[0057] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the invention.

[0058] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0059] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term “first component” does not imply the existence of a “second component”, and the term “second component” does not imply the existence of a “first component”.

[0060] To fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below; however, in addition to these detailed descriptions, the present invention may have other embodiments.

[0061] This invention provides a tilting device. The tilting device can be used to tilt the cylinder block of an internal combustion engine (e.g., a diesel engine or a gasoline engine). Please refer to... Figures 1 to 6 The flipping device includes a mounting bracket 200 and a clamping flipping component 100. The clamping flipping component 100 is mounted on the mounting bracket 200. The clamping flipping component 100 is used to clamp the cylinder body and then flip the cylinder body 180°.

[0062] Please refer to Figure 1 , Figures 3 to 5 The clamping and flipping component 100 includes a clamping assembly 110 and a flipping assembly 130.

[0063] like Figure 4As shown, the clamping assembly 110 includes a clamping bracket 125, a first clamping assembly, and a second clamping assembly. The clamping bracket 125 is connected to the flipping bracket 133 (described later) via a slewing bearing 131. The first clamping assembly and the second clamping assembly are connected to the clamping bracket 125.

[0064] Please refer to Figure 1 and Figure 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 the vertical plate 118. The cylinder shaft of the vertical cylinder 116 is along the vertical direction D1 ( Figure 1 The vertical plate 118 extends in the vertical direction (D1) 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 support plate 119 to move in the first horizontal direction D2. In the vertical direction D1, the vertical plate 118 is located above the support plate 119, and there is a vertical gap between the vertical plate 118 and the support plate 119 in the vertical direction D1.

[0065] Please continue to refer to this. Figure 3 The first clamping assembly also includes a first vertical guide rail 126. The first vertical guide rail 126 is connected to the clamping bracket 125 and extends in the vertical direction D1. The first vertical guide rail 126 can be connected to the vertical plate 118 via a slider to guide the movement of the vertical plate 118.

[0066] The first clamping assembly also includes a first nitrogen spring 123. The first nitrogen spring 123 is connected to the vertical plate 118. In this way, when the vertical plate 118 abuts against the cylinder body, the first nitrogen spring 123 also abuts against the top of the cylinder body, thereby buffering the movement of the cylinder body in the vertical direction D1.

[0067] like Figure 3 As shown, 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 force-multiplying cylinder 111 is connected to the first horizontal plate 113. The cylinder shaft of the force-multiplying cylinder 111 extends along a first horizontal direction D2 to drive the first horizontal plate 113 to move along the first horizontal direction D2. The cylinder shaft of the horizontal positioning cylinder 112 is connected to the second horizontal plate 114. The cylinder shaft of the horizontal positioning cylinder 112 extends along the first horizontal direction D2 to drive the second horizontal plate 114 to move along the first horizontal direction D2. A first horizontal gap exists between the first horizontal plate 113 and the second horizontal plate 114 in the first horizontal direction D2.

[0068] Please continue to refer to this. Figure 3The second clamping assembly also includes a first horizontal guide rail 124. The first horizontal guide rail 124 is connected to the clamping bracket 125 and extends along a first horizontal direction D2. The first horizontal guide rail 124 can be connected to a first horizontal plate 113 via a slider to guide the movement of the first horizontal plate 113. The first horizontal guide rail 124 can also be connected to a second horizontal plate 114 via a slider to guide the movement of the second horizontal plate 114.

[0069] The second clamping assembly also includes two second nitrogen springs 127. One second nitrogen spring 127 is connected to the first horizontal plate 113. The other second nitrogen spring 127 is connected to the second horizontal plate 114. Thus, when the first horizontal plate 113 and the second horizontal plate 114 clamp the cylinder body, one second nitrogen spring 127 abuts against one end of the cylinder body along the first horizontal direction D2, and the other second nitrogen spring 127 abuts against the other end of the cylinder body along the first horizontal direction D2. Therefore, the two second nitrogen springs 127 can buffer the movement of the cylinder body in the first horizontal direction D2.

[0070] When the conveying component 190 transports the cylinder to be overturned to the predetermined position (as described below) Figure 1 When the conveying component 190 is in position, the clamping assembly 110 is moved to the cylinder body via the lifting connecting frame 141 (described later). At this time, the cylinder body is located at the first horizontal interval and at the vertical interval. The multiplier cylinder 111 and the horizontal positioning cylinder 112 can then be activated to clamp the ends of the cylinder body along the first horizontal direction D2 using the first horizontal plate 113 and the second horizontal plate 114; the clamping block cylinder 117 can be activated to move the support plate 119 to the lower side of the cylinder body to support it; and then the vertical cylinder 116 can be activated to move the vertical plate 118 downwards to abut against the top of the cylinder body. Thus, the first clamping assembly is used to clamp the two sides of the cylinder body along the vertical direction D1, and the second clamping assembly is used to clamp the two sides of the cylinder body along the first horizontal direction D2.

[0071] like Figure 4 As shown, the tilting assembly 130 includes a tilting bracket 133, a rotary motor 132, and a slewing bearing 131. The tilting bracket 133 is connected to the gantry frame 146 (described later) via a lifting connecting frame 141. The tilting bracket 133 is connected to the clamping bracket 125 via the slewing bearing 131. The rotary motor 132 is connected to the slewing bearing 131 to drive the slewing bearing 131 to rotate. Thus, the rotary motor 132 can drive the clamping bracket 125 to rotate, thereby driving the cylinder held by the first and second clamping assemblies to tilt. It should be noted that the usage of the rotary motor 132 and the slewing bearing 131 is largely the same as the existing usage of rotary motors 132 and slewing bearings 131, and will not be described in detail here.

[0072] Please return Figure 3The second clamping assembly also includes a limiting cylinder 115 and a positioning block (not shown). The positioning block and the limiting cylinder 115 are connected by a cylinder shaft. The limiting cylinder 115 is used to drive the positioning block to move. Thus, when the first horizontal plate 113 and the second horizontal plate 114 clamp the cylinder body, the limiting cylinder 115 operates to move the positioning block to a first horizontal interval between the first horizontal plate 113 and the second horizontal plate 114. At this time, the positioning block is in contact with the first horizontal plate 113 and the second horizontal plate 114. Thus, along the first horizontal direction D2, the positioning block can limit the distance between the first horizontal plate 113 and the second horizontal plate 114 clamping the cylinder body.

[0073] like Figure 3 and Figure 4 As shown, the first clamping assembly also includes a locking hydraulic cylinder 120, an unlocking hydraulic cylinder 121, and a locking wedge (not shown). A locking hole (not shown) is provided on the vertical plate 118. A locking mounting hole (not shown) is provided on the clamping bracket 125. The locking mounting hole and the locking hole are correspondingly provided. The locking wedge is movably inserted into the locking mounting hole. The wedge-shaped portion of the locking wedge extends out of the locking mounting hole and then into the locking hole. The lower surface of the wedge-shaped portion of the locking wedge is inclined upwards (along the axial direction of the locking mounting hole, the lower surface of the wedge-shaped portion of the locking wedge is inclined from bottom to top, from the locking mounting hole toward the locking hole).

[0074] The piston shafts of both the locking hydraulic cylinder 120 and the unlocking hydraulic cylinder 121 extend along the axial direction of the locking mounting hole. Along 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-shaped portion of the locking wedge, and the piston shaft of the unlocking hydraulic cylinder 121 is located at the small end of the wedge-shaped portion of the locking wedge. Thus, the piston shaft of the locking hydraulic cylinder 120 pushes the locking wedge, causing its lower surface to abut against the locking hole, thereby applying a downward force to the vertical plate 118, causing the vertical plate 118 to press against the cylinder body. This further secures the cylinder body.

[0075] If it is necessary to release the force exerted by the locking wedge on the vertical plate 118, the piston shaft of the unlocking hydraulic cylinder 121 can be used to push the locking wedge so that the lower surface of the locking wedge leaves the locking hole.

[0076] like Figure 3 As shown, pin holes can also be provided on the first horizontal plate 113, the second horizontal plate 114, and the vertical plate 118. The cylinder body is provided with cylinder body pin holes corresponding to the pin holes. The clamping assembly 110 also includes a positioning pin 122. In this way, when the vertical plate 118 clamps the cylinder body, the positioning pin 122 can be inserted into the aforementioned pin holes and cylinder body pin holes to further fix the cylinder body.

[0077] Please refer to Figure 5The clamping and tilting component 100 also includes a lifting assembly 140. The lifting assembly 140 is used to lift the tilting component 130 in the vertical direction D1. The lifting assembly 140 includes a gantry frame 146, a lifting connecting frame 141 connected to the tilting component 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 frame 146. The piston rod of the lifting hydraulic cylinder 149 is connected to the lifting connecting frame 141 to drive the lifting connecting frame 141 to move in the vertical direction D1.

[0078] The sprocket assembly includes a chain 143, a sprocket 142, and a sprocket motor (not shown). The chain 143 is arranged vertically in the direction D1. The sprocket motor's mounting base is connected to the gantry 146. The sprocket motor's motor shaft is connected to the sprocket 142. The sprocket 142 and chain 143 are engaged. The chain 143 is connected to the lifting connecting frame 141. Thus, the sprocket motor can drive the chain 143 to move via the sprocket 142, thereby driving the lifting connecting frame 141 to move vertically in the direction D1.

[0079] The motor shaft of the lead screw motor 145 is connected to the lifting lead screw 144. The lifting lead screw 144 extends in the vertical direction D1. The lifting connecting frame 141 is provided with an internal thread corresponding to the lifting lead screw 144. The lifting lead screw 144 is connected to the internal thread of the lifting connecting frame 141. In this way, the lead screw motor 145 drives the lifting lead screw 144 to rotate, thereby driving the lifting connecting frame 141 to move in the vertical direction D1. As a result, the lifting hydraulic cylinder 149, the sprocket assembly, and the lifting lead screw 144 jointly drive the lifting connecting frame 141 to move in the vertical direction D1, making the movement of the clamping assembly 110 holding the cylinder body in the vertical direction D1 more stable.

[0080] The lifting assembly 140 also includes a second vertical guide rail 160. The second vertical guide 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 connecting frame 141 via a slider to guide the movement of the lifting connecting frame 141.

[0081] Please refer to Figure 6 The clamping and tilting component 100 also includes a rail 170 and a horizontal movement assembly 180. The rail 170 is along the second horizontal direction D3 ( Figure 1The gantry 146 extends along the left and right directions (the second horizontal direction D3 is perpendicular to the first horizontal direction D2) and is fixedly connected to the mounting bracket 200. A gantry leg 147 is provided at the lower end of the gantry 146. The gantry leg 147 is provided with rollers 186. The rollers 186 can rotate on the rail 170. The horizontal movement assembly 180 includes a gear motor 181, a gear (not shown), and a rack 183. The rack 183 extends along the second horizontal direction D3 and is fixedly connected to the mounting bracket 200. The mounting base of the gear motor 181 is connected to the gantry leg 147. The motor shaft of the gear motor 181 is connected to the gear. The gear and rack 183 mesh. Thus, the gear motor 181 can drive the gear to rotate, thereby driving the gantry leg 147 to move along the second horizontal direction D3.

[0082] like Figure 6 As shown, the horizontal movement assembly 180 also includes a brake 189. The brake 189 can be an existing brake 189. The brake 189 is connected to the gantry 147 to brake the gantry 147.

[0083] like Figure 6 As shown, the horizontal movement assembly 180 also includes a second horizontal guide rail 188. The second horizontal guide rail 188 is fixedly connected to the mounting bracket 200. The second horizontal guide rail 188 extends along a second horizontal direction D3. The second horizontal guide rail 188 can be connected to the gantry bracket 147 via a slider to guide the movement of the gantry bracket 147.

[0084] like Figure 6 As shown, the horizontal movement assembly 180 also includes guide wheels (not shown). The guide wheels are connected to the gantry 147 and are located on the side of the rail 170, so that the guide wheels can guide the movement of the gantry 147.

[0085] The horizontal movement assembly 180 also includes a pin assembly and an anti-loosening assembly 185. The pin assembly includes a pin cylinder 148 and a positioning pin 184. The cylinder body of the pin cylinder 148 is connected to the gantry frame 147. The positioning pin 184 is connected to the cylinder shaft of the pin cylinder 148. The mounting bracket 200 has a pin 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 secures the gantry frame 147.

[0086] When the positioning pin 184 moves to the pin hole, part of the anti-loosening component 185 can abut against the rail 170 to fix the gantry scaffold 147.

[0087] like Figure 1As shown, the flipping device includes two clamping and flipping components 100. A second horizontal distance exists between the two clamping and flipping components 100 in the second horizontal direction D3. The two clamping and flipping components 100 are arranged opposite to each other. Therefore, the two clamping and flipping components 100 jointly flip the cylinder, resulting in a more stable flipping of the cylinder.

[0088] like Figure 1 and Figure 2 As shown, the tilting device also includes a conveying component 190. The conveying component 190 may be a conveyor belt. The conveying component 190 is mounted on the mounting frame 200. Thus, after the cylinder body is placed on the conveying component 190, the conveying component 190 can transport the cylinder body to a predetermined position.

[0089] In this embodiment, the first clamping component and the second clamping component of the flipping device can automatically clamp the cylinder body and flip the cylinder body through the flipping component 130, without the need for manual operation, which is highly efficient and has a low error rate.

[0090] The flipping device clamps the cylinder body via the clamping assembly 110, making it suitable for cylinder bodies of different heights. In the second horizontal direction D3, the distance between the two clamping and flipping assemblies 130 is adjustable, thus allowing the flipping device to flip cylinder bodies of different lengths.

[0091] The operation of the flipping device in this embodiment is as follows:

[0092] Step 1: The cylinder body is placed on the conveying component 190, and the conveying component 190 conveys the cylinder body to the predetermined position.

[0093] Step 2: The lifting component 140 operates to lower the lifting connecting frame 141, which is located at the initial connection position, to a predetermined height.

[0094] Step 3: The horizontal moving component 180 operates to move the gantry frame 146 from the initial position of the gantry to the preset position, and fix the gantry legs 147 at the preset position.

[0098] Step 7: The lifting assembly 140 operates to lower the overturned cylinder to a predetermined height;

[0099] Step 8: Clamping assembly 110 operates to place the cylinder back into conveying component 190;

[0100] Step 9: The horizontal moving component 180 operates to return the gantry frame 146 to the initial position of the gantry;

[0101] Step 10: The lifting component 140 operates to raise the lifting connecting frame 141 to the initial connection position.

[0102] Step 11: The conveying component 190 operates to move the cylinder body outside the tilting device;
