Abstract

The utility model relates to a spring limiting jig. The spring limiting jig comprises a limiting base. One end of the limiting base is sunk inwards for forming a cavity. An inward-sunk annular groove is formed in the cavity in the axial direction. The spring limiting jig is simple in structure. By limiting a spring on the annular groove with a certain depth, operation is convenient, the labor intensity of workers is lowered, the work efficiency is improved, the pressure exertion center of spring force is not eccentric, damage of the spring is avoided, and the production cost is lowered.

Description

The spring position-limiting fixture

Technical field

The utility model relates to a kind of spring position-limiting fixture.

Background technique

Spring is a kind of mechanical parts that utilize elasticity to carry out work, in order to motion, the mitigation of controlling parts, impacts or shakes, stores up energy, is widely used in machine, instrument.But at some, use in the device of spring, such as seal arrangement, because spring does not carry out spacing, be applied to the power meeting off center on spring, amplitude of deformation increasing and the deforming degree of spring are increased, thereby impel spring stress to strengthen and excessive fatigue, easily cause the damage of spring, improve cost of production, can cause seal failure simultaneously.

The model utility content

The utility model has overcome the deficiencies in the prior art, and a kind of spring position-limiting fixture simple in structure is provided.

For achieving the above object, the technical solution adopted in the utility model is: a kind of spring position-limiting fixture, comprise position limit socket, and an end of the described position limit socket formation cavity that caves inward, described cavity is provided with the annular groove of indent vertically.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further described position limit socket is cylindric.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further the external groove sidevall of described annular groove extends to the inwall of described position limit socket.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further the degree of depth of described annular groove is 4-10mm.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further the degree of depth of described annular groove is 7mm.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further the center of described position limit socket is provided with spacing hole vertically.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further described spacing hole is rounded.

In preferred embodiment of the utility model, the spring position-limiting fixture comprises that further the sidewall thickness of described position limit socket equates to the height between described position limit socket bottom with described annular groove diapire.

The utility model has solved the defect that exists in the background technique, the utility model is simple in structure, spacing in having the annular groove of certain depth by the end with spring, easy to operate, reduced workman's labor intensity, improved working efficiency, guaranteed that simultaneously the center of exerting pressure of spring force is not eccentric, avoid the damage of spring, reduced cost of production.

Embodiment

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of spring position-limiting fixture, comprise position limit socket 1, and an end of position limit socket 1 caves inward and forms cavity 2, and cavity 2 is provided with the annular groove 3 of indent vertically.

The preferred position limit socket 1 of the utility model is cylindric.

Spacing for the ease of to spring, the external groove sidevall of annular groove 3 extends to the inwall of position limit socket 1, and the water jacket wall of annular groove 3 and the internal face of position limit socket 1 are on same vertical surface.The depth B of annular groove 3 is 4-10mm, and the depth B of further preferred annular groove 3 is 7mm.

The center of the preferred position limit socket 1 of the utility model is provided with spacing hole 4 vertically, and this spacing hole 4 is rounded, but is not limited to circle, can also be for oval, square etc.

The sidewall thickness D of position limit socket 1 equates to the height H between position limit socket 1 bottom with annular groove 3 diapires.

The utility model in use, can first be arranged on position limit socket 1 on a fixed base by spacing hole 4, and this moment, position limit socket 1 was fixed, finally with spring one end embedding tightly in the annular groove 3 with certain depth, guarantee that the spring force center of exerting pressure is not offset.

Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine technical scope according to the claim scope.
