Description

Technical Field

[0001] The present application relates to the technical field of precision casting shell making transfer equipment, and in particular to a transfer vehicle positioning device for precision casting shell making. Background Art

[0002] In the precision casting process, the transfer cart can transport multiple wax molds at one time, while the positioning of traditional transfer carts relies on manual operation or relatively simple mechanical devices, which often leads to inaccurate positioning, affecting the consistency and reliability of subsequent shell making and casting processes.

[0003] In the past, the positioning of the transfer vehicle lacked an automatic deviation correction device, resulting in slight deviations in the position of the transfer vehicle. These deviations may be magnified in precision casting and affect the quality of the final product. Utility Model Content

[0004] In view of this, the main purpose of the present application is to provide a transfer vehicle positioning device for precision casting shell making, which is helpful to solve the problem of inaccurate positioning of the transfer vehicle.

[0005] The present application provides a transfer vehicle positioning device for precision casting shell making, comprising two positioning mechanisms, the two positioning mechanisms are mirror-set on the ground at a certain distance, and the positioning cones in the two positioning mechanisms are diagonally arranged, wherein each positioning mechanism comprises:

[0006] A first bottom plate, which is fixed on the ground, first guide rails are arranged in parallel on both sides of the first bottom plate, a first fixing bracket is arranged on the first bottom plate, and a first cylinder is arranged on the first fixing bracket;

[0007] A second bottom plate, the bottom end of which is slidably arranged on the first guide rail, two second guide rails are arranged in parallel at the middle position of one side of the second bottom plate, a second cylinder is arranged between the two second guide rails and at the edge of one side of the upper end of the second bottom plate, and the side end of the second bottom plate away from the second cylinder is fixedly connected to the piston of the first cylinder, so that the first cylinder pushes the second bottom plate to slide along the first guide rail;

[0008] The Z-shaped plate includes a positioning plate, a vertical plate and a supporting plate. The two ends of the vertical plate are respectively connected to the positioning plate and the supporting plate which are parallel to each other and face oppositely. The positioning plate is provided with a positioning cone to match the positioning hole at the bottom of the transfer vehicle. The second cylinder is located at the lower end of the supporting plate, and the piston of the second cylinder pushes the Z-shaped plate up and down;

[0009] Two support platforms, the bottom ends of which are slidably arranged on the second guide rail, the lower ends of the two support platforms are connected with a connecting mechanism, and the connecting mechanism is fixedly connected to the piston of the third cylinder, so that the third cylinder pushes the two support platforms to slide along the second guide rail under the support plate and support the Z-shaped plate;

[0010] The guide rail support frame is arranged on the second bottom plate and is located outside the two second guide rails. The third guide rails are vertically arranged on both sides of the guide rail support frame. The third guide rails are slidably connected with vertical plates for the Z-shaped plate to be lifted and lowered along the third guide rails.

[0011] From the above, the positioning cone on the positioning plate is used in conjunction with the positioning hole at the bottom of the transfer vehicle to better realize the deviation correction function. Even if the transfer vehicle deviates slightly, it will not affect the positioning accuracy of the transfer vehicle, ensuring the accuracy of the placement of the wax model during the casting process, thereby improving the quality of the product. In addition, two relatively arranged positioning mechanisms, the transfer vehicle equipped with the wax model runs to the middle position of the two positioning mechanisms, the first cylinder on the two positioning mechanisms pushes out the piston, pushes the second bottom plate to move, and extends the positioning cone on the positioning plate at the lower end of the Z-type plate to below the positioning hole of the transfer vehicle, the second cylinder on the second bottom plate pushes out the piston, pushes the upper support plate of the Z-type plate to rise, and can raise the positioning cone and insert it into the positioning hole, and lift the transfer vehicle off the ground as a whole, the third cylinder on the second bottom plate pushes out the piston, pushes the two support platforms to move to the bottom of the support plate, supports the Z-type plate, the third cylinder releases the pressure and retracts the piston, the two support platforms bear the weight of the entire transfer vehicle, and avoids direct force on the cylinder.

[0012] Optionally, the connecting mechanism includes: a connecting plate, which connects the bottom plates at the lower ends of the two support platforms; an inverted L-shaped plate, the upper end of which is fixedly connected to the middle of the connecting plate, and the lower end of the inverted L-shaped plate is fixedly connected to the piston of the third cylinder.

[0013] From above, the connecting plate serves as the common connection point of the two supporting platforms, which can ensure the synchronous movement of the two supporting platforms and maintain stability in the horizontal and vertical directions; the inverted L-shaped plate provides support for fixing the position of the third cylinder.

[0014] Optionally, a second fixing bracket is provided on the second bottom plate and at one side end of the inverted L-shaped plate, and the second fixing bracket supports both ends of the third cylinder.

[0015] As described above, by directly supporting the third cylinder through the second fixed bracket, the lateral force and torque generated when the third cylinder is working can be effectively dispersed, thereby preventing the third cylinder from deflecting or shaking during operation.

[0016] Optionally, a piston positioning hole is provided on the support plate for positioning the piston of the second cylinder.

[0017] From above, the second cylinder works to push out the piston, and the piston rises to the piston positioning hole, accurately lifting the Z-shaped plate to rise, realizing automatic positioning.

[0018] Optionally, two grooves are provided on the positioning plate, and the positioning cone is installed in one of the grooves.

[0019] From the above, the positioning cone on the positioning plate of one positioning mechanism is installed in any groove at will, and the positioning cone on the positioning plate of another positioning mechanism is installed in the groove at the same position, so that when the two positioning mechanisms face each other, the positions of the two positioning cones are set diagonally, which can not only realize the deviation correction function of the transfer vehicle, but also maintain the stability of the transfer vehicle.

[0020] Optionally, a first blocking block is provided at the side edge of the first bottom plate, and a second blocking block is provided at the middle position of the bottom end of the second bottom plate, so that when the second bottom plate slides along the first guide rail, the first blocking block blocks the second blocking block to prevent the second bottom plate from sliding out of the first guide rail.

[0021] From the above, the first blocking block on the first bottom plate blocks the second guide rail on the second bottom plate, thereby effectively limiting the sliding range of the second bottom plate, which can not only prevent the second bottom plate from sliding out of the first guide rail, but also assist in positioning, that is, when the second blocking block hits the first blocking block, the second bottom plate slides into place.

[0022] Optionally, the second bottom plate, whose bottom end is slidably disposed on the first guide rail, further comprises: at least two first sliding blocks are slidably connected to each first guide rail, and the first sliding blocks are fixed at intervals at the bottom end of the second bottom plate.

[0023] As described above, by connecting the bottom end of the second bottom plate to the plurality of first sliding blocks, the supporting points of the second bottom plate on the first guide rail are dispersed, so that the weight distribution is more uniform.

[0024] Optionally, the two support platforms, whose bottom ends are slidably arranged on the second guide rails, further include: a second sliding block is slidably connected to each second guide rail, and the second sliding block is fixedly connected to the bottom plate of the lower end of the support platform.

[0025] As described above, the second sliding block serves as a sliding medium between the support platform and the second guide rail, which effectively reduces the wear of the bottom ends of the two support platforms and makes the installation of the two support platforms easier.

[0026] Optionally, the third guide rail is slidably connected to a vertical plate, and further includes: each third guide rail is slidably connected to a third sliding block, and the third sliding block is fixedly connected to the vertical plate.

[0027] As described above, the use of the third sliding block increases the contact area between the vertical plate and the third guide rail, which helps to disperse the force on the vertical plate during the lifting process, reduce local stress, and enhance the stability of the overall structure.

[0028] Optionally, a shock-absorbing mounting pad is provided at the bottom end of the second cylinder.

[0029] From above, the bottom end of the second cylinder is arranged on the second bottom plate through the shock-absorbing mounting pad, which can effectively absorb the vibration energy generated when the second cylinder is working.

[0030] In summary, the transfer vehicle positioning device for precision casting shell making provided by the present application mainly includes two relatively arranged positioning mechanisms, the two positioning mechanisms are separated by a certain distance, and the distance is at least the width of the transfer vehicle. The transfer vehicle runs to the middle position of the two positioning mechanisms, and the first cylinder on the two positioning mechanisms pushes out the piston to push the second base plate to move, and the positioning cone on the positioning plate at the lower end of the Z-type plate is extended to the bottom of the positioning hole of the transfer vehicle. The second cylinder on the second base plate pushes out the piston to push the upper support plate of the Z-type plate to rise, and the positioning cone can be inserted into the positioning hole, and the transfer vehicle is lifted off the ground as a whole. The positioning cone on the positioning plate is used in conjunction with the positioning hole at the bottom of the transfer vehicle, which can better realize the deviation correction function. Even if the transfer vehicle deviates slightly, it will not affect the positioning accuracy of the transfer vehicle, ensuring the accuracy of the placement of the wax mold during the casting process, thereby improving the quality of the product. The third cylinder on the second base plate pushes out the piston, pushing the two support platforms to move to the bottom of the support plate to support the Z-type plate. The third cylinder releases pressure and retracts the piston. The two support platforms bear the weight of the entire transfer vehicle, avoiding direct force on the cylinder.

The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] Figure 1 This is a schematic diagram of the installation structure of a transfer vehicle positioning device for precision casting shell making in this application, such as Figure 1 As shown, the present application provides a transfer vehicle positioning device for precision casting shell making, which includes two positioning mechanisms, the two positioning mechanisms are mirror-set on the ground at a certain distance, and the positioning cones 2034 in the two positioning mechanisms are diagonally arranged, wherein each positioning mechanism includes:

[0044] A first bottom plate 1 is fixed on the ground, first guide rails 101 are arranged in parallel on both sides of the first bottom plate 1, a first fixing bracket 103 is arranged on the first bottom plate 1, and a first cylinder 102 is arranged on the first fixing bracket 103;

[0045] The second bottom plate 2, whose bottom end is slidably arranged on the first guide rail 101, has two second guide rails 201 arranged in parallel at the middle position of one side of the second bottom plate 2, and a second cylinder 202 is arranged between the two second guide rails 201 and at the edge of one side of the upper end of the second bottom plate 2, and the side end of the second bottom plate 2 away from the second cylinder 202 is fixedly connected to the piston of the first cylinder 102, so that the first cylinder 102 can push the second bottom plate 2 to slide along the first guide rail 101;

[0046] The Z-shaped plate 203 includes a positioning plate 2031, a vertical plate 2032 and a supporting plate 2033. The two ends of the vertical plate 2032 are respectively connected to the positioning plate 2031 and the supporting plate 2033 which are parallel to each other and face in opposite directions. The positioning plate 2031 is provided with a positioning cone 2034 to match the positioning hole at the bottom of the transfer vehicle. The second cylinder 202 is located at the lower end of the supporting plate 2033. The piston of the second cylinder 202 pushes the Z-shaped plate 203 to rise and fall.

[0047] Two support platforms 206, whose bottom ends are slidably arranged on the second guide rail 201, and the lower ends of the two support platforms 206 are connected with a connecting mechanism, which is fixedly connected to the piston of the third cylinder 204, so that the third cylinder 204 can push the two support platforms 206 to slide along the second guide rail 201 under the support plate 2033 and support the Z-shaped plate 203;

[0048] The guide rail support frame 207 is arranged on the second base plate 2 and is located outside the two second guide rails 201. Third guide rails 208 are vertically arranged on both sides of the guide rail support frame 207. Vertical plates 2032 are slidably connected to the third guide rails 208 for the Z-shaped plate 203 to be lifted and lowered along the third guide rails 208.

[0049] Specifically, the positioning cone 2034 on the positioning plate 2031 is used in conjunction with the positioning hole at the bottom of the transfer vehicle to better realize the correction function. Even if the transfer vehicle deviates slightly, it will not affect the positioning accuracy of the transfer vehicle, thereby ensuring the accuracy of the placement of the wax model during the casting process, thereby improving the quality of the product. In addition, there are two relatively arranged positioning mechanisms, and the transfer vehicle equipped with the wax model runs to the middle position of the two positioning mechanisms. The first cylinder 102 on the two positioning mechanisms pushes out the piston, pushes the second base plate 2 to move, and extends the positioning cone 2034 on the positioning plate 2031 at the lower end of the Z-shaped plate 203 to below the positioning hole of the transfer vehicle. The second cylinder 202 on the second base plate 2 pushes out the piston, and pushes the support plate 2033 at the upper end of the Z-shaped plate 203 to rise, so that the positioning cone 2034 can be raised and inserted into the positioning hole, and the transfer vehicle as a whole is lifted off the ground. The third cylinder 204 on the second base plate 2 pushes out the piston, and pushes the two support platforms 206 to move to below the support plate 2033 to support the Z-shaped plate 203. The third cylinder 204 releases pressure and retracts the piston. The two support platforms 206 bear the weight of the entire transfer vehicle, avoiding direct force on the cylinder.

[0050] like Figure 1 In the specific embodiment shown, two positioning mechanisms are relatively arranged and fixed on the ground and are spaced a certain distance apart (see Figure 1 The rectangle between the two positioning mechanisms in the transfer vehicle is at least a distance including the width of the transfer vehicle, and the positioning cones 2034 are arranged diagonally in the two opposite positioning mechanisms. When the transfer vehicle is transferred to the middle rectangular position, the first cylinder 102 in the two positioning mechanisms pushes the second base plate 2 to slide forward, and pushes the positioning cone 2034 on the Z-shaped plate 203 to below the positioning hole at the bottom of the transfer vehicle, and then the second cylinder 202 is pushed out, driving the Z-shaped plate 203 to rise along the third guide rail 208, inserting the positioning cone 2034 into the positioning hole, and lifting the transfer vehicle off the ground, and then the third cylinder 204 is pushed out, pushing the support platform 206 to below the support plate 2033 of the Z-shaped plate 203, lifting the Z-shaped plate 203, and releasing the second cylinder 202, thus completing the positioning and lifting operation of the transfer vehicle.

[0051] Optionally, a second fixing bracket 212 is provided on the second bottom plate 2 and at one side end of the inverted L-shaped plate 211 , and the second fixing bracket 212 supports two ends of the third cylinder 204 .

[0052] Specifically, by directly supporting the third cylinder 204 through the second fixing bracket 212 , the lateral force and torsional force generated when the third cylinder 204 is working can be effectively dispersed, thereby preventing the third cylinder 204 from deflecting or shaking during the working process.

[0053] Optionally, the connection mechanism includes: a connection plate 210, which connects the bottom plates of the lower ends of the two support platforms 206; an inverted L-shaped plate 211, whose upper end is fixedly connected to the middle of the connection plate 210, and the lower end of the inverted L-shaped plate 211 is fixedly connected to the piston of the third cylinder 204.

[0054] Specifically, the connecting plate 210 serves as a common connection point of the two support platforms 206 , which can ensure that the two support platforms 206 move synchronously and maintain stability in the horizontal and vertical directions; the inverted L-shaped plate 211 provides support for fixing the position of the third cylinder 204 .

[0055] Optionally, a piston positioning hole is provided on the support plate 2033 for positioning the piston of the second cylinder 202 .

[0056] Specifically, the second cylinder 202 works to push out the piston, and the piston rises to the piston positioning hole, accurately lifting the Z-shaped plate 203 to achieve automatic positioning.

[0057] Figure 2 The structural diagram of the positioning mechanism is specifically shown. Figure 2 In the embodiment shown, both ends of the connecting plate 210 are fixed to the bottom plates at the lower ends of the two support platforms 206 through a small end plate, and an inverted L-shaped plate 211 is fixed in the middle of the connecting plate 210. The lower end of the inverted L-shaped plate 211 is connected to the piston of the third cylinder 204. The third cylinder 204 is fixed at both ends through the second fixed bracket 212. When the third cylinder 204 is working, its piston is pushed out, driving the two support platforms 206 to slide forward along the second guide rail 201, and slide to the bottom of the support plate 2033 of the Z-shaped plate 203 and play a supporting role. In addition, when the second cylinder 202 is working, its piston is pushed out and extends into the piston positioning hole on the support plate 2033, accurately driving the Z-shaped plate 203 to rise.

[0058] Optionally, the second bottom plate 2 , whose bottom end is slidably disposed on the first guide rail 101 , further comprises: at least two first sliding blocks 104 are slidably connected to each first guide rail 101 , and the first sliding blocks 104 are fixed at intervals at the bottom end of the second bottom plate 2 .

[0059] Specifically, by connecting the bottom end of the second bottom plate 2 to the plurality of first sliding blocks 104 , the supporting points of the second bottom plate 2 on the first guide rail 101 are dispersed, so that the weight distribution is more uniform.

[0060] Optionally, the two support platforms 206 , whose bottom ends are slidably disposed on the second guide rails 201 , further include: each second guide rail 201 is slidably connected to a second sliding block 205 , and the second sliding block 205 is fixedly connected to a bottom plate at the lower end of the support platform 206 .

[0061] Specifically, the second sliding block 205 serves as a sliding medium between the support platform 206 and the second guide rail 201 , effectively reducing the wear of the bottom ends of the two support platforms 206 , making the installation of the two support platforms 206 easier.

[0062] Optionally, the third guide rail 208 is slidably connected to a vertical plate 2032 , and further includes: each third guide rail 208 is slidably connected to a third sliding block 209 , and the third sliding block 209 is fixedly connected to the vertical plate 2032 .

[0063] Specifically, the use of the third sliding block 209 increases the contact area between the vertical plate 2032 and the third guide rail 208, which helps to disperse the force on the vertical plate 2032 during the lifting process, reduce local stress, and enhance the stability of the overall structure.

[0064] Optionally, a first blocking block 105 is provided at the side edge of the first bottom plate 1, and a second blocking block 213 is provided at the middle position of the bottom end of the second bottom plate 2, so that when the second bottom plate 2 slides along the first guide rail 101, the first blocking block 105 blocks the second blocking block 213 to prevent the second bottom plate 2 from sliding out of the first guide rail 101.

[0065] Specifically, the first blocking block 105 on the first bottom plate 1 blocks the second guide rail on the second bottom plate 2, thereby effectively limiting the sliding range of the second bottom plate 2, which can not only prevent the second bottom plate 2 from sliding out of the first guide rail 101, but also assist in positioning, that is, when the second blocking block 213 hits the first blocking block 105, the second bottom plate 2 slides into place.

[0066] Optionally, two grooves are provided on the positioning plate 2031, and the positioning cone 2034 is installed in one of the grooves.

[0067] Specifically, the positioning cone 2034 on the positioning plate 2031 of one positioning mechanism is arbitrarily installed in any groove, and the positioning cone 2034 on the positioning plate 2031 of the other positioning mechanism is installed in a groove at the same position, so that when the two positioning mechanisms are face to face, the positions of the two positioning cones 2034 are set diagonally, which can not only realize the deviation correction function of the transfer vehicle, but also maintain the stability of the transfer vehicle.

[0068] Optionally, a shock-absorbing mounting pad 214 is disposed at the bottom end of the second cylinder 202 .

[0069] Specifically, the bottom end of the second cylinder 202 is arranged on the second bottom plate 2 through a shock-absorbing mounting pad 214, which can effectively absorb the vibration energy generated when the second cylinder 202 is working.

[0070] Figure 3 The structural diagram of the positioning mechanism is specifically shown. Figure 3 In the specific embodiment shown, the first blocking block 105 and the second blocking block 213 are both L-shaped, and when the two are in motion and collide, the positioning cone 2034 on the Z-shaped plate 203 is already located below the positioning hole of the transfer vehicle. The arrangement of the first sliding block 104, the second sliding block 205 and the third sliding block 209 reduces the wear of the device and increases the sliding flexibility.

[0071] In addition, Figure 3 On the third guide rail 208 shown, a blocking block may be provided at the top of the third guide rail 208 to block the Z-shaped plate 203 and prevent the Z-shaped plate 203 from sliding out of the third guide rail 208.

[0072] To summarize, the transfer vehicle positioning device for precision casting shell making provided in the present application mainly includes two relatively arranged positioning mechanisms, the two positioning mechanisms are separated by a certain distance, and the distance is at least the width of the transfer vehicle. When the transfer vehicle runs to the middle position of the two positioning mechanisms, the first cylinder 102 on the two positioning mechanisms pushes out the piston, pushes the second base plate 2 to move, and extends the positioning cone 2034 on the positioning plate 2031 at the lower end of the Z-type plate 203 to below the positioning hole of the transfer vehicle. The second cylinder 202 on the second base plate 2 pushes out the piston, pushes the support plate 2033 at the upper end of the Z-type plate 203 to rise, and can lift the positioning cone 2034 to rise and insert it into the positioning hole, and lift the transfer vehicle as a whole off the ground. The positioning cone 2034 on the positioning plate 2031 is used in conjunction with the positioning hole at the bottom of the transfer vehicle, which can better realize the correction function. Even if the transfer vehicle deviates slightly, it will not affect the positioning accuracy of the transfer vehicle, thereby ensuring the accuracy of the placement of the wax mold during the casting process, thereby improving the quality of the product. The third cylinder 204 on the second bottom plate 2 pushes out the piston, pushing the two support platforms 206 to move to the bottom of the support plate 2033 to support the Z-shaped plate 203. The third cylinder 204 releases pressure to retract the piston, and the two support platforms 206 bear the weight of the entire transfer vehicle, avoiding direct force on the cylinder.
