The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

The utility model provides a turnover device. The turnover device may be used to turn over a cylinder of an internal combustion engine (e.g., a diesel engine or a gasoline engine). Referring to fig. 1 to 6, the turnover device includes a mounting frame 200 and a holding turnover member 100. The grip flipping member 100 is provided on the mounting frame 200. The grip turning part 100 serves to grip the cylinder and then turn the cylinder 180 °.

Referring to fig. 1, 3 to 5, the clamping and flipping part 100 includes a clamping assembly 110 and a flipping assembly 130.

As shown in fig. 4, clamping assembly 110 includes a clamping bracket 125, a first clamping assembly, and a second clamping assembly. The clamp bracket 125 is connected to a later inversion bracket 133 through a later slewing bearing 131. The first and second clamp assemblies are connected to clamp bracket 125.

Referring to fig. 1 and 3, the first clamping assembly includes a vertical plate 118, a vertical cylinder 116, a support plate 119, and a clamping block cylinder 117. The cylinder shaft of the vertical cylinder 116 is connected to a vertical plate 118. The cylinder shaft of the vertical cylinder 116 extends in the vertical direction D1 (up-down direction in fig. 1) to drive the vertical plate 118 to move in the vertical direction D1. The cylinder shaft of the clamping block cylinder 117 is connected to the support plate 119. The cylinder shaft of the clamping block cylinder 117 extends in the first horizontal direction D2 to drive the movement of the support plate 119 in the first horizontal direction D2. In the vertical direction D1, the vertical plate 118 is located above the support plate 119, and the vertical plate 118 and the support plate 119 are vertically spaced in the vertical direction D1.

With continued reference to fig. 3, the first clamping assembly further includes a first vertical rail 126. The first vertical rail 126 is connected to the clamp bracket 125 and extends in the vertical direction D1. The first vertical rail 126 may be connected to the vertical plate 118 by a slider to guide the movement of the vertical plate 118.

The first clamping assembly further includes a first nitrogen spring 123. A first nitrogen spring 123 is connected to the vertical plate 118. Thus, when the vertical plate 118 abuts the cylinder, the first nitrogen spring 123 also abuts the top end of the cylinder, and the movement of the cylinder can be damped in the vertical direction D1.

As shown in fig. 3, the second clamping assembly includes a first horizontal plate 113, a force multiplying cylinder 111, a second horizontal plate 114, and a horizontal positioning cylinder 112. The cylinder shaft of the double force cylinder 111 is connected to the first horizontal plate 113. The cylinder axis of the force multiplying cylinder 111 extends in the first horizontal direction D2 to drive the first horizontal plate 113 to move in the first horizontal direction D2. The cylinder shaft of the horizontal positioning cylinder 112 is connected to a second horizontal plate 114. The cylinder axis of the horizontal positioning cylinder 112 extends in the first horizontal direction D2 to drive the second horizontal plate 114 to move in the first horizontal direction D2. The first horizontal plate 113 and the second horizontal plate 114 have a first horizontal interval in the first horizontal direction D2.

With continued reference to fig. 3, the second clamping assembly further includes a first horizontal rail 124. The first horizontal rail 124 is connected to the clamping bracket 125 and extends in the first horizontal direction D2. The first horizontal guide rail 124 may be connected to the first horizontal plate 113 by a slider to guide the movement of the first horizontal plate 113. The first horizontal rail 124 may also be coupled to the second horizontal plate 114 via a slider to guide the movement of the second horizontal plate 114.

The second clamping assembly further includes two second nitrogen springs 127. A second gas spring 127 is connected to the first horizontal plate 113. Another second gas spring 127 is connected to the second horizontal plate 114. Thus, when the first and second

horizontal plates

113 and 114 clamp the cylinder, one second gas spring 127 abuts against one end of the cylinder in the first horizontal direction D2, and the other second gas spring 127 abuts against the other end of the cylinder in the first horizontal direction D2. Thereby, the two second gas springs 127 can buffer the movement of the cylinder in the first horizontal direction D2.

When the following transport means 190 transports the cylinder to be turned to a predetermined position (in fig. 1, the position of the transport means 190), the gripping assembly 110 is moved to the cylinder by the following lifting link 141, while the cylinder is located at the first horizontal interval and at the vertical interval. At this time, the force doubling cylinder 111 and the horizontal positioning cylinder 112 may be operated such that the first horizontal plate 113 and the second horizontal plate 114 clamp the ends of the cylinder in the first horizontal direction D2; the clamping block cylinder 117 is operated to move the supporting plate 119 to the lower side of the cylinder body to support the cylinder body; the vertical cylinder 116 is then operated to move the vertical plate 118 downwardly to abut the top end of the cylinder block. Thus, the first clamping assembly is used for clamping both sides of the cylinder in the vertical direction D1, and the second clamping assembly is used for clamping both sides of the cylinder in the first horizontal direction D2.

As shown in fig. 4, the flipping unit 130 includes a flipping bracket 133, a swing motor 132, and a swing bearing 131. The turning bracket 133 is connected to a later gantry 146 through a later lifting link 141. The turning bracket 133 is connected to the clamping bracket 125 through a pivoting support 131. A rotary motor 132 is connected to the rotary support 131 to drive the rotary support 131 to rotate. Thus, the clamping bracket 125 can be driven to rotate by the rotary motor 132, so as to drive the cylinder clamped by the first clamping assembly and the second clamping assembly to turn. It should be noted that the usage of the rotation motor 132 and the rotation support 131 is substantially the same as the usage of the conventional rotation motor 132 and the rotation support 131, and the description thereof is omitted.

Returning to fig. 3, the second clamping assembly further includes a spacing cylinder 115 and a positioning block (not shown). The positioning block is connected with the cylinder shaft of the limiting cylinder 115. The limiting air cylinder 115 is used for driving the positioning block to move. Thus, when the first and second

horizontal plates

113 and 114 clamp the cylinder body, the stopper cylinder 115 operates to move the positioning block to the first horizontal interval between the first and second

horizontal plates

113 and 114. The positioning is now fast with the first horizontal plate 113 and with the second horizontal plate 114. Thus, in the first horizontal direction D2, the positioning block may define the distance between the first horizontal plate 113 and the second horizontal plate 114 of the clamping cylinder.

As shown in fig. 3 and 4, the first clamp assembly further includes a locking hydraulic cylinder 120, an unlocking hydraulic cylinder 121, and a locking wedge (not shown). Locking holes (not shown) are provided in the vertical plate 118. The clamping bracket 125 is provided with a locking mounting hole (not shown). The locking mounting hole and the locking hole are correspondingly arranged. The locking wedge is movably arranged in the locking mounting hole in a penetrating mode. The wedge-shaped part of the locking wedge extends out of the locking mounting hole and then extends into the locking hole. The lower surface of the wedge portion of the locking wedge is inclined upward (from bottom to top in the axial direction of the locking mounting hole, toward the locking hole from the locking mounting hole).

The piston shaft of the lock cylinder 120 and the piston shaft of the unlock cylinder 121 each extend in the axial direction of the lock mounting hole. In the axial direction of the locking mounting hole, the piston shaft of the locking hydraulic cylinder 120 is located at the large end of the wedge portion of the locking wedge, and the piston shaft of the unlocking hydraulic cylinder 121 is located at the small end of the wedge portion of the locking wedge. In this way, the piston shaft of locking cylinder 120 pushes the locking wedge, which may cause the lower surface of the locking wedge to abut the locking hole, thereby applying a downward force to vertical plate 118 to cause vertical plate 118 to compress the cylinder. Whereby the cylinder can be further fixed.

If it is desired to relieve the locking wedge from the vertical plate 118, the piston shaft of the unlocking hydraulic cylinder 121 may be caused to push the locking wedge so that the lower surface of the locking wedge is clear of the locking aperture.

As shown in fig. 3, the first horizontal plate 113, the second horizontal plate 114, and the vertical plate 118 may be further provided with a pin hole. The cylinder body is provided with a cylinder body bolt hole which corresponds to the bolt hole. The clamp assembly 110 also includes a locating pin 122. Thus, after the vertical plate 118 clamps the cylinder body, the positioning pin 122 may be inserted through the above-mentioned pin hole and the cylinder body pin hole to further fix the cylinder body.

Referring to fig. 5, the clamping and flipping unit 100 further includes a lifting assembly 140. The lifting assembly 140 is used to lift the flipping assembly 130 in the vertical direction D1. The lifting assembly 140 includes a gantry 146, a lifting link 141 connected to the flipping assembly 130, a lifting hydraulic cylinder 149, a sprocket assembly, a lifting screw 144, and a screw motor 145. The hydraulic cylinder of the lifting hydraulic cylinder 149 is connected to the gantry 146. The piston rod of the lifting hydraulic cylinder 149 is connected to the lifting link 141 to drive the lifting link 141 to move in the vertical direction D1.

The sprocket assembly includes a chain 143, a sprocket 142 and a sprocket motor (not shown). The chain 143 is arranged in the vertical direction D1. The mounting base of the sprocket motor is connected to the gantry 146. The motor shaft of the sprocket motor is connected to the sprocket 142. The sprocket 142 meshes with the chain 143. The chain 143 is connected to the lifting link 141. Thus, the chain wheel motor can drive the chain 143 to move through the chain wheel 142, and further drive the lifting link 141 to move in the vertical direction D1.

The motor shaft of the screw motor 145 is connected to the lift screw 144. The lift screw 144 extends in the vertical direction D1. The lifting link 141 is provided with an internal thread corresponding to the lifting screw 144. The lifting screw 144 is connected to the internal thread of the lifting link 141. Thus, the screw motor 145 drives the lifting screw 144 to rotate, and further drives the lifting link 141 to move in the vertical direction D1. Thus, the lifting hydraulic cylinder 149, the chain wheel assembly, and the lifting screw 144 jointly drive the lifting link 141 to move in the vertical direction D1, and the movement of the clamping assembly 110 of the clamping cylinder in the vertical direction D1 is smoother.

The lift assembly 140 also includes a second vertical rail 160. The second vertical rail 160 extends in the vertical direction D1 and is connected to the gantry 146. The second vertical guide rail 160 is connected to the lifting link 141 by a slider to guide the movement of the lifting link 141.

Referring to fig. 6, the gripping and turning member 100 further includes a rail 170 and a horizontal movement assembly 180. The rail 170 extends in a second horizontal direction D3 (the left-right direction in fig. 1, the second horizontal direction D3 being perpendicular to the first horizontal direction D2) and is fixedly connected to the mounting bracket 200. The lower end of the portal frame 146 is provided with a portal foot frame 147. The gantry foot stand 147 is provided with rollers 186. The rollers 186 can rotate on the rails 170. The horizontal movement assembly 180 includes a gear motor 181, a gear (not shown), and a rack gear 183. The rack gear 183 extends in the second horizontal direction D3 and is fixedly connected to the mounting bracket 200. The mount for the gear motor 181 is connected to the gantry foot stand 147. A motor shaft of the gear motor 181 is connected to the gear. The gear is engaged with the rack 183. Thus, the gear motor 181 can drive the gear to rotate, and further drive the gantry foot 147 to move along the second horizontal direction D3.

As shown in fig. 6, the horizontal moving assembly 180 further includes a stopper 189. The brake 189 may be an existing brake 189. A brake 189 is connected to the gantry foot 147 to brake the gantry foot 147.

The horizontal movement assembly 180 further includes a latch assembly and a locking assembly 185. The latch assembly includes a latch cylinder 148 and a positioning latch 184. The cylinder of the bolt cylinder 148 is connected to a gantry foot stand 147. The positioning latch 184 is connected to the cylinder shaft of the latch cylinder 148. The mounting bracket 200 is provided with a latch hole (not shown) at the rail 170. When the positioning pin 184 moves to the pin hole, the pin cylinder 148 operates to insert the positioning pin 184 into the pin hole. This fixes the gantry foot stand 147.

When the positioning pin 184 moves to the pin hole, a portion of the anti-loosening assembly 185 may abut the rail 170 to secure the gantry foot 147.
