Abstract
The invention discloses a wheel rim installation expansion device comprising a main body column, an expansion plate, and a limit pressing block. A recess inner cavity for limiting is formed in the inner side of the expansion plate; and a groove for limit pressing block installation is arranged in the main body column and a screw hole for screw tightening is formed in the groove. A notch for limiting pressing block passing is formed in one side of the expansion plate. The thickness of the recessed inner cavity is identical with that of the limiting pressing block; and a countersink screw hole is arranged at the limit pressing block. And the expansion device is made of metal materials. According to the invention, on the basis of original rim installation specification keeping, a wheel rim installation expansion device having an expansion plate with the expanded large-scale rim installation dimension is provided.
Description
Technical field
The present invention relates to a kind of wheel rim expanding device is installed.
Background technology
Tire testing is equipped in recent years and is developed greatly, corresponding test equipment is further abundant, there is mileage machine, intensity machine, comprehensive test machines etc. detect the machine that plays key effect to tyre performance, along with scientific and technical development, the wheel rim matching with tire, its diversity is also increasing day by day, but because the wheel rim specification that testing machine can be done to test is limited, cannot meet wheel rim miscellaneous tests, its efficiency test scope is subject to great constraint, particularly for intensity machine, its wheel rim erecting device is without rolling voluntarily, its wheel rim tire of installing is actionless in process of the test, therefore seek one can effectively expand wheel rim install expanding device be very important.
Summary of the invention
The present invention, for reaching above object, provides a kind of and has possessed on the basis of former wheel rim installation specification, expands the wheel rim of the expansion board of a large specification wheel rim installation dimension expanding device is installed.
For addressing the above problem, the present invention adopts following technical proposals:
A kind of wheel rim is installed expanding device, it is characterized in that, this expanding device is made up of main column, expansion board, spacing briquetting.
Described expansion board inner side is useful on the depression inner chamber of position-limiting action, expansion board one side has the breach passing through for spacing briquetting, depression inner chamber thickness and spacing briquetting are equal, cavity shape is C shape, after expansion board is arranged on main column, the screw hole that spacing briquetting is screwed on main column, nearly main column inner side one side does not have breach, can prevent that expansion board from moving backward, after spacing briquetting installs, can limit equally expansion board and move forward and backward, there is the blind hole of radial symmetry in expansion board outside, blind hole is used for installing large specification wheel rim, according to requirements adjusts voluntarily.
Main column has for described spacing briquetting installs groove, has for tighten the screws screw in groove, and groove, for spacing briquetting provides necessary installation site, prevents from causing spacing briquetting displacement because of the movement of expansion board.
On spacing briquetting, have countersunk head screw, object is that screw installs rear screw terminal and can not expose, and avoids stopping the activity space of expansion board.
This expanding device adopts metal material, can guarantee, on the basis in its working strength and serviceable life, can also to adopt other materials material.
Adopt the wheel rim installation expanding device of technique scheme to there is following beneficial effect:
1, provide multiple wheel rim installation specification, on main column, on the basis of original wheel rim mounting hole, expansion board can provide installing space for large specification wheel rim;
2, installation process is simple, and expansion board takes up room little, and dismounting is easily simple, and spacing position only can complete with a screw;
3, stop means arranges ingeniously, and spacing briquetting is arranged on main column, and spacing position is expansion board inner chamber, and on the basis of stress structure that has utilized expansion board, limited briquetting has limited it and moves forward and backward simultaneously.
Accompanying drawing explanation
Figure 1 shows that wheel rim installation expanding device front elevation of the present invention;
Figure 2 shows that the cut-open view of wheel rim installation expanding device of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in Figure 1, a kind of wheel rim is installed expanding device, it is characterized in that, this expanding device is made up of main column 1, expansion board 2, spacing briquetting 3.
As shown in Figure 2, described expansion board 2 inner sides are useful on the depression inner chamber of position-limiting action, expansion board 2 one sides have the breach passing through for spacing briquetting 3, depression inner chamber thickness and spacing briquetting 3 are equal, cavity shape is C shape, after expansion board 2 is arranged on main column 1, the screw hole that spacing briquetting 3 is screwed on main column 1, nearly main column 1 inner side one side does not have breach, can prevent that expansion board 2 from moving backward, after spacing briquetting 3 installs, can limit equally expansion board 2 moves forward and backward, there is the blind hole of radial symmetry in expansion board 2 outsides, blind hole is used for installing large specification wheel rim, according to requirements adjust voluntarily.
On spacing briquetting 3, have countersunk head screw, object is that screw installs rear screw terminal and can not expose, and avoids stopping the activity space of expansion board 2.
This expanding device adopts metal material, can guarantee, on the basis in its working strength and serviceable life, can also to adopt other materials material.
