Abstract

The utility model discloses a tool for a motor pressing pin. The tool comprises a fixing frame, wherein the fixing frame is composed of a base plate, a side plate and a top plate. An inverted cylinder is fixed on the top plate, and an upper die is fixed on a sliding plug of the cylinder and provided with an upper arc block cavity with the same radius as a motor rotating shaft. The upper die above the upper arc block cavity is further provided with an upper groove for inserting the pin, the depth of the upper groove is equal to the length of the pin exposed out of the motor rotating shaft, a lower die is fixed on the base plate and provided with a lower arc block cavity with the same radius as the motor rotating shaft, the lower arc block cavity is located under the upper arc block cavity, the lower die below the lower arc block cavity is further provided with a lower groove for inserting the pin, the depth of the lower groove is larger than that of the upper groove, and the tool further comprises a pressure buffering system. The tool has the advantages that the tool is simple in structure and convenient and safe to use, extension lengths and sizes of the pins processed through the tool are consistent, and the pins and the motor rotating shaft are not damaged.

Description

The tooling device of motor pad

Technical field

The utility model relates to a kind of frock for the electric motor of automobile assembling.

Background technology

In the automobile fan motor assembling process, it is the hole of pin being compressed into rotating shaft that a procedure is arranged, in the prior art, normally beaing pin with hammer assembles, its shortcoming is: 1, pin extension elongation size is inconsistent, during motor pin assembling flabellum, causes flabellum to pack into; 2, pin bending and motor damage.

The utility model content

The utility model has proposed a kind of tooling device of motor pad in order to overcome above deficiency, utilizes cylinder as power, uses Mould Machining.

The technical solution of the utility model is:

A kind of tooling device of motor pad; comprise: base plate; the fixed mount that side plate and top board are formed; inverted cylinder is fixedly arranged on the top board; the cunning of cylinder fixedly has mold beyond the Great Wall; mold is provided with the last circular arc piece cavity identical with the machine shaft radius; also be provided with on the top mold of last circular arc piece cavity for the upper groove that inserts pin; the degree of depth of upper groove equals the length that pin exposes machine shaft; bed die is fixedly arranged on the base plate; bed die is provided with the following circular arc piece cavity identical with the machine shaft radius; this time circular arc piece cavity be positioned at circular arc piece cavity under; also be provided with on the below bed die of following circular arc piece cavity for the low groove that inserts pin; the degree of depth of this low groove is greater than the degree of depth of upper groove, thereby it is indeformable only to be subjected to unidirectional pressure with the protection pin.

Also comprise: two symmetrically arranged long vertical rods, this length vertical rod is fixed on the bed die fixed mount, the bed die fixed mount is fixed on the described base plate, and described bed die is provided with the long sliding hole supporting with long vertical rod, is parallel to long vertical rod and also is provided with two symmetrically arranged short slide bars, this weak point slide bar is fixed on the bed die fixed mount, bed die is provided with the short slide opening supporting with short slide bar, on the short slide bar stage clip is installed, by this structure, can cushion unnecessary pressure, guarantee that machine shaft is indeformable.

The tooling device of a kind of motor pad of the utility model has following beneficial effect: safety simple in structure, easy to use, and through pin extension elongation consistent size, pin and the equal not damaged of machine shaft of this tooling device processing.

Description of drawings

Fig. 1 is side view of the present utility model.

Fig. 2 is overall structure schematic diagram of the present utility model.

The specific embodiment

Now by reference to the accompanying drawings the utility model is further described:

As Fig. 1, shown in Figure 2, a kind of tooling device of motor pad, comprise: base plate 23, the fixed mount that side plate 22 and top board 21 are formed, inverted cylinder 1 is fixedly arranged on the top board 21, the cunning of cylinder 1 fixedly has mold 3 beyond the Great Wall, mold 3 is provided with the last circular arc piece cavity 32 identical with motor 8 rotating shaft radiuses, also be provided with on the top mold 3 of last circular arc piece cavity 32 for the upper groove 31 that inserts pin 51, the degree of depth of upper groove 31 equals the length that pin 51 exposes motor 8 rotating shafts, bed die 53 is fixedly arranged on the base plate 23, bed die 53 is provided with the following circular arc piece cavity 52 identical with motor 8 rotating shaft radiuses, this time circular arc piece cavity 52 be positioned at circular arc piece cavity 32 under, also be provided with on the below bed die 53 of following circular arc piece cavity 32 for the low groove that inserts pin 51, the degree of depth of this low groove is greater than the degree of depth of upper groove 31.

Fixedly there is the concrete grammar of bed die 53 to be on the base plate 23, also comprise: two symmetrically arranged long vertical rods 4, this length vertical rod 4 is fixed on the bed die fixed mount 7, bed die fixed mount 7 is fixed on the described base plate 23, described bed die 53 is provided with the long sliding hole supporting with long vertical rod 4, be parallel to long vertical rod 4 and also be provided with two symmetrically arranged short slide bars 62, this weak point slide bar 62 is fixed on the bed die fixed mount 7, bed die 53 is provided with the short slide opening supporting with short slide bar 62, lacks on the slide bar 62 stage clip 61 is installed.

During use, motor 8 rotating shafts are placed on the following circular arc piece cavity 52 of bed die 53, with the hole in the pin 51 insertion rotating shafts, pin 51 is aimed at upper groove 31, start the valve switch of cylinder 1 air inlet, the sliding plug of cylinder 1 drives mold 3 and presses down, and the degree of depth that is pressed onto upper groove 31 equals the length that pin 51 exposes motor 8 rotating shafts.
