[0051] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0052] See also Figures 1 to 6 , Specific embodiment 1, this embodiment 1 provides a measuring device for detecting the roughness of an injector seat, the measuring device includes a detection mechanism for detecting the roughness of an inner wall of an injector seat 1, a feeding mechanism for feeding the injector seat 1, a first auxiliary mechanism for clamping the injector seat 1 from the feeding mechanism to the second auxiliary mechanism, a second auxiliary mechanism for clamping and driving the injector seat 1 to rotate, a unloading mechanism for receiving the injector seat 1 after detection, and a control mechanism for controlling the operation of the feeding mechanism, the first auxiliary mechanism, the second auxiliary mechanism, the detection mechanism and the unloading mechanism. The second auxiliary mechanism and the detection mechanism have corresponding positions, for example, corresponding heights and positions, that is, when the second auxiliary mechanism clamps and drives the injector seat 1 to rotate, the detection mechanism can detect the roughness of the inner wall of the injector seat 1.

[0053] The feeding mechanism includes a pre-installed material 2 and a feeding platform. The pre-installed material 2 is arranged at an angle. A pre-installed material trough 2-1 is arranged in the pre-installed material 2. The opening of the lower end of the pre-installed material trough 2-1 corresponds to the feeding trough 8-1 of the feeding platform. The fifth cylinder 8 drives the feeding trough 8-1 to move up and down. Several injector seats 1 in the pre-installed material trough 2-1 automatically fall under the action of gravity, and fall into the feeding trough 8-1 in turn in the pre-installed material trough 2-1. The feeding trough 8-1 is driven by the fifth cylinder 8 to move upward to cooperate with the first clamp 7-1 to take the material. After taking the material, the empty feeding trough 8-1 is driven by the fifth cylinder 8 to fall back to the initial position (i.e. aligned with the opening of the lower end of the pre-installed material trough 2-1), so that the next injector seat 1 can fall into the feeding trough 8-1, and the cycle is repeated in turn.

[0054] A partition baffle 9-1 is also provided between the opening at the lower end of the pre-installed material trough 2-1 and the loading trough 8-1. The sixth cylinder 9 drives the partition baffle 9-1 to move up and down. When the sixth cylinder 9 drives the partition baffle 9-1 to move down, the opening at the lower end of the pre-installed material trough 2-1 is connected with the loading trough 8-1, so that the injector seat 1 can fall from the pre-installed material trough 2-1 into the loading trough 8-1. Then the fifth cylinder 8 drives the loading trough 8-1 to move up, and the sixth cylinder 9 drives the partition baffle 9-1 to move up. The partition baffle 9-1 blocks the opening at the lower end of the pre-installed material trough 2-1 to prevent the injector seat 1 from accidentally falling out of the pre-installed material trough 2-1, ensuring that each injector seat 1 can fall into the loading trough 8-1 in turn, and completing the subsequent detection of the roughness of the inner wall of the injector seat 1.

[0055] A limiting baffle 2-2 is provided on the top of the pre-installed material trough 2-1 to limit the position of the injector seat 1 during the movement from the top of the pre-installed material trough 2-1.

[0056] The first auxiliary mechanism includes a third cylinder 6, a first cylinder 7 and a first clamp 7-1. The third cylinder 6 is located above the feeding trough 8-1. The third cylinder 6 drives the first cylinder 7 to move up and down. The first cylinder 7 controls the first clamp 7-1 to clamp the injector seat 1 in the feeding trough 8-1. The third cylinder 6 controls the first cylinder 7 to move up and down, adjusts the height of the first cylinder 7, and the first cylinder 7 controls the first clamp 7-1 to clamp and release the injector seat 1 in the vertical direction.

[0057] The second auxiliary mechanism includes a rotating motor 3 and a second cylinder 5. A second clamp 5-1 is provided at the front end of the second cylinder 5. The second cylinder 5 controls the second clamp 5-1 to clamp or release the injector seat 1, that is, the second clamp 5-1 clamps and releases the injector seat 1 in the horizontal direction. The rotating motor 3 is connected to the driving wheel 3-1, and the rear end of the second cylinder 5 is connected to the driven wheel 3-3. A synchronous belt 3-2 is connected between the driving wheel 3-1 and the driven wheel 3-3; the rotating motor 3 indirectly drives the second cylinder 5 to rotate through the driving wheel 3-1, the synchronous belt 3-2 and the driven wheel 3-3, so as to realize the rotation of the injector seat 1 clamped by the second clamp 5-1. The rotating injector seat 1 cooperates with the detection mechanism (that is, the roughness detector and the probe 12-1) to complete the detection of the roughness of the inner wall of the injector seat 1.

[0058] The detection mechanism includes a roughness tester 12, and the roughness tester 12 drives the probe 12-1 to move forward and backward. Here, the front and back are based on the roughness tester 12, the direction toward the injector seat 1 clamped by the second clamping jaw 5-1 is the front, and the direction away from the injector seat 1 clamped by the second clamping jaw 5-1 is the back. The probe 12-1 and the second clamping jaw 5-1 cooperate to complete the roughness detection of the inner wall of the injector seat 1. The roughness tester 12 can also move up and down according to actual needs to adjust the height of the probe 12-1 so that the probe 12-1 can be more accurately attached to the inner wall of the injector seat 1.

[0059] The second auxiliary mechanism and the detection mechanism are respectively located on both sides of the feeding trough 8-1, so that the second clamping jaw 5-1 can clamp one side of the injector seat 1, and the probe 12-1 can extend into the other side (such as the opening side) of the injector seat 1 for roughness detection.

[0060] The second auxiliary mechanism also includes a fourth cylinder 4, a fourth slide rail 4-2, and a fourth connecting plate 4-1. The rotating motor 3 and the second cylinder 5 are respectively connected to the fourth connecting plate 4-1. The fourth connecting plate 4-1 moves forward and backward along the fourth slide rail 4-2 driven by the fourth cylinder 4. The front and back here are based on the fourth connecting plate 4-1. The direction toward the injector seat 1 clamped by the second clamp 5-1 is the front, and the direction away from the injector seat 1 clamped by the second clamp 5-1 is the back.

[0061] The material unloading mechanism includes a seventh cylinder 10, a seventh slide rail 10-1 and a receiving tray 11. The seventh cylinder 10 drives the receiving tray 11 to move on the seventh slide rail 10-1. For example, one end of the receiving tray 11 moves in the space between the feeding trough 8-1 and the first clamping jaw 7-1. For example, the receiving tray 11 is inclined, and the higher end 11-1 of the receiving tray moves in the space between the feeding trough 8-1 and the first clamping jaw 7-1. When the injector seat 1 completes the inner wall roughness detection, the seventh cylinder 10 drives the receiving tray 11 to move on the seventh slide rail 10-1, so that the higher end 11-1 of the receiving tray extends into the space between the feeding trough 8-1 and the first clamp 7-1 until the higher end 11-1 of the receiving tray is located directly below the first clamp 7-1, so as to receive the injector seat 1 released by the first clamp 7-1. The injector seat 1 slides along the inclined receiving tray 11 to the lower end 11-2 of the receiving tray, so as to facilitate subsequent unloading. After receiving the receiving tray 11 of the corresponding injector seat 1, the seventh cylinder 10 drives the receiving tray 11 to move on the seventh slide rail 10-1 synchronously, so that the higher end 11-1 of the receiving tray is away from the space between the feeding trough 8-1 and the first clamp 7-1, so as to avoid affecting the feeding trough 8-1 and the next injector seat 1 from rising, and to avoid interference.

[0062] A seventh support plate 10-2 for supporting the receiving tray 11 is also provided on the top of the seventh cylinder 10. There can be several seventh support plates 10-2, which are arranged in sequence to form the same inclination angle as the receiving tray 11. When the higher end 11-1 of the receiving tray extends into the space between the loading trough 8-1 and the first clamp 7-1, several seventh support plates 10-2 are against the receiving tray 11 to provide additional support for the receiving tray 11, thereby avoiding the inclination angle of the receiving tray 11 being affected by the impact of the falling injector seat 1 on the receiving tray 11.

[0063] The pre-installed material 2 is parallel to the receiving tray 11 to avoid interference between the pre-installed material 2 and the receiving tray 11 during use. The pre-installed material 2 and the receiving tray 11 are located on both sides of the loading trough 8-1. At this time, the pre-installed material 2, the receiving tray 11, the second auxiliary mechanism and the detection mechanism are located around the loading trough 8-1, corresponding to each other.

[0064] The control mechanism includes PLC (using Siemens PLC, model S7-200224XPCN) 214-2AD23-OXBB) and terminal computer display 15, PLC controls the first cylinder 7 (using SMC cylinder, model MHZA2-6D-8-0), the second cylinder 5 (using SMC cylinder, model MHS4-16D-13-0), the third cylinder 6 (using SMC cylinder, model MXF12-30-0-0), the fourth cylinder 4 (using SMC cylinder, model MXF16-50-0-0), the fifth cylinder 8 (using Qilike cylinder, model TD6×20-0), the sixth cylinder 9 (using Qilike cylinder, model TD6×10-0), the seventh cylinder 10 (using SMC cylinder, model MXF12-50-0-0) and the roughness tester 12 (using Taylor's roughness tester, model FTS iSERIES1MM M112-4580-01), the terminal computer display 15 displays the detection status of the inner wall roughness of the injector seat 1.

[0065] The measuring device is located on the working platform 14, and the terminal computer display 15 and the roughness tester 12 are located on the working platform 14; a loading and unloading platform 13 is also provided on the working platform 14, and a loading and unloading positioning plate 13-1 is provided on the top of the loading and unloading platform 13, and a through hole is provided under the loading and unloading positioning plate 13-1 corresponding to the third cylinder 6, and a mounting groove is provided under the loading and unloading platform 13 corresponding to the third cylinder 6, the fifth cylinder 8 passes through the through hole and is located in the mounting groove and is connected to the loading and unloading platform 13 through the fifth connecting block 8-2, the sixth cylinder 9 passes through the through hole and is located in the mounting groove and is connected to the loading and unloading platform 13 through the sixth connecting block 9-2, the fourth slide rail 4-2 and the fourth cylinder 4 are fixed on the loading and unloading positioning plate 13-1, the seventh slide rail 10-1 and the seventh cylinder 10 are fixed on the loading and unloading positioning plate 13-1; the third cylinder 6 is fixed on the loading and unloading positioning plate 13-1 through the third connecting bracket 6-1; the pre-installed material 2 is fixed on the loading and unloading positioning plate 13-1 through the connecting plate.

[0066] The specific operation steps are as follows: in the first step, a plurality of injector seats 1 fall from the pre-installed material trough 2-1 of the pre-installed material 2. When the first injector seat 1 falls to the partition baffle 9-1, the sixth cylinder 9 drives the partition baffle 9-1 to move downward, so that the first injector seat 1 moves forward and falls into the loading trough 8-1 (at this time, the loading trough 8-1 is in the initial position). Then the sixth cylinder 9 drives the partition baffle 9-1 to move upward to block the second injector seat 1. At the same time, the fifth cylinder 8 drives the loading trough 8-1 to move upward. The third cylinder 6 controls the first cylinder 7 to move downward. The first cylinder 7 controls the first clamp 7-1 to clamp the first injector seat 1 from the loading trough 8-1. Then the third cylinder 6 controls the first cylinder 7 to move upward until the height is aligned with the second cylinder 5. The fifth cylinder 8 drives the loading trough 8-1 to move downward until it returns to the initial position. Repeat the above operation, and the second injector seat 1 enters the loading trough 8-1.

[0067] In the second step, the fourth cylinder 4 drives the fourth connecting plate 4-1 to move along the fourth slide rail 4-2 toward the first injector seat 1 clamped by the first clamp 7-1, until the second clamp 5-1 of the second cylinder 5 is aligned with one end of the injector seat 1, and the second clamp 5-1 clamps one end of the first injector seat 1, and at the same time, the roughness tester 12 drives the probe 12-1 to move toward the first injector seat 1 clamped by the first clamp 7-1, and the probe 12-1 is embedded in the first injector seat 1 and close to the inner wall of the first injector seat 1, and then the first clamp 7-1 releases the injector seat 1, and at the same time, the third cylinder 6 drives the first cylinder 7 and the first clamp 7-1 to move upward to avoid affecting the subsequent rotation of the injector seat 1;

[0068] In the third step, the rotating motor 3 drives the third cylinder 6 to rotate, and the second clamping jaw 5-1 clamps the first injector seat 1 and rotates synchronously. After the first injector seat 1 rotates one circle, the probe 12-1 completes the detection of the roughness of the inner wall of the first injector seat 1, and the rotating motor 3 stops rotating.

[0069] In the fourth step, the third cylinder 6 drives the first cylinder 7 and the first clamp 7-1 to move downward, and the first clamp 7-1 clamps the first injector seat 1, and then the second clamp 5-1 releases one end of the first injector seat 1, and the fourth cylinder 4 drives the fourth connecting plate 4-1 to move along the fourth slide rail 4-2 away from the first injector seat 1 clamped by the first clamp 7-1, and the roughness tester 12 drives the probe 12-1 to move away from the first injector seat 1 clamped by the first clamp 7-1, so that the probe 12-1 moves out of the first injector seat 1;

[0071] The fourth step and the fifth step can be performed simultaneously to improve the operating efficiency of the entire device.
