Abstract
The utility model belongs to assembly fixture provides a compression bolt, include: the high first nut (5) of two -sided briquetting (2), annular knurl and threaded (6), threaded (6) lower part is smooth round bar, and the system screw thread is attacked on threaded (6) upper portion, high first nut (5) the screw -thread fit of threaded (6) upper portion and annular knurl, and two -sided briquetting embedding frock is passed to threaded (6) lower part, and press at two -sided briquetting (2) upper surface annular knurl high first nut (5) below, and press at the frock upper surface two -sided briquetting (2) below, and two -sided briquetting (2) degree of compressing tightly to the frock upper surface is adjusted in rotatory annular knurl high first nut (5). The utility model discloses the processing degree of difficulty and the expense of compression bolt combined mechanism mounting hole have been reduced, avoid destroying frock frame construction, the work of easily reprocessing is implemented, the efficiency of compression bolt combined mechanism's installation is improved.
Description
Technical field
The invention belongs to assembly tooling, relate to a kind of hold-down bolt.
Background technology
(1 is high-head knurling screw as shown in Figure 1, 2；2 is two-sided briquetting；3 is frock framework；4 is pressure
Tight face), existing hold-down bolt combined mechanism is by a two-sided briquetting (HB572-89) and one or two pieces rolling
High head screw (GB834-88) is spent to form.Compression mode drills screwed hole on frock framework or matrix, rolling
After spending high head screw to screw, two-sided briquetting being produced thrust, two-sided briquetting will compress by contacting with the face of product
Power passes to product, thus plays the function compressing product.
Existing hold-down bolt combined mechanism is primarily present the unreasonable part in terms of following two:
Need on frock framework or matrix, drill screwed hole, screwed hole to drill technique relatively circular hole complicated, processing
Costly.
Hold-down bolt combined mechanism needs because using, and need to repeatedly dismantle, easily cause the screw thread in screwed hole impaired.
Screw thread after impaired, when reprocessing, need to destroy frock framework or basal body structure, reclamation work performance difficulty and cost
The highest.
Summary of the invention
The purpose of the present invention: propose a kind of hold-down bolt, reduces difficulty of processing and the expense of installing hole；Avoid brokenly
Bad frock frame structure, it is easy to reclamation work is implemented；Improve the installation effectiveness of hold-down bolt combined mechanism.
Technical scheme: a kind of hold-down bolt, including:
Two-sided briquetting (2), annular knurl height head nut (5) and threaded (6)；Threaded (6) bottom is smooth
Round bar, the threaded screw thread in threaded (6) top, threaded (6) top and annular knurl height head nut (5) screw thread
Coordinating, threaded (6) bottom embeds frock through two-sided briquetting, and annular knurl height head nut (5) lower section is pressed in double
Face briquetting (2) upper surface, two-sided briquetting (2) lower section is pressed in frock upper surface, rotates annular knurl height head nut (5)
Regulate the two-sided briquetting (2) compaction degree to frock upper surface.
Advantages of the present invention: present invention reduces difficulty of processing and the expense of hold-down bolt combined mechanism installing hole
With；Avoid damage to frock frame structure, it is easy to reclamation work is implemented；Improve hold-down bolt combined mechanism
Installation effectiveness, concrete contrast sees following table, and (in table, data are respectively to manufacture 10 installations in frock manufacturing shop
Kong Hou, the average data of statistics).
Existing hold-down bolt combined mechanism and optimization bolt combination mechanism contrast table:
Accompanying drawing illustrates:
Fig. 1 is existing hold-down bolt combined mechanism schematic diagram.
Fig. 2 is existing hold-down bolt combined mechanism effect schematic diagram.
Fig. 3 is the hold-down bolt schematic diagram that the present invention optimizes.
Fig. 4 is the boring schematic diagram of workflow of the present invention.
Fig. 5 be workflow of the present invention make pin schematic diagram.
Fig. 6 is the installation two-sided briquetting schematic diagram of workflow of the present invention.
Fig. 7 be workflow of the present invention screw high head knurled nut's compressing component schematic diagram.
Detailed description of the invention:
Below in conjunction with the accompanying drawings the present invention is described in further detail.
The present invention provides a kind of hold-down bolt, as it is shown on figure 3, include:
Two-sided briquetting 2, annular knurl height head nut 5 and threaded 6；Threaded 6 bottom is smooth round bar, screw thread
The threaded screw thread in pin 6 top, threaded 6 top and annular knurl height head nut 5 threaded engagement, threaded 6 bottom is worn
Cross two-sided briquetting and embed frock, below annular knurl height head nut 5, be pressed in two-sided briquetting 2 upper surface, two-sided briquetting 2
Lower section is pressed in frock upper surface, rotates annular knurl height head nut 5 and regulates the two-sided briquetting 2 compression to frock upper surface
Degree.
The present invention optimizes bolt combination mechanism as shown in figs. 4-7, implements according to the following steps, specific as follows:
Step one: boring (7 is boring, and 8 is frock).
Step 2: play pin (6 is threaded).
Step 3: install two-sided briquetting (2 is two-sided briquetting).
Step 4: screw high head knurled nut's compressing component (5 is annular knurl height head nut).
Claims (1)
1. a hold-down bolt, it is characterised in that including:
Two-sided briquetting (2), annular knurl height head nut (5) and threaded (6)；Threaded (6) bottom is smooth
