Abstract

The utility model discloses a multi-station drilling device, which is used for processing car trunk hinge component products employing A, D and E as positioning references. The multi-station drilling device comprises a first positioning fixture, a second positioning fixture, a third positioning fixture, a first compressing fixture, a second compressing fixture, a first drill bit, a second drill bit, a third drill bit, a fourth drill bit and a fifth drill bit, wherein the positioning fixtures are used for mounting the products, the first positioning fixture employs the D as the positioning reference, the second positioning fixture employs the A as the positioning reference, the third positioning fixture employs the E as the positioning reference, the first compressing fixture and the second compressing fixture correspond to the first positioning fixture and the second positioning fixture respectively, and the first drill bit, the second drill bit, the third drill bit, the fourth drill bit and the fifth drill bit correspond to positions of the products needing drilling. The products are positioned and processed once, accumulated errors caused by processing for multiple times are avoided, product qualification rate is increased from original about 60% to more than 99%, five hole positions of the products are processed once, operating time is shortened from original five minutes to current 0.5 minute, operating efficiency is improved substantially, and the labor intensity of workers is reduced.

Description

The multistation drilling equipment

Technical field

The utility model relates to a kind of drilling equipment, particularly a kind of multistation drilling equipment that the critical piece of car runk hinge is processed.

Background technology

The critical piece of MZ car runk hinge (seeing Fig. 1,2), need processing be 1, the wire harness installing hole of 3 ￠ 6.5 of processing; 2, ￠ 10.0 leaking holes of processing; 3, the hinge case installing hole of a ￠ 6.2 of processing.

Former processing technology:

With A, D, E is positioning reference, 1, on bench drill, process the wire harness installing hole of 3 ￠ 6.5 with two pairs of drill jigs; 2, on bench drill, process ￠ 10.0 leaking holes with one pair of drill jig; 3, on bench drill, process the hinge case installing hole of a ￠ 6.2 with one pair of drill jig.

The problem that exists:

Processing 5 holes needs 5 minutes approximately, and the clamping difficulty; Five holes process respectively through drill jig, take a lot of work, time-consuming, and resetting, hole bit position degree is difficult to guarantee; Because multiple clamping, the product variation after machining is bigger, and the qualification rate of product is about 60%.

The utility model content

The technical problem that the utility model will solve is: in order to overcome problems such as original processing technology clamping difficulty, processing back product variation is big, qualification rate is low, a kind of multistation drilling equipment is provided.

The utility model solves the technical scheme that its technical problem adopted: a kind of multistation drilling equipment; Be used to process car runk hinge member product; This product is a positioning reference with A, D, E, comprises a positioning fixture that is used to install product, No. two positioning fixtures and No. three positioning fixtures, and a positioning fixture is positioning reference with D; No. two positioning fixtures are positioning reference with A; No. three positioning fixtures are positioning reference with E, with a positioning fixture and No. two a corresponding respectively compressing fixture and No. two compressing fixtures of positioning fixture, and a drill bit at the required boring of corresponding product position, No. two drill bits, No. three drill bits, No. four drill bits and No. five drill bits.

A described compressing fixture and No. two compressing fixtures are the pneumatic clamping anchor clamps.

The beneficial effect of the utility model is: the processing of the disposable location of product, avoided the repeatedly accumulated error of processing, and it is original about 60% that product qualified rate has, and brings up to more than 99%;

Process at one time the position, 5 holes of product, operating efficiency shortened to present 0.5 minute by original 5 minutes, had increased substantially operating efficiency, and had reduced working strength of workers.

Fig. 2 is that the A-A of Fig. 1 cuts open (bowing) view;

Fig. 3 is the structural configuration sketch map of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further specified.

As shown in Figure 2; A kind of multistation drilling equipment is used to process car runk hinge member product, and this product is a positioning reference with A, D, E; Comprise a positioning fixture 1 that is used to install product, No. two positioning fixtures 2 and No. three positioning fixtures 3; Positioning fixture 1 is a positioning reference with D, and No. two positioning fixtures 2 are positioning reference with A, and No. three positioning fixtures 3 are positioning reference with E; With positioning fixture 1 and No. two a corresponding respectively compressing fixture 4 and No. two compressing fixtures 5 of positioning fixtures 2, and the drill bit at the required boring of corresponding product position 6, No. two drill bits 7, No. three drill bits 8, No. four drill bits 9 and No. five drill bits 10.

Like Fig. 1, shown in 2, what the critical piece of product MZ car runk hinge need be processed is: the wire harness installing hole of 3 ￠ 6.5 of processing; Process ￠ 10.0 leaking holes; The hinge case installing hole of a ￠ 6.2 of processing.

Multistation drilling equipment through the utility model is seen Fig. 2, processes at one time the position, 5 holes of product.Process is: with A, D, E is positioning reference, 1, product is put on the anchor clamps of drilling equipment; 2, through (hole, pin and profile) pneumatic positioning fixture and two pneumatic clamping anchor clamps with product orientation with compress.3, put down protective plate, start five drilling machines and carry out the machining hole position, boring is moved back automatically, is shut down after accomplishing.4, under the state that boring can't be carried out (bit wear, fracture), autostop (through warning devices such as contact-making switch, sensors).
