kidney slot hole is positioned on the cylindrical core, and alignment pin is fixedly installed on pipe and puts.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model is by being provided with one section polished rod section as holding rod on pogo barrel, the operator directly hands in this polished rod section position, and is safe and reliable, can not cause tong, thereby can shorten the operating time, reduce the amount of labour, reduce danger coefficient, operation well is connected before and after making.

2, the utility model is to fixedly connected with bolt and the clamp nut that is equipped with between cylinder core bar and gripper shoe, this version makes the length under the connecting rod elongation state can obtain certain adjustment, and it is more widely used in the work piece of different model.

3, enforcement of the present utility model need not be changed clamping platform, cylinder and steel ring on working equipment, easy to implement.

4, the utility model can effectively improve 1.5 times with production efficiency.

5, the circumferential detent mechanism of the utility model be provided with can effectively avoid the cylinder core bar and and pipe cover between relatively rotate, improve functional reliability.

Below, in conjunction with the accompanying drawings the utility model is further described by the specific embodiment:

The specific embodiment

Referring to Fig. 3, be used for the left gripper shoe 1 of clamping work piece and right gripper shoe 6 and be and be symmetrical set, be " worker " shape with telescopic connecting rod each other and connect.

In the present embodiment, telescopic connecting rod is a sleeve structure, be to constitute by being fixedly connected on pipe cover 3 on the left gripper shoe 1 and cylinder core bar 2 sliding sleeves that are fixedly connected on the right gripper shoe 6, pipe spring 4 is sleeved on the periphery of cylinder core bar 2, and pipe spring 4 ends are butted on the pipe end of pipe cover 3.

In concrete the enforcement, be to fixedly connected between cylinder core bar 2 and the right gripper shoe 6 with bolt 7 and the clamp nut 8 that is equipped with, regulate the restraint location of clamp nut 8 on bolt 7, make anchor clamps because length of connecting rod obtains adjusting, can be at the work piece of certain scope endoadaptation different model.

Referring to Fig. 4, Fig. 5, right for fear of pipe cover 3 with the relative commentaries on classics between the cylinder core bar 2, between pipe cover 3 and cylinder core bar 2 setting by the kidney slot hole be inserted in the circumferential detent mechanism that the alignment pin in the kidney slot hole constitutes.As shown in Figure 3, kidney slot hole 9 is positioned on the cylinder core bar 2, and alignment pin is fixedly installed in the dowel hole 5 on the pipe cover 3.

In the use, at first whole anchor clamps are placed on the clamping platform, cylinder pressurizes in the lateral of left and right sides gripper shoe, and the pipe spring is compressed, and connecting rod is shortened; The brake light hoof fixed placement that will have friction material again on the gripper shoe of the left and right sides, corresponding placement steel ring outside it again; With the exhaust hood pressure release, utilize the elastic force of pipe spring that work piece is propped up, drop into heat treatment; Finish after the heat treatment process, again by the cylinder pressurization, shorten the length of connecting rod, anchor clamps take off from the clamping platform together with work piece integral body, drop into follow-up oven dry then, and final unloading from gripper shoe finished bonding shoe plate.
