Description

Technical Field

[0001] This utility model relates to the field of test components, specifically an engine connecting rod test component with heat dissipation function. Background Technology

[0002] During engine production, the connecting rod of the engine needs to undergo tensile and vibration testing. Various testing devices have been proposed in the existing technology. This fixture utilizes the existing tensile testing machine and combines it with a vibration device to design a testing fixture structure that matches the engine connecting rod. With the tensile and vibration testing device, the engine connecting rod can be fixed and tested directly through the transmission principle.

[0003] The existing testing procedure involves fixing both ends of the engine connecting rod to two loading components. The hydraulic cylinder retracts to pull the sliding table, stretching the connecting rod. Simultaneously, a tension sensor measures the tension, performing a tensile test on the connecting rod. After the tensile test is completed, the hydraulic cylinder is released, and the drive mechanism is activated. The drive mechanism drives the two loading components to twist and vibrate laterally, thus performing a vibration test on the connecting rod. This vibration method is more complex, the vibration effect is better, and it enables torsional vibration testing of the connecting rod, resulting in more comprehensive test results.

[0004] However, the reciprocating motion of existing testing devices during operation converts kinetic energy into heat energy, which remains on the surface and inside of the testing device, causing the temperature of the testing device to rise and affecting the subsequent operational stability of the testing device. However, existing heat dissipation equipment uses external fixed-point fans to blow air onto the testing device to dissipate heat, which cannot cover all surfaces of the testing device and reduces the heat dissipation effect. Utility Model Content

[0005] The purpose of this utility model is to provide an engine connecting rod test assembly with heat dissipation function, which solves the problem that in the existing test device, the reciprocating motion during operation converts kinetic energy into heat energy that remains on the surface and inside of the test device, causing the temperature of the test device body to rise and affecting the subsequent operational stability of the test device. However, the existing heat dissipation equipment uses an external fixed-point fan to blow air to the test device to dissipate heat, which cannot cover all surfaces of the test device and reduces the heat dissipation effect.

[0006] Therefore, this utility model provides an engine connecting rod test assembly with heat dissipation function, including a base, a moving mechanism and a heat dissipation mechanism. The base is provided with a moving mechanism for adjusting the position of the heat dissipation assembly on the front and rear sides. A top frame is installed on the upper end of the moving mechanism. A heat dissipation mechanism for separate disassembly and maintenance is provided on the upper end of the top frame. A test push rod for testing engine connecting rod vibration is provided on the upper side of the center of the base.

[0007] Preferably, the moving mechanism includes a slide groove, a slide plate is installed in the slide groove, limit grooves are opened on the upper and lower sides of the slide groove, limit plates are installed on the upper and lower sides of the slide plate, a gear is installed on the rear side wall of the slide plate, a motor is connected to the side wall of the gear, a side groove is opened on the rear side of the slide groove, and a toothed plate is installed in the side groove.

[0008] Preferably, the heat dissipation mechanism includes a slot, a socket is inserted into the slot, an inner groove is formed on the side wall of the socket, an inner plate is installed in the inner groove, a retaining plate is installed at the lower end of the inner plate, a retaining groove is formed on the side wall of the slot, a hydraulic rod is installed inside the upper end of the inner groove, a spring is fitted on the outer wall of the hydraulic rod, a pressure plate is fitted on the outer wall of the spring, and an air outlet device is installed at the right end of the socket.

[0009] Preferably, the cross-sectional dimensions of the limiting groove match the cross-sectional dimensions of the limiting plate.

[0010] Preferably, the gear meshes with the toothed plate.

[0011] Preferably, the cross-sectional dimensions of the card slot match the cross-sectional dimensions of the card plate.

[0012] Preferably, the pressure plate is connected to one end of the spring, and the other end of the spring is connected to the side wall of the hydraulic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves pressing the pressure plate simultaneously from both the front and rear sides, causing it to slide into the inner groove. This pressure on the hydraulic rod and spring generates potential energy, which in turn moves and retracts the inner plate and clamping plate into the inner groove. The insertion box with the air outlet device is then inserted into the slot. Releasing the pressure on the pressure plate allows the spring to release its potential energy and push the pressure plate outward, causing the clamping plate to insert into the aligned slot. This completes the installation and fixation of the air outlet device. Controlling the motor to rotate the gears causes them to mesh relative to each other on the toothed plate surface. With the limiting plate embedded in the limiting groove, the slide plate slides stably back and forth in the groove, causing the air outlet device to blow air and dissipate heat at the upper end of the test push rod, thus improving the heat dissipation effect.

The base 1 is provided with a moving mechanism for adjusting the position of the heat dissipation assembly on the front and rear sides. A top frame 3 is installed on the upper end of the moving mechanism. A heat dissipation mechanism that can be disassembled and maintained separately is provided on the upper end of the top frame 3. A test push rod 5 for testing engine connecting rod vibration is provided on the upper side of the center of the base 1.

[0022] It should be noted that the moving mechanism and heat dissipation mechanism in this solution improve the heat dissipation effect of the testing equipment.

[0023] The moving mechanism includes a slide 201, in which a slide plate 202 is installed. Limiting grooves 203 are formed on the upper and lower sides of the slide 201. Limiting plates 204 are installed on the upper and lower sides of the slide plate 202. A gear 205 is installed on the rear side wall of the slide plate 202. A motor 206 is connected to the side wall of the gear 205. A side groove 207 is formed on the rear side of the slide 201. A toothed plate 208 is installed in the side groove 207.

[0024] It should be noted that: in this scheme, the motor 206 is controlled to rotate and drive the gear 205 to rotate so that they mesh relative to each other on the surface of the toothed plate 208. Under the limitation of the limiting plate 204 embedded in the limiting groove 203, the slide plate 202 slides back and forth stably in the sliding groove 201, which drives the air outlet device 410 to blow air and dissipate heat at the upper end of the test push rod 5.

[0025] The cross-sectional dimensions of the limiting groove 203 match the cross-sectional dimensions of the limiting plate 204.

[0026] It should be noted that: in this scheme, the motor 206 is controlled to rotate and drive the gear 205 to rotate so that they mesh relative to each other on the surface of the toothed plate 208. Under the limitation of the limiting plate 204 embedded in the limiting groove 203, the slide plate 202 slides back and forth stably in the sliding groove 201, which drives the air outlet device 410 to blow air and dissipate heat at the upper end of the test push rod 5.

[0027] The gear 205 meshes with the toothed plate 208.

[0028] It should be noted that: in this scheme, the motor 206 is controlled to rotate and drive the gear 205 to rotate so that they mesh relative to each other on the surface of the toothed plate 208. Under the limitation of the limiting plate 204 embedded in the limiting groove 203, the slide plate 202 slides back and forth stably in the sliding groove 201, which drives the air outlet device 410 to blow air and dissipate heat at the upper end of the test push rod 5. Example

[0029] Please see Figure 1-3 The heat dissipation mechanism includes a slot 401, a housing 402 inserted into the slot 401, an inner groove 403 formed on the side wall of the housing 402, an inner plate 404 installed in the inner groove 403, a retaining plate 405 installed at the lower end of the inner plate 404, a retaining groove 406 formed on the side wall of the slot 401, a hydraulic rod 407 installed inside the upper end of the inner groove 403, a spring 408 fitted on the outer wall of the hydraulic rod 407, a pressure plate 409 fitted on the outer wall of the spring 408, and an air outlet device 410 installed at the right end of the housing 402.

[0030] It should be noted that: In this solution, the pressure plate 409 is pressed simultaneously from both the front and rear sides, causing it to slide into the inner groove 403. This compresses the hydraulic rod 407 and spring 408, generating potential energy, which drives the inner plate 404 and the clamping plate 405 to move and retract into the inner groove 403. The insertion box 402, on which the air outlet device 410 is installed, is then inserted into the slot 401. The pressure on the pressure plate 409 is then released, and the spring 408 releases its potential energy to push the pressure plate 409 outward, causing the clamping plate 405 to be inserted outward into the aligned clamping slot 406. This completes the installation and fixation of the air outlet device 410.

[0031] The cross-sectional dimensions of the slot 406 match the cross-sectional dimensions of the card plate 405.

[0032] It should be noted that: In this solution, the pressure plate 409 is pressed simultaneously from both the front and rear sides, causing it to slide into the inner groove 403. This compresses the hydraulic rod 407 and spring 408, generating potential energy, which drives the inner plate 404 and the clamping plate 405 to move and retract into the inner groove 403. The insertion box 402, on which the air outlet device 410 is installed, is then inserted into the slot 401. The pressure on the pressure plate 409 is then released, and the spring 408 releases its potential energy to push the pressure plate 409 outward, causing the clamping plate 405 to be inserted outward into the aligned clamping slot 406. This completes the installation and fixation of the air outlet device 410.

[0033] The pressure plate 409 is connected to one end of the spring 408, and the other end of the spring 408 is connected to the side wall of the hydraulic rod 407.

[0034] It should be noted that: In this solution, the pressure plate 409 is pressed simultaneously from both the front and rear sides, causing it to slide into the inner groove 403. This compresses the hydraulic rod 407 and spring 408, generating potential energy, which drives the inner plate 404 and the clamping plate 405 to move and retract into the inner groove 403. The insertion box 402, on which the air outlet device 410 is installed, is then inserted into the slot 401. The pressure on the pressure plate 409 is then released, and the spring 408 releases its potential energy to push the pressure plate 409 outward, causing the clamping plate 405 to be inserted outward into the aligned clamping slot 406. This completes the installation and fixation of the air outlet device 410.

[0035] The working process and principle of this utility model are as follows: Pressing the pressure plate 409 simultaneously from both the front and rear sides causes it to slide into the inner groove 403, compressing the hydraulic rod 407 and spring 408 to generate potential energy, which drives the inner plate 404 and the clamping plate 405 to move and retract into the inner groove 403. The insertion box 402, on which the air outlet device 410 is installed, is inserted into the slot 401. Releasing the pressure on the pressure plate 409 causes the spring 408 to release potential energy and push the pressure plate 409 outward, causing the clamping plate 405 to be inserted outward into the aligned clamping slot 406, thus completing the installation and fixation of the air outlet device 410. Controlling the motor 206 to rotate drives the gear 205 to rotate so that it meshes with the gear plate 208. With the limiting plate 204 embedded in the limiting groove 203, the sliding plate 202 slides stably back and forth in the sliding groove 201, causing the air outlet device 410 to blow air and dissipate heat at the upper end of the test push rod 5.
