Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a hole position detection mechanism for an engine end cover. Background Art

[0002] The engine is one of the important components of the car, among which the engine end cover is an important component in the engine structure. The engine end cover is usually processed with multiple holes in different positions. After the holes are processed, the positions of the holes usually need to be detected to ensure that the finished product of the engine end cover is qualified. The existing method for detecting the positions of the holes on the engine end cover is usually to use a three-coordinate measuring machine. The measurer uses the three-coordinate measuring machine to measure the positions of each hole on the engine end cover to determine whether the position and size of each hole on it meet the processing accuracy requirements of the drawing. However, due to the large number of holes on the engine end cover, this detection method is time-consuming, and the detection workload is large, and the detection efficiency is low. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an engine end cover hole position detection mechanism, which can detect whether the position of the hole is qualified by inserting a first measuring column into a corresponding first die hole and checking whether its lower end is inserted into the corresponding hole on the engine end cover, so as to quickly detect the position of the hole.

[0004] According to the engine end cover hole position detection mechanism described in the embodiment of the utility model, it includes a base, a detection template and a first measuring column.

If the lower end of the first measuring column cannot be inserted into the corresponding hole on the engine end cover, the lower end of the first measuring column will abut against the engine end cover, indicating that the position of the hole is offset and does not meet the design requirements. Therefore, by penetrating the corresponding first die hole of the first measuring column, whether the lower end of the first measuring column is inserted into the corresponding hole on the engine end cover can be used to detect whether the position of the hole is qualified. The structure is simple, and the position of the hole can be quickly detected, which is conducive to improving the detection efficiency and is easy to use.

[0031] Reference Figure 1 and Figure 2A mechanism for detecting the hole position of an engine end cover comprises a base 100, a detection template 200 and a first measuring column 310. The base 100 is provided with a positioning platform 110 for positioning and placing the engine end cover 1. The detection template 200 is detachably connected to the base 100 or movably connected to the base 100. The detection template 200 is provided with a first die hole 201. The first die hole 201 is provided with a plurality of holes and is arranged corresponding to the hole position distribution of the drawing design of the engine end cover 1. The first measuring column 310 is provided with a plurality of holes corresponding to the first die holes 201. When the engine end cover 1 is positioned and placed on the positioning platform 110, the detection template 200 can be placed above the engine end cover 1. The first measuring column 310 can penetrate the corresponding first die hole 201, so that the lower end of the first measuring column 310 is inserted into the corresponding hole of the engine end cover 1 or abuts against the engine end cover 1.

[0032] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when performing the inspection, the inspection template 200 is first moved away from the top of the positioning platform 110 to facilitate the positioning of the engine end cover 1 on the positioning platform 110; after the engine end cover 1 is placed, the inspection template 200 is placed on the top of the engine end cover 1, and then a plurality of first measuring columns 310 are respectively inserted into and penetrated through the corresponding plurality of first die holes 201. Since the plurality of first die holes 201 on the inspection template 200 correspond to the hole position distribution arrangement of the drawing design of the engine end cover 1, the insertion position of the first measuring column 310 is the design position of the hole on the engine end cover 1. If the lower end of the first measuring column 310 is inserted into the engine end cover 1, the first measuring column 310 is inserted into the engine end cover 1. If the first measuring column 310 is inserted into the corresponding hole on the engine end cover 1, it indicates that the position size of the hole meets the design requirements. If the lower end of the first measuring column 310 cannot be inserted into the corresponding hole on the engine end cover 1, the lower end of the first measuring column 310 will abut against the engine end cover 1, so that the first measuring column 310 is lifted up, indicating that the position of the hole is offset and does not meet the design requirements. Therefore, by passing the first measuring column 310 through the corresponding first mold hole 201, whether the lower end is inserted into the corresponding hole on the engine end cover 1 can be used to detect whether the position of the hole is qualified. The structure is simple, and the position of the hole can be quickly detected, which is beneficial to improving the detection efficiency and is easy to use.

[0033] In actual application, the specific number of the first mold holes 201 and the first measuring columns 310 can be set according to actual use needs and is not limited here.

[0034] In some embodiments, the detection template 200 is slidably connected to the base 100 and has a first position and a second position relative to the base 100. When the detection template 200 is at the first position, the detection template 200 is located above the positioning platform 110. When the detection template 200 is at the second position, the detection template 200 leaves the positioning platform 110.

[0035] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the detection template 200 is slidably connected to the base 100. When the detection template 200 slides to the second position relative to the base 100, the detection template 200 leaves the top of the positioning platform 110. At this time, the engine end cover 1 can be conveniently placed on the positioning platform 110; when the detection template 200 slides to the first position relative to the base 100, the detection template 200 is located above the positioning platform 110. At this time, the hole position of the engine end cover 1 below can be detected through the detection template 200. The structure is simple, and the position switching of the detection template 200 is convenient.

[0036] In actual application, in addition to the above structure, the detection template 200 can also be detachably connected to the base 100 through a snap-on structure or a threaded structure, or the detection template 200 can be rotatably connected to the base 100, which can be specifically set according to actual use needs.

[0037] Furthermore, the base 100 and / or the detection template 200 is provided with a handle 360, such as Figures 1 to 4 As shown, the base 100 and the detection template 200 are both provided with a handle 360. The design of the handle 360 ​​on the detection template 200 can facilitate the operation of moving the detection template 200, while the design of the handle 360 ​​on the base 100 can facilitate the movement and transportation of the base 100, making it easy to use. In actual application, the specific structure, number of settings, distribution position, etc. of the handle 360 ​​can be set accordingly according to actual use needs.

[0038] Furthermore, the first position is located in front of the second position, and the base 100 is provided with a slide rail 120 extending in the front-to-back direction. There are two slide rails 120 and they are respectively arranged on the left and right sides of the positioning platform 110. The left and right sides of the detection template 200 are provided with sliders 210 that cooperate with the slide rails 120.

[0039] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first position is the front position of the base 100, and the second position is the rear position of the base 100. Two slide rails 120 are respectively arranged on the left and right sides of the positioning platform 110, and the slide rails 120 extend forward and backward. The detection template 200 slides with the slide rails 120 through the slider 210, so that it can slide forward and backward relative to the base 100 to achieve the movement and switching between the first position and the second position. The structure is stable and reliable and easy to use. In actual application, the specific sliding mode of the detection template 200 can also be changed according to the actual use needs, such as through the cooperation of pulleys and slide grooves, etc., which will not be repeated here.

[0040] Furthermore, the front and rear sides of the slide rail 120 are both provided with limit blocks 121 , and the detection template 200 can move along the slide rail 120 until it abuts against the corresponding limit blocks 121 .

[0041] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each slide rail 120 is provided with a limit block 121 on the front and rear sides. By providing the limit block 121, when the detection template 200 moves to the first position, the front side of the detection template 200 abuts against the limit block 121 on the front side of the slide rail 120, and when the detection template 200 moves to the second position, the rear side of the detection template 200 abuts against the limit block 121 on the rear side of the slide rail 120, thereby limiting the front and rear sliding stroke of the detection template 200 and being able to provide a reminder of the detection template 200 being in place when it moves to the first position or the second position, which is convenient for use. In actual application, the specific structure of the limit block 121 can be set accordingly according to actual use needs.

[0042] Furthermore, a limiting structure is provided at the first position and / or the second position, and the limiting structure can limit the movement of the detection template 200 relative to the base 100 .

[0043] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, both the first position and the second position are provided with a limiting structure. By setting the limiting structure, when the detection template 200 moves to the first position, the limiting structure at the first position can be used to limit the movement of the detection template 200 relative to the base 100, so that it is fixed, which is convenient for subsequent detection and use; when the detection template 200 moves to the second position, the limiting structure at the second position can be used to limit the movement of the detection template 200 relative to the base 100, so that it is fixed, so as to prevent it from being damaged or lost when it is not used for detection, which is convenient for use. In actual application, the limiting structure can also be set only at the first position or the second position, which can be set accordingly according to actual use needs.

[0044] Specifically, the limiting structure includes a limiting seat 140 and a limiting pin 340 . The limiting seat 140 is fixed on the base 100 , and the limiting pin 340 can penetrate the detection template 200 and be inserted into the limiting seat 140 .

[0045] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, two limit seats 140 are provided and respectively correspond to the first position and the second position, and two limit pins 340 are provided accordingly. When the detection template 200 moves to the first position or the second position and needs to be locked, the limit pins 340 can be used to penetrate the detection template 200 and insert it into the limit seat 140, thereby limiting its forward and backward movement. The structure is simple and easy to use. In actual application, in addition to the above structure, the limit structure can also be achieved by magnetic attraction, clamping or threaded connection to fix the detection template 200 relative to the base 100, which can be set accordingly according to actual use needs.

[0046] In some embodiments, the engine end cover hole position detection mechanism also includes a second measuring column 320, and a second mold hole 101 is provided on the positioning platform 110. The second mold hole 101 is provided with multiple holes and the hole position distribution arrangement corresponds to the drawing design of the engine end cover 1. When the engine end cover 1 is positioned and placed on the positioning platform 110, the second measuring column 320 can penetrate the corresponding hole on the engine end cover 1, so that the lower end of the second measuring column 320 can be inserted into the corresponding second mold hole 101 or abut against the positioning platform 110.

[0047] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning platform 110 is provided with a plurality of second die holes 101, and the plurality of second die holes 101 are also arranged according to the hole position distribution design of the drawing of the engine end cover 1. By setting the second measuring column 320 and the second die hole 101, during the inspection, the second measuring column 320 can be inserted into the corresponding hole on the engine end cover 1, which is similar to the inspection principle of the first measuring column 310. If the lower end of the second measuring column 320 is inserted into the corresponding second die hole 101, it indicates that the position size of the hole it is inserted into meets the design requirements. If the lower end of the second measuring column 320 cannot be inserted into the corresponding second die hole 101, the lower end of the second measuring column 320 will abut against the positioning platform 110, so that the second measuring column 320 is lifted up, indicating that the position of the hole it is inserted into is offset and does not meet the design requirements. Whether the lower end of the second measuring column 320 is inserted into the corresponding second die hole 101 can be used to detect whether the position of the hole it is inserted into is qualified, and the detection of holes that cannot be covered or are difficult to detect by the inspection template 200 is supplemented, which is convenient for use.

[0048] In actual application, the specific number of the second mold holes 101 and the second measuring columns 320 can be set according to actual use needs and is not limited here.

[0049] In some embodiments, the engine end cover hole position detection mechanism also includes a third measuring column 330. A detection platform 130 is provided on the base 100. The detection platform 130 is located on the side of the positioning platform 110. The third measuring column 330 is movably inserted into the detection platform 130. When the engine end cover 1 is positioned on the positioning platform 110, the end of the third measuring column 330 can be inserted into the corresponding hole on the side of the engine end cover 1 or abut against the engine end cover 1.

[0050] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a plurality of inspection platforms 130 are provided on the side of the positioning platform 110, and the plurality of inspection platforms 130 are respectively arranged according to the hole positions designed in the drawing of the side of the engine end cover 1. During the inspection, similar to the inspection principle of the first measuring column 310, if the end of the third measuring column 330 can be inserted into the corresponding hole on the side of the engine end cover 1, it indicates that the position size of the hole meets the design requirements. Otherwise, the end of the third measuring column 330 abuts against the engine end cover 1, and the position size of the hole does not meet the design requirements. Whether the end of the third measuring column 330 can be inserted into the corresponding hole on the side of the engine end cover 1 is used to detect whether the position of the hole is qualified, and the inspection of the hole on the side of the engine end cover 1 is supplemented for easy use.

[0051] In actual application, the specific number of the detection platform 130 and the third measurement column 330 can be set according to actual use needs, and is not limited here.

[0052] In some embodiments, the positioning platform 110 is provided with a positioning portion 111 for positioning the placement of the engine end cover 1. It is understandable that Figure 2 and Figure 4 As shown, by providing the positioning portion 111, it is convenient to position the engine end cover 1 on the positioning platform 110, and the structure is simple and easy to use. In actual application, the structure used for positioning on the positioning platform 110 can also be a groove, a contoured surface, etc., which can be set accordingly according to actual use needs.

[0053] In some embodiments, a locking pin 350 is provided on the positioning platform 110 . When the engine end cover 1 is positioned on the positioning platform 110 , the locking pin 350 can penetrate the engine end cover 1 and connect to the positioning platform 110 to limit the movement of the engine end cover 1 relative to the positioning platform 110 .

[0054] It is understandable that if Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, there are multiple locking pins 350. When the engine end cover 1 is positioned and placed on the positioning platform 110, the locking pins 350 penetrate the engine end cover 1 and connect to the positioning platform 110, thereby limiting the movement of the engine end cover 1 relative to the positioning platform 110, so as to avoid the displacement of the engine end cover 1 during the detection process, which is convenient for detection. In actual application, the locking pins 350 can be threaded parts or latches, and the specific number and distribution positions of the locking pins can be set accordingly according to actual use needs.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
