Abstract
The utility model discloses a kind of round-link chain tensioning auxiliary appliance, comprise pulling force seat and be positioned at half round pin of pulling force seat for clamping rings chain, half round pin is provided with the breach that can pass through for round-link chain, a transition sleeve is provided with between described pulling force seat and half round pin, transition sleeve has a breach passed through for round-link chain vertically, the breach alignment on the breach on transition sleeve and half round pin.The utility model only can meet the testing requirements of plurality of specifications round-link chain with a set of pulling force toilet, when testing different round-link chains, only need change transition sleeve and half round pin and need not change pulling force seat, it is convenient to change, and both reduces cost, and turn improves work efficiency.
Description
Technical field
The utility model relates to a kind of round-link chain tensioning auxiliary appliance, belongs to testing machine technical field.
Background technology
Round-link chain tensioning auxiliary appliance conventional at present mainly contains pulling force seat and half round pin composition.Half round pin is semicircular ring structure, and the carrying circular hole on its excircle dimension and pulling force seat is measure-alike; Inner circle shape and size are identical with half chain link, identical with stress when ensureing round-link chain stress at the trial and actual use.This correspond to a set of pulling force seat and half round pin with regard to the round-link chain determining a kind of specification, just needs to change many cover pulling force seats and half round pin when testing multiple round-link chain.And pulling force holder structure is complicated, processing difficulties, physical dimension is large, changes inconvenient, neither economical and practical, have impact on work efficiency again.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of round-link chain tensioning auxiliary appliance of highly effective.
In order to solve the technical problem, the technical solution adopted in the utility model is: a kind of round-link chain tensioning auxiliary appliance, comprise pulling force seat and be positioned at half round pin of pulling force seat for clamping rings chain, pulling force seat is provided with the breach that can pass through for round-link chain, a transition sleeve is provided with between described pulling force seat and half round pin, transition sleeve has a breach passed through for round-link chain vertically, the breach alignment on the breach on transition sleeve and pulling force seat.
Further, be provided with a carrying circular hole in described pulling force seat, transition sleeve and half round pin are positioned at carrying circular hole.
Further, the external diameter of described transition sleeve and the carrying Circularhole diameter of pulling force seat measure-alike, internal diameter is identical with the excircle dimension of half round pin, and the inner circle shape and size of half round pin are identical with half chain link.
Further, described round-link chain tensioning auxiliary appliance has the transition sleeve and half round pin that overlap more and match with the round-link chain of different size.
The beneficial effects of the utility model: the utility model comprises pulling force seat, half round pin and transition sleeve, for different round-link chains, half round pin is different with the size of transition sleeve, when testing different round-link chains, only need change transition sleeve and half round pin, pulling force seat need not be changed.Transition sleeve phase specific thrust holder structure is simple, easily processes, lightweight, and it is convenient to change, and both reduces cost, and turn improves work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, pulling force seat, 2, half round pin, 3, transition sleeve, 4, round-link chain, 5, carrying circular hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model be described further and limit.
As shown in Figure 1, a kind of round-link chain tensioning auxiliary appliance, a kind of round-link chain tensioning auxiliary appliance, comprise pulling force seat 1 and be positioned at half round pin 2 of pulling force seat 1 for clamping rings chain 4, pulling force seat 1 is provided with the breach that can pass through for round-link chain 2, be provided with a transition sleeve 3 between described pulling force seat 1 and half round pin 2, transition sleeve 3 has a breach passed through for round-link chain 4 vertically, the breach alignment on the breach on transition sleeve 3 and pulling force seat 1.
In the present embodiment, be provided with a carrying circular hole 5 in described pulling force seat 1, transition sleeve 3 and half round pin 2 are positioned at carrying circular hole 5.The external diameter of described transition sleeve 3 is identical with the diameter dimension of the carrying circular hole 5 of pulling force seat 1, and internal diameter is identical with the excircle dimension of half round pin 2, and the inner circle shape and size of half round pin 2 are identical with half chain link.
In the utility model, pulling force seat 1 only has a set of, for the round-link chain of different size, has transition sleeve 3 and half round pin 2 that many cover sizes are different.When testing different round-link chain, only need change transition sleeve 3 and half round pin 2 and pulling force seat 1 need not be changed.
Claims (4)
