DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-4 A main pump piston rod CNC processing production line includes a processing structure 1, which includes a machine tool 11 and a movable groove 12 opened on one side of the top of the machine tool 11, a drilling platform 14 is slidably installed inside the movable groove 12, a drilling member 15 is installed at the middle end of the drilling platform 14, a transverse cylinder 13 is installed on one side of the machine tool 11, and the telescopic end of the transverse cylinder 13 is installed on one side of the drilling platform 14, a clamping mechanism 16 is installed at the top of the machine tool 11 and on one side of the movable groove 12, a control mechanism 19 is installed at the bottom end of the clamping mechanism 16, and the control mechanism 19 is inside the body of the machine tool 11.

[0025] The clamping mechanism 16 includes a clamping platform 161 and a clamping groove 162 formed at the top of the clamping platform 161 . A clamping block 168 is disposed inside the clamping groove 162 .

[0026] The clamping block 168 includes a placement tube 1681, and a plurality of placement tubes 1681 are provided. The number of placement tubes 1681 is consistent with the number of drilling members 15. Connecting plates 1684 are installed between the placement tubes 1681. Side grooves 1682 are penetrated through the transverse middle ends of the placement tubes 1681 and the connecting plates 1684. A bottom groove 1683 is penetrated through the bottom end of the placement tube 1681. The main pump piston rod is arranged inside the placement tube 1681 to complete the placement of the main pump piston rod.

[0027] The control mechanism 19 includes a control box 191 and an inclined plate 192 slidably mounted inside the control box 191, a push rod 195 is mounted on the top of the inclined plate 192, a bent bar 196 is mounted on the top of the clamping block 168, and the number of the placement cylinder 1681, the bent bar 196, the clamping block 168 and the drilling member 15 is consistent, the size of the bent bar 196 is consistent with the size of the bottom groove 1683, and a limiting groove 1611 is provided at the bottom end of the clamping table 161, and the push rod 195 is connected to the limiting groove 1611. 611 matches, after the clamping block 168 equipped with the piston rod moves downward, the placing cylinder 1681 puts it on the outside of the bent bar 196 through the bottom groove 1683, and the top of the bent bar 196 passes through the inside of the bottom groove 1683 and contacts with the bottom end of the piston rod. As the clamping block 168 moves downward, the bent bar 196 pushes the piston rod upward, and when the bottom end of the placing cylinder 1681 contacts the bottom end of the clamping groove 162, the placing cylinder 1681 and the bent bar 196 clamp and position the piston rod.

[0028] A loading mechanism 17 and a unloading mechanism 18 are installed at the top of the machine tool 11 and on both sides of the clamping mechanism 16, respectively. Bevel grooves 163 are provided on both sides of the top of the clamping table 161. The inclination angle of the bevel groove 163 is consistent with the inclination angle of the clamping block 168. The piston rod is transported by the loading mechanism 17 and falls into the inclined bevel groove 163. The inclined bevel groove 163 will cause the piston rod to roll to the inside of the placement cylinder 1681 to complete the self-service loading of the piston rod. After the drilling is completed, the upward bent bar 196 will push the piston rod a certain distance. Since the clamping block 168 is tilted as a whole, the piston rod rolls from the top of the bent bar 196 to the inside of the bevel groove 163 on the other side of the top of the clamping table 161. Since the height of the unloading mechanism 18 is lower than the bevel groove 163, the piston rod can be moved to the top of the unloading mechanism 18 to complete the unloading of the piston rod.

[0029] A limiting plate 164 is installed at the top of the clamping table 161 and on one side of the clamping block 168, a fixing plate 165 is installed at the top of one side of the limiting plate 164 and above the clamping block 168, an external cylinder 166 is installed through the top of the fixing plate 165, and the output end of the external cylinder 166 is installed at the top of the clamping block 168. The clamping block 168 equipped with a piston rod is moved up and down by controlling the telescopic movement of the external cylinder 166 to assist in loading the piston rod.

[0030] In this embodiment, the piston rod is transported at the top of the feeding mechanism 17, one end of the placement cylinder 1681 and one side of the top of the clamping platform 161 are lower than the lowest end of the inclined groove 163, the piston rod is transported into the interior of the inclined groove 163, and the piston rod moves into the interior of the placement cylinder 1681 through the side groove 1682. When the piston rod fills the interior of the placement cylinder 1681, the external cylinder 166 is extended, and the clamping block 168 drives the connecting plate 1685 to the outside of the positioning rod 167. The surface moves downward to limit the downward movement of the clamping block 168. When the bottom end of the placement cylinder 1681 contacts the bottom end of the clamping groove 162, the bottom end of the connecting plate 1684 contacts the top end of the positioning strip 1621, and the bending strip 196 moves upward from the inside of the bottom groove 1683 to clamp the piston rod. The transverse cylinder 13 is started to extend it, and the drilling member 15 rotates at the same time to drill one end of the piston rod, thereby completing the loading, clamping, fixing and drilling of the piston rod.

[0031] Example 2: Please refer to Figure 2-4 A positioning strip 1621 is installed at the inner bottom end of the clamping groove 162, and the positioning strip 1621 is aligned with the connecting plate 1684 in the upper and lower positions. A positioning rod 167 is fixedly installed at the top of the clamping platform 161 and on both sides of the limit plate 164. Connecting plates 1685 are installed on both sides of the clamping block 168, and the two sides of the connecting plate 1685 are slidably sleeved on the outer surface of the positioning rod 167. The inclination of the top of the positioning strip 1621 is consistent with the inclination of the clamping block 168. The external cylinder 166 controls the clamping block 168 to move up and down, and the rear end of the clamping block 168 contacts one side of the limit plate 164. The connecting plate 1685 moves on the outer surface of the positioning rod 167 to limit the moving position of the clamping block 168.

[0032] A built-in cylinder 193 is installed inside the control box 191, and the movable end of the built-in cylinder 193 is installed at the bottom end of the inclined plate 192. Limit rods 194 are installed on both sides of the inside of the control box 191, and the limit rods 194 pass through the middle end of the inclined plate 192. The extension and retraction of the built-in cylinder 193 can control the inclined plate 192 to move up and down inside the control box 191, thereby controlling the extension and retraction of the push rod 195 and the bent bar 196.

[0033] The inclined plate 192 is arranged in an inclined shape, and the inclination of the inclined plate 192 is consistent with the inclination of the clamping block 168, so that when the inclined plate 192 moves up, it can contact the piston rod inside the clamping block 168.

[0034] In this embodiment: after the drilling is completed, the external cylinder 166 contracts and the internal cylinder 193 extends simultaneously, keeping the bent bar 196 and the placement tube 1681 clamping the piston rod. When the bottom side of the placement tube 1681 moves to the top of the clamping platform 161, the internal cylinder 193 contracts until one end of the bent bar 196 is flush with the bottom end of the placement tube 1681. At this time, the piston rod at the top of the bent bar 196 rolls through the inside of the inclined clamping block 168, and after moving out of the inside of the clamping block 168, it moves to the top of the unloading mechanism 18 through the inclined groove 163 to complete the unloading of the piston rod.

[0035] Working principle: the piston rod is loaded through the loading mechanism 17. After the piston rod moves to the inside of the clamping block 168, the clamping block 168 moves down, and the bent bar 196 pushes the piston rod from the inside of the bottom groove 1683 to clamp the piston rod, and pushes the drilling platform 14 to drive the rotating drilling member 15 to drill one end of the piston rod. After the drilling is completed, the external cylinder 166 contracts and the internal cylinder 193 extends at the same time. After the piston rod is clamped and moved, the lowest end of the clamping block 168 moves to the top of the clamping platform 161, and the internal cylinder 193 contracts a certain distance, so that the piston rod can be moved out from the inside of the inclined clamping block 168, and the piston rod moves down from the inside of the inclined groove 163 to the top of the unloading mechanism 18 to complete the unloading of the piston rod.

[0036] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
