Abstract
The utility model discloses a clamp body used for a hub falling weight impact test. The clamp body comprises clamping bases, a clamping shaft, a link stopper, a nut and an anvil block. The pair of clamping bases is symmetrically installed on the anvil block. Grooves are formed in the clamping bases. A stepped shaft is arranged at one end of the clamping shaft, and threads are arranged at the other end of the clamping shaft. The link stopper is installed on the clamping shaft. The nut is matched with the thread part of the clamping shaft. The clamp body has the advantages that the product structure is simple, novel and unique, and the radial impact test can be effectively performed on a hub, so that the hub is not restrained by radial force, and test precision is improved.
Description
Technical field
The utility model relates to clamp technology field, specifically relates to a kind of clamp body that carries out falling weight impact test for wheel hub.
Background technology
Along with the develop rapidly of auto industry, the security of automobile, comfortableness, operability also more and more receive people's concern.As the wheel of automobile vitals, the quality of its performance, has vital impact to the security of car load, stability, operability.In wheel Performance Detection.Wheel impact test is one of the most basic, most important test, so advanced technology, the good testing equipment design of security performance have great significance to wheel impact test.At present, to wheel hub radial impact testing, be that its wheel hub center is clamped, wheel hub has been carried out omnibearing spacing fixing, thereby this mode is applied with additional force to wheel hub in radial direction, badly influences the radial impact testing precision of wheel hub.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of clamp body that carries out falling weight impact test for wheel hub, and the technical scheme of employing is as follows:
A clamp body that carries out falling weight impact test for wheel hub, is characterized in that, comprises grip slipper, clamp axis, block, nut and anvil block; A pair of described grip slipper in a symmetrical arrangement is installed on described anvil block; On described grip slipper, offer groove; Described clamp axis one end is provided with a multidiameter, and one end offers screw thread; Described block is arranged in described clamp axis; Described nut coordinates with the threaded portion of described clamp axis.
The beneficial effects of the utility model are: product structure is simple, novel unique, can effectively to wheel hub, carry out radial impact testing, makes it not retrained by radial load, has improved test accuracy.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model;
Fig. 3 is A-A sectional structure schematic diagram in Fig. 2 of the present utility model;
In figure: 1 grip slipper, 2 clamp axis, 3 blocks, 4 nuts, 5 anvil blocks.
The specific embodiment
With reference to Figure of description 1 to 3 pairs, accompanying drawing a kind of clamp body that carries out falling weight impact test for wheel hub of the present utility model, be described in detail below.
A clamp body that carries out falling weight impact test for wheel hub, is characterized in that, comprises grip slipper 1, clamp axis 2, block 3, nut 4 and anvil block 5; A pair of described grip slipper 1 in a symmetrical arrangement is installed on described anvil block 5; On described grip slipper 1, offer groove, this groove is not subject to the power of vertical direction for clamp axis; Described clamp axis 2 one end are provided with a multidiameter, and for locating wheel hub in horizontal direction, one end offers screw thread; Described block 3 is arranged in described clamp axis, for stationary hub; Described nut 4 coordinates with the threaded portion of described clamp axis 2.
During test, first wheel hub is packed in clamp axis 2, reinstall block 3, fastening nut 4, finally puts into clamp axis 2 groove of grip slipper 1.When wheel hub is subject to impacting, not retrained by radial load like this, improved test accuracy.
The above, be only the specific embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
