Abstract

The utility model relates to an assembling cleaning tool, and one end of a handle is connected with a file (4). The utility model is characterized in that the other end of the handle (3) is connected with a punch, the punch is composed of a big drift punch (2) and a small drift punch (1), and the big drift punch and the small drift punch are an entirety. By adopting this structure, the cleaning tool can not only remove the burrs on the casting surface, but also can remove the septa at the orifice. Accordingly, the cleaning work of the casting is simplified, the cleaning time of the casting is reduced, the work intensity of the operator is relieved, the cleaning cost is lowered and the work efficiency of the operator is enhanced.

Description

The combined type cleaning tool

Technical field

The utility model relates to a kind of cleaning tool, is specifically related to a kind of combined type cleaning tool of removing cast(ing) surface burr and aperture every skin.

Background technology

Usually in the casting process of foundry goods, burr, overlap can appear in the surface that foundry goods contact with mould, and the aperture can occur every phenomenons such as skins, before further processing, need to these cast(ing) surfaces burr, overlap, clear up every skin.Cleaning for cast(ing) surface, normally adopt file deburring, overlap at present, adopt punching pin to remove the aperture every skin, and these cleaning tools all are separately for one, especially punching pin is divided into different specifications according to diameter, when foundry goods being done cleaning, the workman needs to select the punching pin of different size to use according to the size in foundry goods aperture.Since a kind of punching pin of specification can only clear up a kind of diameter circular hole every skin, that clears up the different-diameter circular hole just needs to change the punching pin of respective diameters every skin, then need to select else file when the burr of cleaning cast(ing) surface or overlap, when foundry goods of cleaning, usually need the frequent cleaning tool of changing like this, bring many inconveniences to the operator, and length consuming time, inefficiency.

Summary of the invention

The purpose of this utility model provides a kind of combined type cleaning tool, it has multiple function of use, can remove the cast(ing) surface burr, can remove the aperture again every skin, the cleaning work of foundry goods is simplified, handled easily person's use has alleviated operator's labour intensity, has also improved operator's operating efficiency simultaneously.

The purpose of this utility model is achieved in that an end of handle connects file, and the other end of handle is connected with punching pin, and described punching pin is the integral body that large and small drift constitutes.

Described punching pin and file are respectively by being threaded in the two ends of handle.

Described big drift is a taper seat, and its front end is provided with the little drift of a band taper, and little drift top end face is a disc, and the step surface that big drift combines with little drift is a bit of cylinder.

The utility model has adopted such scheme, the two ends that large and small punching pin and file are fastened on handle by being threaded form a kind of multi-functional cleaning tool, it is removable being threaded and making the cleaning tool workpiece, the large and small punching pin of this cleaning tool can be selected the drifts of different size according to the size difference in foundry goods hole before cleaning, in order to going up every skin of cleaning different size foundry goods hole.Small punch and large punch all are taper, but its top end face all is a disc, the diameter of large punch end face is greater than the diameter of small punch top end face, and small punch bottom surface diameter of a circle equates with large punch end face diameter of a circle, and both combine by a bit of cylinder is one whole and be stairstepping.When cast(ing) surface during jagged or overlap, utilize file in the cleaning work parts can rasp away burr or overlap on the cast(ing) surface, as the Kong Zhongyou of foundry goods during every skin, utilize punching pin in the cleaning work parts can wash out in the hole every skin, so just can under the situation of not changing instrument, finish cleaning work to foundry goods.

The utility model need not changed cleaning tool in scale removal process, the cleaning work of foundry goods is simplified, and has made things convenient for operator's use, reduced the clearance time of foundry goods, alleviate operator's labour intensity, reduced the cost of cleaning, also improved operator's operating efficiency simultaneously.

Below by embodiment the utility model is described further.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a kind of embodiment of the present utility model.

The specific embodiment

With reference to Fig. 1.Described cleaning tool comprises large and

small punching pin

2,1, file 4 and handle 3 parts composition.Large and

small punching pin

2,1 is that an integral body is stairstepping, small punch and large punch all are truncated cone-shaped, large and small punching pin and file are fastened on the two ends of handle 3 by being threaded, also can be fastened on the two ends of handle by other connected mode, as clamping, grafting etc., form a kind of multi-functional cleaning tool.Because punching pin and file be by being threaded in the two ends of handle, thereby punching pin and file all be removable, removable cleaning tool workpiece can choose drift according to the size difference in foundry goods hole before clearing up foundry goods specification.

Referring to Fig. 2, the using method of the multi-functional cleaning tool of this large complicated foundry goods is: the workpiece 5 that will clear up earlier is placed on the workbench, selects large and

small punching pin

2,1 corresponding in the cleaning work parts according to the diameter in hole on the cleaning member.The operator holds handle 3 during work, utilizes the lip-deep diaphragm skin of punching pin or file cleaning workpiece, overlap or burr.When needs remove on the hole on the foundry goods every skin the time, drift is aimed at every skin, hit the afterbody (file) of this cleaning tool with hammer, will clean out every skin; When cast(ing) surface is jagged, with can rasp away fast burr on the foundry goods of the file 4 of this cleaning tool, when cast(ing) surface has overlap, with file overlap is shoveled to use earlier again the cast(ing) surface filing is put in order, so just can under the situation of not changing instrument, finish cleaning work to foundry goods.

Claims

1. combined type cleaning tool, an end of handle connects file (4), and it is characterized in that: the other end of handle (3) is connected with punching pin, and described punching pin is that large and small (2,1) drift constitutes, and large and small drift is as a whole.

2. combined type cleaning tool according to claim 1 is characterized in that: described punching pin and file (4) are respectively by being threaded in the two ends of handle (3).

3. combined type cleaning tool according to claim 1 is characterized in that: the big drift of described punching pin is a taper seat, and its front end is provided with the little drift of a band taper, and little drift top end face is a disc, and the step surface that big drift combines with little drift is a bit of cylinder.
