[0035] When measuring the depth of the upper cylinder bore of the cylinder block, in order to quickly and accurately measure the depth of the upper cylinder bore of the cylinder block and facilitate the measurement operation, as Figure 1 - Figure 2 shown, the present invention provides a device for detecting the depth of the upper cylinder bore of the cylinder block. The device for detecting the depth of the upper cylinder bore of the cylinder block includes a checking body 1, a measuring assembly 2, and a positioning assembly 3.

[0036] Among them, the lower end surface of the checking body 1 is a plane, and the checking body 1 can be placed on the upper end surface of the cylinder block. The measuring assembly 2 includes a micrometer 21, a gauge body 22, and a measuring rod 23. The gauge body 22 is arranged on the checking body 1 and is perpendicular to the checking body 1. The measuring rod 23 is inserted into the gauge body 22, and the measuring rod 23 can move along the axial direction of the gauge body 22, so that the measuring end 232 of the measuring rod 23 can extend relative to the gauge body 22 to detect the depth of the upper cylinder bore. The micrometer 21 is arranged at one end of the gauge body 22 away from the checking body 1, and the head of the micrometer 21 abuts against the measuring rod 23. The positioning assembly 3 is arranged on the checking body 1 and is used to limit the position of the checking body 1 relative to the upper cylinder bore.

[0037] When measuring the depth of the upper cylinder bore of the cylinder block, the checking body 1 is placed on the cylinder block, and the positioning assembly 3 limits the position of the checking body 1 relative to the upper cylinder bore. Control the measuring rod 23 to extend relative to the gauge body 22 until it reaches the root of the upper cylinder bore, and then read the data of the micrometer 21. Since the lower end surface of the checking body 1 is a plane and the gauge body 22 is perpendicular to the checking body 1, after the checking body 1 is placed on the cylinder block, the measuring rod 23 inserted into the gauge body 22 is coaxial with the upper cylinder bore, and the position of the checking body 1 is limited by the positioning assembly 3, which can prevent the measuring rod 23 from tilting relative to the upper cylinder bore. Through the above settings, the depth of the upper cylinder bore can be measured at the production site, and the depth of the upper cylinder bore of the cylinder block can be quickly and accurately measured, which is convenient for the measurement operation.

[0038] In some embodiments, the upper cylinder bore depth detection device of the cylinder block further includes a locking assembly 4. The locking assembly 4 includes a dial gauge sleeve 41, a locking block 42, and a screw 43. One end of the dial gauge sleeve 41 is connected to the end of the gauge body 22 away from the inspection body 1. The micrometer 21 is inserted into the dial gauge sleeve 41. The locking block 42 is arranged on the micrometer 21. The other end of the dial gauge sleeve 41 is inserted into the locking block 42. The screw 43 is inserted into the locking block 42. By screwing the screw 43, the locking block 42 can hold the dial gauge sleeve 41 tightly. Specifically, a gauge sleeve 211 is sleeved on the micrometer 21, and the gauge sleeve 211 is used to protect the micrometer 21. The locking block 42 is fixedly arranged on the gauge sleeve 211. A locking hole and an opening communicating with the locking hole are formed in the locking block 42. The dial gauge sleeve 41 is inserted into the locking hole. By screwing the screw 43, the opening is reduced, and the locking block 42 holds the dial gauge sleeve 41 tightly through the locking hole, so as to install the micrometer 21 on the gauge body 22.

[0039] In some embodiments, a spiral groove 222 is formed in the gauge body 22. The operating handle 231 is inserted into the spiral groove 222, and one end of the operating handle 231 is connected to the measuring rod 23. Through the above arrangement, the measuring rod 23 can be driven to move by the operating handle 231, and the spiral groove 222 plays a guiding role. When the operating handle 231 moves upward along the spiral groove 222, the measuring rod 23 retracts relative to the gauge body 22. When the operating handle 231 moves downward along the spiral groove 222, the measuring rod 23 extends relative to the gauge body 22 for measurement.

[0040] In some embodiments, a threaded hole is formed in the measuring rod 23, and one end of the operating handle 231 is screwed into the threaded hole. By adopting the threaded connection method to install the operating handle 231, it is convenient to realize the quick assembly of the operating handle 231 and the measuring rod 23.

[0041] In some embodiments, a positioning hole is formed in the inspection body 1. A positioning plate is fixedly arranged on the outer peripheral surface of the gauge body 22. The first end of the gauge body 22 is inserted into the positioning hole, and the positioning plate is attached to the inspection body 1. The fastener passes through the positioning plate and is connected to the inspection body 1. Specifically, a first mounting hole is formed in the positioning plate, and a second mounting hole opposite to the first mounting hole is formed in the inspection body 1. The fastener is a bolt, and the fastener passes through the first mounting hole and is connected to the second mounting hole. By adopting the above method, it is convenient to quickly fix the gauge body 22 on the inspection body 1, and it can ensure that the gauge body 22 and the inspection body 1 maintain a perpendicular relationship.

[0042] In some embodiments, the measuring end 232 of the measuring rod 23 has an abutting protrusion, the first end of the gauge body 22 is provided with a guide ring groove 221, and an elastic member 7 is sleeved on the measuring rod 23, one end of the elastic member 7 is abutted against the abutting protrusion, and the other end of the elastic member 7 is abutted against the groove bottom of the guide ring groove 221. In this embodiment, the elastic member 7 is a compression spring. By providing the compression spring, the measuring end 232 of the measuring rod 23 maintains a tendency to extend relative to the gauge body 22. When measuring the depth of the upper cylinder hole, the elastic member 7 pushes the measuring end 232 of the measuring rod 23 to extend into the upper cylinder hole as far as possible until it reaches the root of the upper cylinder hole. Through the above arrangement, the depth of the upper cylinder hole can be accurately measured. By providing the guide ring groove 221, the elastic member 7 can be accommodated, and when the measuring rod 23 retracts relative to the gauge body 22, the movement of the measuring rod 23 can be guided and the abutting protrusion can be accommodated.

[0043] In some embodiments, the positioning assembly 3 includes four limit blocks 31, which are arranged at intervals on the inspection body 1, and the limit blocks 31 can fit with the hole wall of the upper cylinder hole. Specifically, in this embodiment, the circumference of the four limit blocks 31 is an arc surface, and the four limit blocks 31 are located on the same circle, and the diameter of the circle is 0.2mm-0.5mm smaller than the diameter of the upper cylinder hole. When measuring the depth of the upper cylinder hole, the limit blocks 31 can limit the position of the inspection body 1 relative to the upper cylinder hole, so as to quickly achieve preliminary positioning.

[0044] In some embodiments, the cylinder block upper cylinder hole depth detection device further includes an abutment assembly 5, the abutment assembly 5 includes a rotating plate 51 and an elastic cam 52, the rotating plate 51 is rotatably arranged on the detection body 1, the elastic cam 52 is arranged on the rotating plate 51, the rotating plate 51 has an abutment position and a release position, when the rotating plate 51 is in the abutment position, the elastic cam 52 abuts against the hole wall of the upper cylinder hole, so that the measuring rod 23 fits against the hole wall of the upper cylinder hole. When measuring the depth of the upper cylinder hole, the rotating plate 51 rotates to the abutment position, and the elastic cam 52 abuts against the hole wall of the upper cylinder hole. Since the elastic cam 52 is elastically deformed, the measuring rod 23 fits against the hole wall of the upper cylinder hole under the action of the elastic deformation restoring force, thereby ensuring that the measuring rod 23 can effectively measure the root of the upper cylinder hole. In order to facilitate the operation of the rotating plate 51, a lever 53 is arranged on the rotating plate 51. By pulling the lever 53, the rotating plate 51 can be driven to switch between the abutment position and the release position.

[0045] In some embodiments, a shift handle 6 is fixedly provided on the inspection body 1. By providing the shift handle 6, it is convenient for inspectors to use the cylinder hole depth detection device on the cylinder block in a turnover manner.

[0046] In some embodiments, the cylinder block upper cylinder bore depth detection device further includes a wireless transmitter 8, and the wireless transmitter is communicatively connected to the dial indicator 21 and the data acquisition device. By providing the wireless transmitter 8, it is convenient to collect data.

[0047] This application also provides a usage method, which uses the above-mentioned cylinder block upper cylinder bore depth detection device to measure the depth of the upper cylinder bore of the cylinder block, and includes the following steps:

[0050] S3. Control the measuring rod 23 to extend relative to the gauge body 22 until it reaches the root of the upper cylinder bore, and read the data of the dial indicator 21.
