Technical Field

[0001] The utility model relates to the technical field of electric pedals, in particular to a screw tightening tool for an end cover of an electric pedal. Background Art

[0002] The electric step is an automatic retractable device installed on the side of the car, mainly used to assist passengers in getting on and off the car. The electric step is a narrow strip with a hollow structure inside. End caps are installed at the front and rear ends. The shape of the end caps is as follows: Figure 7 and Figure 8 As shown, the width of the end cover 4 is relatively small, usually only about 6 cm, and the side of the end cover 4 is surrounded by two planes (a first plane 404 and a second plane 405, the first plane 404 is the long side, and the second plane 405 is the short side of the end face) and an arc surface (the first arc surface 403), and the bottom surface and the side surface are transitioned into an arc. There are two screw fixing positions 402 on the top of the end cover 4 (near the corners of the first arc surface 403 and the second plane 405), and the screws need to be installed when assembling the end cover assembly. The two screws are usually manually tightened using an electric screwdriver.

[0003] The traditional method is to hold the end cover with one hand and use the other hand to hold an electric screwdriver to tighten the screws. However, due to the small width of the end cover, the arc-shaped transition between the bottom and the side, and the screw fixing position is close to the corner, the end cover is prone to tilt when tightening the screws, causing the screws to be skewed, resulting in unqualified assembly and low assembly efficiency. Utility Model Content

[0006] Furthermore, two sinking grooves and two pressure covers cooperating therewith are symmetrically arranged on the base.

[0007] Furthermore, the second arc surface in each accommodating cavity is located outside the third plane.

[0008] Furthermore, the notch extends to the edge where the second arc-shaped surface is located and the edge where the opening end is located, so that the notch forms an L-shaped structure at the top corner of the gland.

[0009] Furthermore, a marking pen is fixed on the upper surface of the base between the two pressure covers.

[0010] Furthermore, the pen cap of the marking pen is fixed to the base.

[0011] Furthermore, an anti-wear cloth is fixed to the inner bottom surface of the sinking trough.

[0012] Furthermore, the second arc-shaped surface and an end of the third plane away from the opening end are connected to each other.

[0013] Furthermore, the second arc-shaped surface and the third plane are spaced apart from one end of the opening end, and a cleaning port is formed therebetween, wherein the width of the cleaning port is smaller than the width of the end cover.

[0014] Furthermore, a threaded hole is provided on the top of the base, and the pressure cover has a plurality of countersunk holes which pass through the top and bottom, and locking screws pass through the countersunk holes and are fixed to the threaded holes.

[0015] Furthermore, the base and the upper cover are made of plastic material.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Embodiment 1

[0032] like Figure 1-Figure 5 As shown, a screw tightening tool for an electric pedal end cover comprises a base 1 and a pressure cover 2, the pressure cover 2 is fixed on the top of the base 1, the top of the base 1 has a sinking groove 3 for placing the end cover 4, the inner bottom surface 101 of the sinking groove 3 is in contact with the bottom surface 401 of the end cover 4, and the height of the sinking groove 3 is less than the height of the screw fixing position 402 on the end cover 4. After the end cover 4 is placed, the screw fixing position 402 faces upward, and the height of the sinking groove 3 is small, which will not block the screw fixing position 402.

[0033] The bottom of the gland 2 has a groove 5 that cooperates with the sinking groove 3 to form a receiving chamber 6. The inner side of the receiving chamber 6 includes a second curved surface 601 and a third plane 602 that contact the side of the end cover 4, and an open end 603 is formed at one end of the receiving chamber 6. The second curved surface 601 is opposite to the first curved surface 403 of the end cover 4, and the third plane 602 is opposite to the first plane 404 of the end cover 4. The end cover 4 is placed in the receiving chamber 6 by the open end 603 of the receiving chamber 6; the second curved surface 601 and the end of the third plane 602 away from the open end 603 are connected to each other, and the end cover 4 can be blocked from the rear end. The gland 2 has a notch 7 that exposes the screw fixing position 402, and the electric screwdriver can tighten the screw vertically downward through the notch 7.

[0034] The base 1 and the gland 2 are arranged separately, and there is no need to process the hole structure, which reduces the processing difficulty. Figure 4 As shown, a threaded hole 102 is provided on the top of the base 1 , and the gland 2 has a plurality of countersunk holes 201 extending vertically therethrough, and the locking screws 11 pass through the countersunk holes 201 and are fixed to the threaded holes 102 .

[0035] The base 1 and the pressure cover 2 can be made of plastic material. The plastic material is light in weight and the tooling is small in size, so it is very convenient to move at any time, and to a certain extent, it also avoids safety accidents that may be caused by falling.

[0036] The tooling of the utility model contacts the first curved surface and the first plane 404 of the end cover 4 to fix the end cover 4, limiting the five degrees of freedom of the end cover 4, which are the rotational degrees of freedom in three directions and the translational degrees of freedom in two directions (such as Fig. 9 As shown), the end cover 4 can be well fixed so that the end cover 4 will not rotate or move left and right, effectively preventing the end cover 4 from position deviation when tightening the screws, thereby reducing the defective rate of the electric pedal, and at the same time freeing one hand of the staff to improve work efficiency.

[0037] In addition, since the present invention can cover the rest of the end cover 4, it can to a certain extent avoid the situation where screws or foreign objects fall into the end cover 4 when the screws are installed in the assembly of the electric pedal end cover 4.

[0038] The notch 7 can be a hole that passes through the gland 2 from top to bottom, ensuring that the electric screwdriver can be inserted for operation. The utility model preferably adopts the following structure, such as Figure 1 As shown, the notch 7 extends to the side where the second arc surface 601 is located and the side where the opening end 603 is located, so that the notch 7 forms an L-shaped structure at the top corner of the gland 2. At this time, the gland 2 is easier to process and there is more operating space when tightening the screws.

[0039] Embodiment 2

[0040] One electric pedal is equipped with two end covers 4, so that two sets of end covers 4 of one electric pedal can be placed on one tool for processing, ensuring the synchronization of the process and avoiding misassembly. Therefore, in this embodiment, two sinking grooves 3 and two glands 2 that match them are symmetrically arranged on the base 1. When in use, after the tool is placed on a flat table, the front and rear end covers 4 of the electric pedal are placed in two accommodating chambers 6 respectively, and two end covers 4 of a set of electric pedals can be fixed at one time.

[0041] For ease of operation, Figure 5 As shown, the second arc surface 601 in each accommodating cavity 6 is preferably located outside the third plane 602. At this time, the screw fixing positions 402 of the two end covers 4 are also located outside, so that the operating space is larger.

[0042] Embodiment 3

[0043] On the basis of the above embodiment, a marking pen 8 is fixed on the upper surface of the base 1 between the two pressure covers 2. Figure 3 shown.

[0044] When installing the utility model, the end cover 4 is first placed in the accommodating cavity 6, and then a screw is placed in each screw hole. Since the screws are small in size, it is difficult to see with the naked eye whether they are tightened, so a marking pen 8 can be used to mark the tightened screws.

[0045] The pen cap of the marking pen 8 can be fixed to the base 1, and the marking pen 8 is in a vertical position for easy taking.

[0046] Embodiment 4

[0047] On the basis of the above-mentioned embodiment, the inner bottom surface 101 of the sinking tank 3 is fixed with an anti-wear cloth 9 (such as Figure 4 As shown). The inner surface of the sinking groove 3 contacts the bottom surface 401 of the end cover 4. During the process of tightening the screws, the bottom surface 401 is subjected to greater friction than the side surface, which can easily scratch the surface of the end cover 4. The anti-wear cloth 9 can protect the surface of the end cover 4.

[0048] Embodiment 5

[0049] The second arc surface 601 and the third plane 602 are spaced apart from one end of the opening end 603, and a cleaning port 10 (such as Figure 6As shown in the figure, the width of the cleaning port 10 is smaller than that of the end cover 4. Since the accommodating chamber 6 is relatively narrow and has a certain depth, it is difficult to reach in for cleaning. After a long period of dust accumulation in the workshop, the inner surface of the accommodating chamber 6 will be uneven, affecting the fixing effect of the end cover 4. The cleaning port 10 allows the accommodating chamber 6 to be connected from front to back. A spray gun can be used to spray the inside of the accommodating chamber 6 from one end, and impurities can be blown out from the other end. The arc structure of the second arc surface 601 helps the impurities move toward the cleaning port 10. The width of the cleaning port 10 is limited so that the accommodating chamber 6 can block the rear end surface of the end cover 4 to ensure the limit of the five degrees of freedom of the end cover 4.
