Abstract
The utility model relates to an upper rim driving lifter. On the premise of utilizing an integral frame structure, guide parallelism provided by a vertical lifting track of an upper rim chuck and runners on two sides of a main frame can be improved and ensured by machining precision rather than a following auxiliary regulating structure and an installation manner, and the precision of lifting and axial locating of a rim is improved integrally at the same time. A driving lifting control method is as follows: the lifter comprises the main frame, and a sliding support can vertically slide in a reciprocating manner along the main frame to finish assembly and disassembly operations of the upper rim chuck born on the sliding support. Before the upper rim driving lifter is assembled, the main frame is manufactured to be of the integral frame structure; and a servo motor drives the sliding support through a lead screw, and the lead screw is parallel to the central line of a vertical shaft of the upper rim chuck so that the servo motor pushes the upper rim chuck from the side part to realize vertical reciprocating movement.
Description
Technical field
The utility model relates to a kind of last wheel rim that is applied to the tire dynamic and balance testing process and drives jacking gear, belongs to the rubber manufacturing machinery field.
Background technology
There is quality non-uniform phenomenon to some extent in rubber tyre in dirt product process, so need carry out dynamic balancing measurement before the tire shipment.Based on existing preparation technology, the vertical testing machine of the more employing of device of tire dynamic and balance test.Tire is mounted, is clamped between the upper and lower wheel rim in process of the test; Drive through rotary main shaft is rotated; And by the induction force numerical value that force transducer the tests out radial and axial stability index of tire of testing and assessing, and then judge whether tire quality reaches the production standard requirement.
The driving such as that existing dynamic balance test machine, last wheel rim go up and down to adopt at large is pneumatic, hydraulic pressure or leading screw and the kind of drive reach the loading to main shaft in the hope of the accurate location of accomplishing in the wheel rim lifting process.
Shown in the accompanying drawing 1 of back; Fix to form the wheel rim framework through screw and entablature (12) at prior art scheme central post (11); Servomotor (13) connects leading screw (15) through band (14) driving synchronously; Under the vertical fixing prerequisite of screw (16), the sliding support (17) that drives the below when leading screw (15) rotates slides to realize the descending operation of wheel rim (18) vertically.
Exist following major defect and use problem in the technique scheme:
1, column (11) very easily causes framework vertical hydraucone to occur, is difficult to guarantee for the depth of parallelism of two side rails (19), thereby exists significant rigging error, can only increase pad through the later stage and revise adjustment;
2, go up the wheel rim framework and be linked and packed, be prone to cause two side rails (19) not in same plane, exist tangible instability through screw;
3, the motion mounting means of leading screw (15) has caused on vertical displacement, reserving its height of 2 times, has increased the assembling height of equipment on the whole, causes the superelevation problem in transportation;
4, servomotor adopts the kind of drive of band (14) synchronously, and not only mounting structure is complicated, and outputting power has tangible decay, and energy loss is bigger, and equipment and maintenance cost are all higher.
Because the special present patent application that proposes.
The utility model content
The said wheel rim of going up of the utility model drives jacking gear; Its purpose is to solve the defective of prior art existence and adopts under the prerequisite of integral type framed structure; The guiding depth of parallelism that the track of the vertical up-down of last wheel rim chuck and the slideway of main frame both sides provide; Can improve and assurance through machining accuracy, rather than accomplish, improve the degree of accuracy that goes up wheel rim integral elevating, axial location simultaneously with follow-up auxiliary adjustment structure and assembling means.
Another purpose of design is, takes the leading screw and the last wheel rim chuck out-of-alignment kind of drive, and leading screw is not done vertical moving and screw drives the vertical slip of sliding support, thereby reduces the setting height(from bottom) of integral device, only reserves the assembling height of 1 times of leading screw self.
Purpose of design is that also servomotor adopts the coaxial drive mode, and mounting structure is simple, and the outputting power attenuation rate is lower.
For realizing above-mentioned purpose of design, the described wheel rim driving jacking gear of going up mainly includes:
One main frame is equipped with on main frame and drives sliding support along the vertical servomotor that reciprocatingly slides, and sliding support carries goes up the wheel rim chuck.
The difference with the prior art part is that main frame has the general frame structure of integral type,
Servomotor drives sliding support through leading screw, and leading screw is parallel with the vertical shaft centre line of last wheel rim chuck.
Comparatively preferably driving with the gear train scheme is, servomotor connects through shaft coupling and drives the leading screw that sidepiece is fixed in main frame, and sliding support is connected in the screw that is set on the leading screw.
Carrying out the vertical guidance quality improvement project that reciprocatingly slides to sliding support is, the vertical both sides of main frame are provided with slideway, and several slide block sets that are connected in sliding support are located at slideway.
Content to sum up, the utility model is said to be gone up wheel rim and drives the advantage that jacking gear has and have:
1, go up go up and down check and correction precision, the guide rail depth of parallelism of required unthreaded hole relative position of wheel rim and can access effectively and guarantee, simplify significantly and reduce subsequent installation and debugging difficulty, the reference system degree of accuracy of integral elevating device is higher.
2, take the leading screw and the last wheel rim chuck out-of-alignment kind of drive, can reduce the setting height(from bottom) and the headspace height of integral device effectively, help follow-up Performance Detection and tire industry production procedure.
3, servomotor adopts the coaxial drive mode, and mounting structure is simple, and the energy consumption of outputting power is lower.
