Technical Field

The utility model relates to a new energy automobile technical field especially relates to a single tube spring clamp dismouting anchor clamps of dc-to-ac converter.

Background

The single tube is used as a basic power device and is widely applied to inverters. The fixation of the single tube is a problem that has to be considered when using the single tube. Especially in the automobile industry with severe vibration environment, the reliable fixation of the single tube is a necessary prerequisite for the normal operation of the single tube. At present, the single tube is fixed mainly in two ways: one is that the pressure plate is matched with the screw to press the single tube, and the other is that the spring clamp is used for clamping.

However, the method of using screws for compression requires a tightening process, the assembly is relatively cumbersome, and the clamping force provided by the screws is difficult to control in a small range; the spring clamp is used, and the spring clamp needs to be spread first in the assembling process, and the single tube is clamped at the loading position. If each single tube uses a single spring clamp, the spring clamps are more in number and troublesome to assemble; if a plurality of single tubes supply a spring clamp, then the reusability of spring clamp is not strong, need use new spring clamp when the single tube quantity is different, and the spring clamp of unifying more needs bigger power to strut it at the assembling process, and the inconvenient operation needs to use the mechanical equipment of customization to accomplish.

Detailed Description

It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict, and the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

In the embodiment of the present invention, if there is directional indication (such as upper, lower, left, right, front, and rear … …) only for explaining the relative position relationship between the components and the motion situation under a certain posture (as shown in the drawing), if the certain posture is changed, the directional indication is changed accordingly.

In addition, the descriptions of the first, second, etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 3, the spring clamp dismounting and mounting fixture for single tubes of an inverter of the present invention comprises 2 tooling plates 10, wherein each tooling plate 10 is square, a plurality of slots 11 are formed on one side of each tooling plate 10, the width of each slot 11 is matched with the width of each spring clamp 20, and the distance between each slot 11 corresponds to the distance between each single tube 30 of the inverter.

As an embodiment, the length L of the tooling plate 10 satisfies: l ═ L₁+L₂+n·F_n·L₂/F_h+L₄(ii) a Wherein n is the number of the slots 11 on the tooling plate 10, and F_nClamping force, F, provided for deformation of spring clamp 20_hForce for the hand to pinch the tooling plate 10, L₁Is the distance, L, from the point of action of the spring clamp 20 and the tooling plate 10 to the outer end of the tooling plate 10₂Distance L between the point of action of the spring clamp 20 on the tool plate 10 and the point of support of the spring clamp 20 on the tool plate 10₃Distance, L, from the point of application of force to the tooling plate 10 by a human hand to the point of support of the spring clamp 20 and the tooling plate 10₄Is the width of a human finger.

In one embodiment, the tooling plate 10 is made of a metal material (other materials with better strength and rigidity can be used).

The utility model discloses single tube of inverter's spring clamp dismouting anchor clamps's application method does: 1. the spring clamp 20 is placed into the clamping groove 11 of the tooling plate 10 (the spring clamp 20 is located between 2 tooling plates 10, and 2 tooling plates 10 act on the ear grooves on two sides of the spring clamp 20 respectively), and the clamping groove 11 on the tooling plate 10 is used for ensuring that the distance between each spring clamp 20 is matched with the distance between each single tube 30. 2. The other ends of the two tooling plates 10 of the spring clamp dismounting clamp for slightly pinching the single tube of the inverter open the spring clamp 20. 3. The spring clamp 20 is put into the assembly position, the spring clamp assembly and disassembly clamp of the inverter single tube is loosened, and the spring clamp 20 clamps the single tube 30.

The utility model discloses utilize lever principle ingeniously, under the prerequisite of assembling spring clamp 20 in batches, it is also very convenient to strut spring clamp 20 operation, and the power of holding between the fingers anchor clamps promptly is very little.

The clamping force F provided by the deformation of the spring clamp 20 is generally sufficient to allow a single tube to be securely clamped_nI.e. the force required to open the spring clamp 20 when assembling the spring clamp 20 is greater than F_n. If we assemble n spring clamps 20 at the same time, the force F of the spring machine needs to be expanded_t＝n·F_n。

As shown in fig. 2, the tooling plate 10 has a length L ═ L₁+L₂+L₃+L₄；

Force F of pinching the clamp according to the lever principle_h＝F_t·L₂/L₃＝n·F_n·L₂/L₃

Therefore, the length L of the tooling plate 10 is equal to L₁+L₂+n·F_n·L₂/F_h+L₄；

In general F_nAbout 60N, when assembling 6 spring clips 20 simultaneously, to ensure that the force holding the clips during assembly is within a normally acceptable range, define F_hIs 20. While depending on the design of the spring clip 20, L₁Is 5mm, L₂Is 12 m; considering ergonomics, the finger space L₄Taking 20 mm;

in this case, the length of the tooling plate 10 is L253 + 5+12+20+6 × 60 × 12/20.

As can be seen from the above, when different numbers of spring clips 20 are simultaneously assembled, the grooving of the tooling plate 10 and the length L of the tooling plate 10 may be adjusted.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
