Abstract
The utility model discloses an assembling-type round broach, which comprises a cutting part A, a replaceable calibrating cutting part B, a wedge-caulking centering part C and a tight-joining part D, wherein, the four parts are independent to each other and are connected with each other in turn when in use; the cutting part A comprises a handle part 1, a neck part 2, a transitional cone 3, a front guiding part 4, a rough cutting tooth 5 and a precise cutting tooth 6, which are connected with each other in turn to form an integrity; the replaceable centering cutting part B comprises an alignment tooth 7 and a rear guiding part 8, which are connected with each other in turn to form an integrity. The round broach has the advantages that the round broach can be repaired for a plurality of times and can be interchanged; when the cutting part of the round broach is used, the rough process and the finishing of the hole can be completed by replacing different replaceable centering cutting part with different sizes; and when the size of the cutting part is worn to be smaller, the inner hole can be processed by replacing the replaceable centering cutting part to be a rough cutting tooth which is domain on the cutting, so that the cost of the cutting tool can be greatly reduced, and the cost performance of the cutting tool can be increased.
Description
Technical field
The utility model relates to aperture knife tool, particularly a kind of assembled round broach.
Background technology
Our the broaching tool structure of use all is all-in-one-piece at present, and it generally is made up of following each one, and the effect of each part has nothing in common with each other: shank---clamping broaching tool, transferring power part; Neck---mark position; The transition awl---play the centring effect; Front pilot---guiding and role of inspection; Cutting portion---undertake the work of cutting earnestly; Calibration portion---scrape light and calibration function, improve surface of the work and slightly release souls from purgatory and precision; Rear pilot and rest portion---all be to play protection, protection and supporting role.Owing to be overall structure, and the size at each position of broaching tool each is different, it is very loaded down with trivial details and difficult that processing is got up, the higher reconditioning surplus of the dimensional accuracy of broaching tool is relatively very little on the other hand, it is less that number of times is reused in reconditioning, so the production cost of broaching tool is higher.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, and provide a kind of and repeatedly repair, the assembled round broach with interchangeability, the production cost of saving broaching tool increases the cutter cost performance.
The purpose of this utility model is achieved through the following technical solutions: the assembled round broach, and it comprises four major parts, cutting tip, interchangeable calibration cutting tip, wedging centering part is pieced together tight part, and four is most of relatively independent, links to each other in turn during use;
Cutting tip comprises: shank, neck, transition awl, front pilot, roughing tooth, finishing tooth, and they connect as a whole in turn;
Interchangeable calibration cutting tip comprises: finishing teeth and rear pilot, they connect as a whole in turn.
By top narration as can be seen, the utlity model has following advantage: can repeatedly repair, has interchangeability, use broaching partly to change the different interchangeable calibration cutting tip of size and just can finish roughing and fine finishining the hole, when the broaching portion size when repeatedly reconditioning diminishes, interchangeable calibration cutting tip changed into based on the finishing tooth parts of cutting process endoporus, the cutter cost performance increases with regard to the cost of charp tool is significantly reduced like this, particularly the broaching processing of using Φ 50 above broaching tools is reduced the cutter expense more than 30%.
Description of drawings
Fig. 1 is the utility model structural representation
Among the figure, the A-cutting tip, the interchangeable calibration cutting tip of B-, C-wedging centering part, D-pieces together tight part, 1-shank, 2-neck, 3-transition awl, 4-front pilot, 5-roughing tooth, 6-finishing tooth, 7-finishing teeth, 8-rear pilot
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the assembled round broach, it comprises four major parts, cutting tip A, interchangeable calibration cutting tip B, wedging centering portion C and the tight part D of assembly, four is most of relatively independent, links to each other in turn during use; Cutting tip A comprises: shank 1, neck 2, transition awl 3, front pilot 4, roughing tooth 5, finishing tooth 6, and they connect as a whole in turn; Interchangeable calibration cutting tip B comprises: finishing teeth 7 and rear pilot 8, and they connect as a whole in turn; Wedging centering portion C is a wedge block, pieces together tight part D for piecing together jack panel.
