Description

Automatic tapping device for plastic parts

Technical Field

The utility model relates to the technical field of plastic part processing, in particular to an automatic tapping device for a plastic part.

Background

Among the prior art, the processing has the plastic part of screw hole to need to process on plastic mould and revolves tooth structure, because revolve tooth structure complicacy, the mould processing degree of difficulty is big, and mould manufacturing cost is high, and mould output is few, causes the plastic part cost of moulding plastics to improve greatly, simultaneously because revolve tooth structure wearing and tearing fast, the maintenance cost is high, influences the mould life-span. In order to solve the problems, a method generally adopted is that a worker holds an electric drill by hand to perform secondary processing on a plastic part, the worker needs to align to a position on the plastic part, where a threaded hole needs to be processed, in an operation process, the operation has high technical requirements on the operation of the worker, if the operation is inaccurate in positioning, the threaded hole is easily processed to generate deviation, the defective rate is further increased, the production cost of the plastic part is increased, and the efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides an automatic tapping device for plastic parts, which can effectively solve the problems of high cost and low efficiency in processing plastic parts with threaded holes.

In order to achieve the purpose, the technical scheme provided by the utility model is as follows: an automatic tapping device for plastic parts, which comprises a fixed bottom plate, a lower clamping block, an upper clamping block, a positioning guide block, an electric drill, a reversing switch, a transformer and a power supply, two lower clamping blocks are fixedly arranged on the fixed bottom plate, each lower clamping block is correspondingly connected with an upper clamping block, a groove matched with the peripheral surface of the electric drill is arranged on the surface of each lower clamping block opposite to the upper clamping block, the two grooves form mounting positions for mounting the electric drill, the electric drill is fixed in the two mounting positions, the head of the fixing base plate is provided with a screw tap, two positioning guide blocks are fixed on the fixing base plate and positioned at the two sides of the screw tap, used for placing the plastic part and guiding the movement of the plastic part, the electric drill is electrically connected with the transformer through the reversing switch, the rotating direction of the screw tap is controlled through the reversing switch, and the transformer is electrically connected with the power supply and used for adjusting the current so as to control the rotating speed of the electric drill.

Further, the groove is of a semicircular structure.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

by adopting the automatic tapping device, a tapping structure does not need to be processed on the plastic mould, the production cost of the plastic part is reduced, during operation, a worker only needs to place the plastic part with the threaded hole to be processed between the two positioning guide blocks, and manually operates the plastic part to move along the positioning guide blocks to be in contact with the screw tap to process the threaded hole, so that the requirement on the operation level of the worker is reduced, the production efficiency of the plastic part is improved, and the processing quality of the plastic part is improved.

Detailed Description

The present invention is further illustrated with reference to the following specific examples, but the mode of use of the present invention is not limited thereto.

As shown in fig. 1 to 2, the automatic tapping device for plastic parts in this embodiment includes a fixing base plate 1, lower clamping blocks 2, upper clamping blocks 3, positioning guide blocks 4, an electric drill 5, a reversing switch 6, a transformer 7 and a power supply, wherein two lower clamping blocks 2 are fixedly mounted on the fixing base plate 1, each lower clamping block 2 is correspondingly connected with one upper clamping block 3, a groove 10 matched with the outer peripheral surface of the electric drill 5 is formed on the opposite surface of each lower clamping block 2 and the upper clamping block 3, the groove 10 in this embodiment is of a semicircular structure, the two grooves 10 form mounting positions for mounting the electric drill 5, the electric drill 5 is fixed in the two mounting positions, a tap 9 is mounted on the head of the electric drill, the specification of the tap 9 is determined according to the diameter of a threaded hole to be processed, two positioning guide blocks 4 are fixed on the fixing base plate 1 and located on two sides of the tap 9, a width dimension for placing plastic part 8 and leading to plastic part 8's removal, and interval between these two location guide blocks 4 suits with plastic part 8, electric drill 5 is connected with transformer 7 electricity through change-over switch 6, transformer 7 is connected with power supply electricity for adjust the electric current size in order to control 5 rotational speeds of electric drill.

During the use, will wait to process the plastic part 8 of screw hole and place between two location guide blocks 4 to be located the front side of tap 9, ensure that tap 9 aims at the position that needs to process the screw hole on the plastic part 8, it is rotatory through change-over switch 6 control tap 9, thereby follow plastic part 8 and remove along location guide block 4 and process out the screw hole afterwards. The automatic tapping device of this embodiment, very big reduction to workman operation level's requirement, can effectively improve plastic part production efficiency simultaneously, improve screw hole machining precision, and then improve plastic part processingquality.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that variations based on the shape and principle of the present invention should be covered within the scope of the present invention.
