Description

Technical Field

[0001] This utility model relates to the field of vehicle production technology, and in particular to a tilting device. Background Technology

[0002] In vehicle production, the processing of the body-in-white is crucial, and the flipping of parts during the body-in-white processing is a challenge.

[0003] To flip a part, a fixture is required, and a counterweight must be placed on the fixture to ensure that the center of gravity of the part and the center of gravity of the fixture are on the same line. Only then can the flipping device be used to flip the fixture and the part.

[0004] The fixtures and parts themselves are quite heavy. Although existing flipping equipment can use motors, cylinders and other devices to achieve automatic flipping to overcome the problem of difficulty in flipping by manpower, it lacks a buffer when flipping to the required position. The impact force on the fixture during the reciprocating flipping process is extremely large, resulting in a short life of the flipping fixture. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flipping device, which aims to solve the problem that the existing flipping devices lack buffering means when flipping the fixture and parts to the required position, which easily leads to a short service life of the fixture.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A flipping device includes a driving device and a first mounting plate. The driving device includes a power mechanism, a first rotating part, a first limiting component, and a first fixing part. The power mechanism and the first fixing part are both connected to the first mounting plate. One end of the first rotating part passes through the first fixing part and is connected to the power mechanism to drive the first rotating part to rotate. The first limiting component includes a first clamping limiting block, a first limiting base, a second limiting base, a first limiting block, a second limiting block, a first buffer block, and a second buffer block. The end of the first rotating part away from the power mechanism is connected to the first clamping limiting block. The side of the plate facing the power mechanism is connected to the first limiting base and the second limiting base. The first limiting base and the second limiting base are arranged opposite to each other. The side of the first limiting base facing away from the first mounting plate is connected to the first limiting block and the first buffer block. When the first clamping limiting block does not contact the first limiting block, the top surface of the first buffer block is higher than the top surface of the first limiting block. The first limiting block and the second limiting block are arranged opposite to each other. The first limiting block, the second limiting block and the first clamping limiting block are all used to limit the rotation angle of the first rotating part. The first buffer block and the second buffer block are arranged opposite to each other.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the first clamping limit block, the first limiting block and the second limiting block, when the power mechanism drives the first rotating part to rotate, the first limiting block and the second limiting block restrict the rotation range of the first clamping limit block, thereby limiting the first rotating part connected to the first clamping limit block through the first limiting block, the second limiting block and the first clamping limit block. By setting the first buffer block and the second buffer block, when the first clamping limit block contacts the first limiting block or the second limiting block, it will preferentially contact the first buffer block or the second buffer block. During the process of flipping the clamp by the first rotating part, the limiting contact is buffered, which can not only ensure the accuracy of the limiting position, but also greatly reduce the impact force on the clamp and extend the service life of the clamp.

[0009] Furthermore, the first fixing part includes a bearing seat base and a bearing seat. The bearing seat base is connected to the first mounting plate, and the bearing seat is connected to the bearing seat on the side of the bearing seat base facing away from the first mounting plate. A first shaft hole is formed on the bearing seat, and the first shaft hole penetrates the bearing seat.

[0010] Furthermore, the first rotating part includes a first rotating disk, a first rotating shaft, and a gear. The first rotating disk is connected to the first clamping limit block and the first rotating shaft. One end of the first rotating shaft facing away from the first rotating disk passes through the first shaft hole and is connected to the gear.

[0011] Furthermore, the power mechanism includes a cylinder, a cylinder mounting base, a rack guide mechanism, and a rack. The cylinder mounting base and the rack guide mechanism are both connected to the first mounting plate. The side wall of the cylinder mounting base is connected to the cylinder. The rack guide mechanism is slidably connected to the rack. The output end of the cylinder is connected to one end of the rack to drive the rack to reciprocate. The rack meshes with the gear.

The driven device includes a second rotating part, a second limiting component, and a second fixing part. One side of the second mounting plate is connected to the second fixing part, and the side of the second mounting plate facing away from the second fixing part is connected to a second mounting base. The second limiting component includes a second clamping limiting block, a third limiting base, a fourth limiting base, a third limiting block, a fourth limiting block, a third buffer block, and a fourth buffer block. One side of the second mounting base is connected to a side plate, the third limiting base, and the fourth limiting base. A second shaft hole is formed on the side plate, and the second shaft hole penetrates the side plate. The second shaft hole is adapted to the second rotating part, the second rotating part is connected to the second clamping limiting block, the third limiting base is disposed opposite to the fourth limiting base, the third limiting base is connected to the third limiting block and the third buffer block, when the second clamping limiting block does not contact the third limiting block, the top surface of the third buffer block is higher than the top surface of the third limiting block, the third limiting block is disposed opposite to the fourth limiting block, the third limiting block, the fourth limiting block and the second clamping limiting block are all used to limit the rotation angle of the second rotating part, and the third buffer block is disposed opposite to the fourth buffer block.

[0013] Furthermore, the second rotating part includes a second rotating disk and a second rotating shaft. The second rotating disk is connected to the second clamping limit block and the second rotating shaft.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Please see Figures 1 to 4The flipping device in this embodiment of the present invention includes a driving device and a first mounting plate 130. The driving device includes a power mechanism, a first rotating part, a first limiting component, and a first fixing part. The power mechanism and the first fixing part are both connected to the first mounting plate 130. One end of the first rotating part passes through the first fixing part and is connected to the power mechanism so as to drive the first rotating part to rotate. The first fixing part includes a bearing seat base 160 and a bearing seat 161. The bearing seat base 160 is connected to the first mounting plate 130. The side of the bearing seat base 160 facing away from the first mounting plate 130 is connected to the bearing seat 161. A first shaft hole is formed on the bearing seat 161, and the first shaft hole penetrates the bearing seat 161. The first rotating part includes a first... The system comprises a rotating shaft disk 162, a first rotating shaft 163, and a gear 142. The first rotating shaft disk 162 is connected to the first rotating shaft 163. One end of the first rotating shaft 163 facing away from the first rotating shaft disk 162 passes through the first shaft hole and is connected to the gear 142. The power mechanism includes a cylinder 150, a cylinder mounting base 151, a rack guide mechanism 140, and a rack 141. Both the cylinder mounting base 151 and the rack guide mechanism 140 are connected to the first mounting plate 130. The side wall of the cylinder mounting base 151 is connected to the cylinder 150. The rack guide mechanism 140 is slidably connected to the rack 141. The output end of the cylinder 150 is connected to one end of the rack 141 to drive the rack 141 to reciprocate. The rack 141 meshes with the gear 142. Preferably, the teeth of the rack 141 face upwards, the gear 142 is located above the rack 141, the sidewall of the rack 141 is provided with a protruding guide auxiliary strip, and the rack guide mechanism 140 is provided with a plurality of rollers in the center. The sidewall of some of the rollers abuts against the bottom of the rack 141, supporting the rack 141 to a certain height and allowing the rack 141 to move on the rollers. The sidewall of another part of the rollers abuts against the top of the guide auxiliary strip, used to press the rack 141 and control the movement trajectory. The bearing seat base 160 can raise the bearing seat 161, that is, raise the first rotating shaft 163 and the gear 142, so that the gear 142 can mesh with the rack 141. Understandably, the output end of the cylinder 150 drives the rack 141 to reciprocate, thereby driving the gear 142 to reciprocate, which in turn drives the first rotating shaft 163 and the first rotating shaft disk 162 to reciprocate. The first rotating shaft disk 162 fixes the clamp, thereby realizing the flipping device to flip the clamp and the parts fixed on the clamp.

[0029] The first limiting component includes a first clamping limiting block 164, a first limiting base 170, a second limiting base, a first limiting block 171, a second limiting block, a first buffer block 172, and a second buffer block. The first rotating shaft disk 162 is connected to the first clamping limiting block 164. The side of the first mounting plate 130 facing the power mechanism is connected to the first limiting base 170 and the second limiting base. The first limiting base 170 and the second limiting base are arranged opposite to each other. The side of the first limiting base 170 facing away from the first mounting plate 130 is connected to the first limiting block 171 and the first buffer block 172. When the first clamping limiting block 164 is not in contact with the first limiting block 171, the top surface of the first buffer block 172 is higher than the top surface of the first limiting block 171. The first limiting block 171 and the second limiting block are arranged opposite to each other. The first limiting block 171, the second limiting block, and the first clamping limiting block 164 are all used to limit the rotation angle of the first rotating part. The first buffer block 172 and the second buffer block are arranged opposite to each other. Preferably, the first buffer block 172 is made of polyurethane, and in its natural state, the top of the first buffer block 172 is higher than the first limiting block 171. (See [link to relevant documentation]). Figure 4 When the first rotating shaft disk 162 is flipping the fixture, one end of the first fixture limiting block 164 rotates toward the first limiting block 171 and preferentially contacts the first buffer block 172. The first buffer block 172 undergoes elastic compression, and the height of its top surface decreases, thereby reducing the impact force until the first fixture limiting block 164 contacts the first limiting block 171. The first limiting block 171 causes the first fixture limiting block 164 to stop moving, thereby playing a buffering and limiting role on the first fixture limiting block 164, that is, it plays a buffering and limiting role in the flipping process. The first fixture limiting block 164 includes first contact portions 165 disposed at both ends. The size of the first contact portions 165 is adapted to the total size of the first limiting block 171 and the first buffer block 172. Understandably, the first buffer block 172 and the second buffer block can play a buffering role in both rotational directions of the first clamping limit block 164, and the first limit block 171 and the second limit block can play a limiting role in both rotational directions of the first clamping limit block 164. If only polyurethane blocks are used for buffering and limiting, the size of each compression cannot be guaranteed to be consistent, and the limiting of the first clamping limit block 164 is not accurate. By combining the limit block and the polyurethane block, the accuracy and consistency of the limiting are guaranteed, and the limiting during the flipping of the clamp is buffered, which greatly reduces the impact force and prevents the impact force from damaging the clamp.

[0030] The flipping device further includes a driven device and a second mounting plate 230. The driven device includes a second rotating part, a second limiting component, and a second fixing part 241. One side of the second mounting plate 230 is connected to the second fixing part 241, and the side of the second mounting plate 230 facing away from the second fixing part 241 is connected to a second mounting base. The second limiting component includes a second clamp limiting block 244, a third limiting base 221, a fourth limiting base, a third limiting block 251, a fourth limiting block, a third buffer block 252, and a fourth buffer block. One side of the second mounting base is connected to a side plate 240, the third limiting base 221, and the fourth limiting base. A second shaft hole is formed on the side plate 240, penetrating the side plate 240 and adapting to the second rotating part. The second rotating part includes a second rotating disk 242 and a second rotating shaft 243. The second rotating shaft disk 242 connects the second clamping limit block 244 and the second rotating shaft 243. One end of the second rotating shaft 243 facing away from the second rotating shaft disk 242 passes through the second shaft hole and is rotatably connected to the second fixing part 241. The third limiting base 221 is disposed opposite to the fourth limiting base. The third limiting base 221 is connected to the third limiting block 251 and the third buffer block 252. When the second clamping limit block 244 does not contact the third limiting block 251, the top surface of the third buffer block 252 is higher than the top surface of the third limiting block 251. The third limiting block 251 is disposed opposite to the fourth limiting block. The third limiting block 251, the fourth limiting block and the second clamping limit block 244 are all used to limit the rotation angle of the second rotating part. The third buffer block 252 is disposed opposite to the fourth buffer block. Preferably, the third buffer block 252 and the fourth buffer block are both made of polyurethane. The second fixing part 241 is a bearing fixing seat adapted to the second rotating shaft 243. The second rotating shaft disk 242 is used to fix one end of the clamp away from the first rotating shaft disk 162. When the clamp is flipped, the second rotating shaft disk 242 rotates accordingly. The second limiting component plays an auxiliary buffering and limiting role, making the flipping device more stable.

[0031] The second mounting plate 230 is connected to the inspection plate 231. The inspection plate 231 has an insertion hole that extends through it and is used to insert an inspection pin 232. Preferably, the inspection pin 232 is used to be inserted into the inspection hole on the second rotating shaft disk 242 for maintenance.

[0032] The side of the first mounting plate 130 facing away from the first fixing part is connected to a first mounting base, and a plurality of connecting rods 300 connect the first mounting base and the second mounting base. Preferably, the first mounting base includes a first support base 110 and a first support frame 120, and the second mounting base includes a second support base 210 and a second support frame 220. The third limiting base 221, the fourth limiting base, and the side plate 240 are all mounted on the second support frame 220. Please refer to [link / reference]. Figure 5 The number of connecting rods 300 between the first mounting base and the second mounting base is 2, which is used to enhance the structural strength and stability of the flipping device.
