[0002] A door closer is a commonly used device in door systems, and the machining accuracy of its housing has an important impact on the performance of the door closer. For a door closer housing with horizontally and vertically symmetric holes, accurately detecting the center distance between the horizontal hole and the end of the door closer housing is a key link to ensure product quality. Traditional detection methods usually use general measuring tools, such as calipers, micrometers, etc. for measurement. However, these general measuring tools have many deficiencies in detecting the center distance of horizontal and vertical holes: on the one hand, due to the structural characteristics of the horizontal and vertical holes, it is difficult for general measuring tools to accurately locate the measurement reference, resulting in large measurement errors; on the other hand, the measurement efficiency of general measuring tools is low, and it is difficult to meet the rapid detection requirements in large-scale production processes. Therefore, the present invention provides a detection device for door closer housings to solve the above problems. Summary of the Invention

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the drawings.

[0029] Embodiment 1:

[0030] Please refer to Figures 1-7, A door closer housing detection device, including a carrier table 1 for carrying the door closer housing 2. A central hole 21 is provided on the side of the door closer housing 2. On both sides of the top of the carrier table 1, loading grooves 3 adapted to the door closer housing 2 are symmetrically provided. An auxiliary unit for position correction and positioning of the door closer housing 2 is provided on the carrier table 1;

[0031] On both sides of the carrier table 1, convex strips 31 are symmetrically provided. Circular grooves are provided at both ends of the convex strips 31. An active rod 32 is slidably connected to the inner side of the circular groove. A connecting spring 33 is fixedly connected between the active rod 32 and the inner wall of the circular groove. A square rod 34 is fixedly connected between the active rods 32 on both sides of the same end. A moving block 35 is slidably connected to the surface of the square rod 34. Positioning columns 36 are threadedly connected to the opposite sides of the two moving blocks 35. Scale lines 37 are provided along the axial direction of the square rod 34 on both sides of the top of the carrier table 1. Transparent plates 38 are provided on the opposite sides of the two moving blocks 35 away from each other. An indicating arrow 39 is provided on the transparent plate 38.

[0032] It should be noted that the shape and dimensional specifications of the positioning column 36 are adapted to the central hole 21, so that during the detection process, the positioning column 36 can be inserted into the interior of the central hole 21 and can be concentric with the central hole 21 after entering the interior of the central hole 21.

[0033] Furthermore, the scale line 37 is coaxially arranged with the axial symmetry axis of the square rod 34, that is, when the hole position of the central hole 21 on the door closer housing 2 is accurate, the axial center point of the square rod 34, the center point of the scale line 37, and the center point of the door closer housing 2 after position correction can be in the same vertical plane.

[0034] In this embodiment, the transparent plate 38 is a convex lens, and the position height of the transparent plate 38 is adapted to the scale line 37, so that under the magnifying effect of the transparent plate 38, the operator can more clearly see the scale position indicated by the indicating arrow 39, thereby facilitating the operator to judge the accuracy of the central hole 21.

[0035] In this embodiment, the auxiliary unit includes a guide groove 4 opened at the top of the carrier 1. At both ends of the inner side surface of the guide groove 4, correction plates 41 are symmetrically and slidably connected. At the bottom of the guide groove 4, a mating gear 42 is rotatably connected. At the bottom of both correction plates 41, transmission racks 43 are fixedly connected. The two transmission racks 43 are respectively engaged at both ends of the mating gear 42. On the inner side surface of one correction plate 41, a vertical groove 44 is opened. In the inner side surface of the vertical groove 44, a pressing block 45 is slidably connected. Between the top of the pressing block 45 and the inner wall of the vertical groove 44, a pressing spring 46 is fixedly connected. At the bottom of the pressing block 45, a number of positioning bars 47 are equidistantly arranged. Along the moving direction of the correction plate 41 on the top of the carrier 1, a number of positioning grooves 48 adapted to the positioning bars 47 are equidistantly arranged. On the surface of the correction plate 41, a lifting groove 49 communicating with the vertical groove 44 is opened. In the inner side surface of the lifting groove 49, a lifting bar 410 is slidably connected. The lifting bar 410 is fixedly connected to the pressing block 45.

[0036] In this embodiment, a guide rod 411 is fixedly connected to the inner side surface of the guide groove 4. The correction plate 41 is slidably connected to the outer side surface of the guide rod 411. And between the opposite side surfaces of the two correction plates 41 and the inner wall of the guide groove 4, a return spring 412 is fixedly connected.

[0037] When measuring the closer housing 2, the operator places the two closer housings 2 in the bearing grooves 3 on both sides. Then the operator pulls up the lifting bar 410 upward, so that the pressing block 45 moves upward and drives the positioning bar 47 to move upward, separating it from the surface of the carrier 1. Subsequently, the operator pushes the correction plate 41 on this side to move. The movement of the correction plate 41 drives the transmission rack 43 at its bottom to move. Under the cooperation of the mating gear 42 and the transmission rack 43, the other correction plate 41 can perform a synchronous reverse movement, so that the two correction plates 41 move closer synchronously and correct the position of the closer housing 2. When both correction plates 41 are in contact with the closer housing 2, the operator releases the lifting bar 410. At this time, under the action of the resilience of the pressing spring 46, the pressing block 45 moves downward and drives the positioning bar 47 at its bottom to insert into the positioning groove 48 on the carrier 1, restricting the position of the correction plate 41 and preventing it from continuing to move;

[0038] When the position of the closer housing 2 is corrected and positioned, the operator manually moves the two moving blocks 35 on both sides and inserts the positioning posts 36 outside them into the central holes 21 on the two closer housings 2 on both sides. At this time, the operator can directly judge whether the center distance of the central hole 21 meets the specified value according to the scale line 37 indicated by the indication arrow 39, so as to ensure the accuracy and quality of the closer housing 2.

[0039] Embodiment 2:

[0040] Please refer to Figure 3, this embodiment provides a technical solution based on the above embodiment: a retaining piece 5 is fixedly connected to one side of the square rod 34, and a positioning spring 51 is fixedly connected between the retaining piece 5 and the moving block 35. The positioning spring 51 is sleeved outside the square rod 34, and the inner diameter value of the positioning spring 51 is greater than the outer diameter value of the square rod 34, so that the normal compression or stretching of the positioning spring 51 will not be affected.

[0041] When not working, with the cooperation of the positioning spring 51, the moving block 35 can always be kept in a stable state, thus ensuring the stability of the entire inspection tool.

[0042] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
