[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present utility model, it should be noted that the terms "upper", "middle", "lower", "inside", "outside", "front", "back", "left", "right" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0031] See also Figure 1 to Figure 2 The utility model discloses a positioning assembly jig, which comprises:

[0032] Base 1;

[0033] A positioning groove, wherein the positioning groove is formed by an inward depression of one side end surface of the base 1; the positioning groove comprises at least two interconnected groove bodies;

[0034] The clamping mechanism includes a pressing plate 3, which is rotatably connected to the base 1. The pressing plate 3 can rotate relative to the base 1 to press on the parts carried in the slot body.

[0035] By means of the above structure, the positioning groove includes at least two interconnected groove bodies for placing parts to be assembled (such as hydraulic cylinder parts). When assembling hydraulic cylinder parts, first place the parts in the corresponding groove bodies, and then operate the clamping mechanism to make the pressure plate 3 included in it rotate relative to the base 1, so that the pressure plate 3 is pressed onto the parts carried by the groove body, and stably clamps the parts with the groove body to ensure that the parts do not shift during the alignment and assembly process, making assembly more convenient, ensuring assembly quality, and improving assembly efficiency.

[0036] See also Figure 1 and Figure 2 Specifically, in this embodiment, the positioning groove is formed by the upper end surface of the base 1 being recessed downward, and includes a first groove body 21 and a second groove body 22. The first groove body 21 extends in the left-right direction, and its cross section is generally in a deformed "V" shape. The second groove body 22 extends in the front-back direction and is generally in a rectangular shape. The middle front side of the first groove body 21 is connected to the rear end of the second groove body 22 to carry parts of corresponding shapes respectively. Of course, in other embodiments, the first groove body 21 and the second groove body 22 can also be set to other shapes according to the actual needs of the parts to be assembled, such as "T" shape, "L" shape, arc shape, etc.

[0037] Specifically, in this embodiment, a pin hole is provided on the bottom wall of the groove near the right end of the first groove body 21, which can be plugged and unplugged with a positioning pin 4. When the bottom end of the positioning pin 4 is inserted into the bottom of the pin hole (the pin hole is a blind hole), the extension portion of the upper end thereof protrudes from the first groove body 21. More specifically, the positioning pin 4 and the pin hole are provided to position the part with a hole placed in the first groove body 21, that is, after the part with a hole is placed in the first groove body 21 accordingly, the positioning pin 4 is used to pass through the hole of the part from top to bottom, and then penetrate into the pin hole, so that the part will not be relatively displaced with the first groove body 21 in the left and right directions and can be effectively limited. It should be understood that when the positioning pin 4 passes through the hole of the part and is inserted into the pin hole, the extension portion of the positioning pin 4 should protrude from the upper end surface of the part, so as to facilitate its plugging and unplugging. Preferably, in this embodiment, the positioning pin 4 is clearance-matched with the pin hole.

[0038] See also Figure 1Specifically, in the present embodiment, the front end of the second slot body 22 is detachably connected to a clamping plate 5. If the parts placed in the second slot body 22 only need to be positioned in the left and right directions, the clamping plate 5 can be directly removed. If there are multiple specifications in the front and rear directions, fasteners of different lengths can be selected according to their specific specifications to fasten the clamping plate 5 to the front end of the second slot body 22, thereby making the second slot body 22 more adaptable.

[0039] See also Figure 2 Specifically, in this embodiment, the positioning assembly jig further includes a first pressure sensor 61 and a second pressure sensor 62; wherein, in this embodiment, since the pressing plate 3 will simultaneously press the parts in the first slot body 21 and the second slot body 22 when pressing down, a total of three first pressure sensors 61 are provided at the bottom of the first slot body 21 and the second slot body 22, so that the sensing part thereof can monitor the pressure of each point of the parts given by the pressing plate 3 at the bottom of the two slot bodies, and the sensing part of the second pressure sensor 62 is provided at the side of the first slot body 21 opposite to the clamping plate 5 to monitor the holding force of the parts given by the clamping plate 5 in the front-rear direction. Of course, in other embodiments, if it is only necessary to press the pressing plate 3 down to hold the parts in the first slot body 21 or the second slot body 22, only one first pressure sensor 61 may be provided accordingly.

[0040] Please continue reading Figure 1 and 2 Specifically, in this embodiment, the clamping mechanism includes a pressing plate 3 which is rotatably connected to one side of the positioning groove through a clamp, and the model of the clamp is GH-12265. More specifically, the clamp includes a base 71, a pressing handle 72 and a handle 73; wherein the base 71 is fixedly arranged on one side of the positioning groove; the rear end of the pressing handle 72 is hinged to the base 71, and the front end is fastened to the pressing plate 3; the lower end of the handle 73 is hinged to the base 71 to drive the pressing handle 72 to swing, so as to drive the pressing plate 3 to rotate relative to the base 1 with the base 71 as the center and the pressing handle 72 as the radius, and can be pressed down onto the part carried by the positioning groove, and cooperate with the positioning groove in the vertical direction to limit the part. Preferably, the pressing handle 72 is "U"-shaped, and its open end is hinged to the base 71. The pressing plate 3 is fastened to the "U"-shaped groove of the pressing handle 72 by a fastening assembly. The bolt members arranged along the vertical direction in the fastening assembly can be moved in the "U"-shaped groove along the front-rear direction and then fastened in place using nuts, so that the pressing position of the pressing plate 3 can be adjusted to the optimal level.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not limited to the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
