Abstract
The utility model relates to a seal structure for tire dynamic balance testing machine location locking device, its structural design characterized in that adopts O shape sealing washer on the installation contact surface A of last rim and positioning core axle, and same O shape sealing washer sealed form also uses under on the installation contact surface B of rim and guide holder. The utility model discloses the seal structure that technical scheme provided can cooperate well and trade the automatic change that the rim mechanism accomplished different specification rims automatically, guarantees the sealed index of requirement simultaneously, moreover, but adopts O type sealing washer sealed greatly reduced machining precision, and then reduce cost has improved the benefit.
Description
Technical field
The utility model is a kind of hermetically-sealed construction that is used for the dynamic balance test machine positioning and locking device, and it relates to the improvement on the present tire positioning and locking device hermetically-sealed construction, belongs to structure and tire building, detection technique field.
Background technology
Dynamic balance test machine is applied to the dynamic balance running of vertical car, light truck tire and all steel load tire.At present, widely used Series Tyre dynamic balancer, its tire positioning and locking device be by a live axle, a wheel rim that is connected with live axle, and a tire that is installed on the wheel rim is formed.This tire positioning and locking device can't be used for the automatic replacing of wheel rim.Its version as shown in Figure 1, among the figure, 1 is positioning core axle, 2 is last wheel rim, 3 is guide holder, 4 are following wheel rim, 5 is latch segment, 6 is locking cylinder, 7 is base.
When this mechanism worked, servomotor fell to inserting guide holder 3 by driving the positioning core axle 1 by the mechanical paw clamping, located back locking cylinder 6 and promoted latch segments by profile of tooth location clamping and positioning mandrel 1; And be individually fixed in the upper and lower wheel rim of positioning core axle 1 and guide holder 3, and detection tire in place, thus and in tire, inflate the positioning and locking of realizing tire by pneumatic system.Among the figure, because A, the B two sides of this mechanism are lapped face mechanical seal, the manufacturing cost height.In addition, owing to need to detect different types of tyre, change the wheel rim of different size exactly, in the process of dismounting, above-mentioned A, B two sides can be subjected to constantly wearing and tearing and influence the effect of sealing, cause prohibited data detection true.
Summary of the invention
The purpose of this utility model designs at existing above-mentioned shortcoming on the present device just a kind of hermetically-sealed construction that is used for the dynamic balance test machine positioning and locking device is provided, to solve under the continuous situation about changing of wheel rim, guarantee the sealing of balancer positioning and locking device, requirement can be reduced simultaneously greatly, so just cost of processing can be reduced widely the sealing contact surface machining precision.
The purpose of this utility model realizes by following measure:
This kind is used for the hermetically-sealed construction of dynamic balance test machine positioning and locking device, its structural design features is, adopt O-ring seals on the installation surface of contact A of last wheel rim and positioning core axle, same O-ring seals seal form is also used on the installation surface of contact B of following wheel rim and guide holder.
Description of drawings
Fig. 1 is existing dynamic balance test machine positioning and locking device and the one-piece construction synoptic diagram that comprises the described hermetically-sealed construction of technical solutions of the utility model
Embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1, this kind is used for the hermetically-sealed construction of dynamic balance test machine positioning and locking device, it is characterized in that: on the installation surface of contact A of last wheel rim 2 and positioning core axle 1, adopt O-ring seals 8, this O-ring seals model is 180X3.55, sealing manufacturer by German De Shi provides, same O-ring seals seal form is also used on the installation surface of contact B of following wheel rim 4 and guide holder 3, and this O-ring seals model is 250X7, also is to seal manufacturer by German De Shi to provide.
The hermetically-sealed construction that technical solutions of the utility model provided can cooperate well from moving the automatic replacing that wheel rim mechanism finishes the different size wheel rim, guarantee the sealing index of requirement simultaneously, and, adopt the sealing of O RunddichtringO can reduce machining precision greatly, and then reduce cost, improved benefit.
Claims (1)
1. hermetically-sealed construction that is used for the dynamic balance test machine positioning and locking device, it is characterized in that: go up at the installation surface of contact A of last wheel rim (2) and positioning core axle (1) and adopt O-ring seals (8), same O-ring seals seal form also to use on the installation surface of contact B of following wheel rim (4) and guide holder (3).
