Description
Technical Field
[0001] The present application relates to the field of sand core preparation, and in particular to a sand core transporting mechanism. Background Art
[0002] Sand core is the material used to make cores in foundry production. It is made by a core making machine. After the core making machine is finished, the sand core in the core box needs to be taken out.
[0003] In the prior art, the sand cores in the core box are generally removed manually. However, some core making machines can produce multiple sand cores at a time. Manually removing and transporting multiple sand cores one by one is not only time-consuming and labor-intensive, but also easily causes damage to the sand cores. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the present application provides a sand core transporting mechanism with high transport efficiency.
[0005] The sand core transport mechanism provided in this application adopts the following technical solution:
[0006] A sand core transport mechanism comprises a transport seat and a plurality of grabbing assemblies arranged at the bottom of the transport seat, wherein the plurality of grabbing assemblies are arranged at intervals in pairs.
[0007] By adopting the above technical solution, multiple grabbing components can be integrated on the same transport base, and the transport base can drive multiple grabbing components to grab multiple sand cores at a time, effectively improving the transport efficiency of the sand cores; at the same time, the spacing between the two can prevent the multiple grabbing components from interfering with each other during the sand core transport process.
[0008] In a specific feasible implementation scheme, the multiple grabbing components include a first grabbing component and a second grabbing component respectively arranged on both sides of the transport seat in the width direction, and a third grabbing component arranged in the middle of the transport seat, and there is a clearance gap between the first grabbing component and the third grabbing component, and between the third grabbing component and the second grabbing component.
[0009] By adopting the above technical solution, the clearance gap can provide clearance space for the first grabbing assembly, the second grabbing assembly and the third grabbing assembly to ensure that the first grabbing assembly, the second grabbing assembly and the third grabbing assembly can stably grab the sand core.
[0010] In a specific possible implementation scheme, two first long grooves are formed on the transport seat, and the two first long grooves are respectively located in the two clearance gaps.
[0011] By adopting the above technical solution, the weight of the transport seat can be effectively reduced and the processing cost of the transport seat can be reduced; at the same time, since the first long groove is opened in the clearance, it will not affect the installation of the first grabbing assembly, the second grabbing assembly and the third grabbing assembly on the transport seat.
[0012] In a specific possible implementation scheme, the first grasping assembly includes two first grasping members spaced apart along the length direction of the transport base, each of the first grasping members includes at least one first clamping claw, and the opening and closing direction of the first clamping claw is the same as the width direction of the transport base.
[0013] In a specific possible implementation manner, each of the first grasping members includes two first clamping jaws, and the two first clamping jaws are arranged at intervals along the length direction of the transport base.
[0014] By adopting the above technical solution, the two first clamping jaws can respectively clamp the two ends of the sand core, and the two first clamping jaws cooperate with each other to effectively improve the handling stability of the sand core.
[0015] In a specific possible implementation scheme, the second grasping assembly includes two second clamping jaws arranged along the length direction of the transport base, the opening and closing direction of the two second clamping jaws is the same as the width direction of the transport base, and each of the second clamping jaws includes two oppositely arranged claw bodies, and the sides of the two claw bodies are respectively provided with extension parts.
[0016] By adopting the above technical solution, the two second clamping jaws can increase the contact area with the sand core through their extended parts, thereby preventing the sand core from shaking during the transportation process.
[0017] In a specific possible implementation scheme, the third grasping assembly includes two third clamping jaws spaced apart along the length direction of the transport base, and the opening and closing directions of the two third clamping jaws are the same as the length direction of the transport base.
[0018] By adopting the above technical solution, the two third clamping jaws can grab the sand cores outside the grabbing range of the first grabbing assembly and the second grabbing assembly, further improving the handling efficiency of the sand cores.
[0019] In a specific possible implementation scheme, the sand core transport mechanism also includes two supporting assemblies respectively arranged at both ends of the transport seat in the length direction, and each of the supporting assemblies includes a supporting frame movably arranged along the length direction of the transport seat, a driving member for driving the supporting frame to move, and a supporting block arranged at the bottom of the supporting frame.
[0020] By adopting the above technical solution, the supporting block can be supported on the lower part of one end of the sand core during the movement of the supporting frame, so as to cooperate with one of the grabbing components and carry the sand core with multiple ends.
[0021] In a specific possible implementation scheme, the transport seat is provided with a second long groove at both ends in the length direction thereof.
[0022] By adopting the above technical solution, the weight of the transport seat can be effectively reduced and the processing cost of the transport seat can be reduced.
[0023] In a specific possible implementation scheme, a connecting seat is provided on the top of the transport seat.
[0024] By adopting the above technical solution, it is convenient to connect the transport seat with the external driving mechanism to drive the movement of multiple grabbing components.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. Multiple grabbing components can be integrated on the same transport base, which can drive multiple grabbing components to grab multiple sand cores at a time, effectively improving the transport efficiency of sand cores;
[0027] 2. The two-by-two spacing setting can prevent multiple grabbing components from interfering with each other during the sand core transportation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below with reference to the accompanying drawings.
[0033] See also Figure 1-2As shown, a sand core transporting mechanism is shown, which includes a transporting seat 1, a connecting seat 9 arranged on the top of the transporting seat 1, and a plurality of grabbing components arranged at the bottom of the transporting seat 1. The connecting seat 9 is connected to an external driving mechanism, and the plurality of grabbing components are arranged in pairs.
[0034] After the core making machine completes the core making, the transport base 1 moves to the top of the core box. The multiple grabbing assemblies integrated on the transport base 1 can grab multiple sand cores 100 simultaneously or sequentially. After the grabbing is completed, the transport base 1 drives the multiple grabbing assemblies away from the core box, thereby completing the transportation of the sand cores 100. In this way, the transport base 1 can drive the multiple grabbing assemblies to grab multiple sand cores 100 at a time, eliminating the need to manually transport the sand cores 100 one by one, effectively improving the transportation efficiency of the sand cores 100. At the same time, the spacing between the two can prevent the multiple grabbing assemblies from interfering with each other during the transportation of the sand cores 100.
[0035] In this embodiment, the plurality of gripping assemblies include a first gripping assembly 2 and a second gripping assembly 3, respectively provided on both sides of the transport base 1 in the width direction, and a third gripping assembly 4 provided in the middle of the transport base 1. A clearance gap 5 is provided between the first gripping assembly 2 and the third gripping assembly 4, and between the third gripping assembly 4 and the second gripping assembly 3. The clearance gap 5 can provide clearance space for the first gripping assembly 2, the second gripping assembly 3, and the third gripping assembly 4, so as to ensure that the first gripping assembly 2, the second gripping assembly 3, and the third gripping assembly 4 can stably grip the sand core 100.
[0036] The transport base 1 also has two first elongated slots 6 extending along its length and located in the two clearance gaps 5. These slots 6 effectively reduce the weight of the transport base 1 and lower its manufacturing cost. Furthermore, because the slots 6 are located in the clearance gaps 5, they do not interfere with the installation of the first, second, and third gripping assemblies 2, 3, and 4 on the transport base 1.
[0037] In this embodiment, the first gripping assembly 2 includes two first gripping members 21 spaced apart along the length of the transport base 1. Each first gripping member 21 includes two first clamping jaws 211. The two first clamping jaws 211 are spaced apart along the length of the transport base 1, and the opening and closing directions of the first clamping jaws 211 are aligned with the width direction of the transport base 1. The two first clamping jaws 211 can respectively clamp at the two ends of the sand core 100, and the two first clamping jaws 211 cooperate with each other to effectively improve the handling stability of the sand core 100.
[0038] The sand core transporting mechanism also includes two supporting assemblies 7 respectively arranged at both ends of the transporting seat 1 in the length direction. Each supporting assembly 7 includes a supporting frame 71 movably arranged along the length direction of the transporting seat 1, a driving member 72 for driving the supporting frame 71 to move, and a supporting block 73 arranged at the bottom of the supporting frame 71.
[0039] The driving member 72 is a pneumatic cylinder, and the support block 73 is capable of supporting the lower portion of one end of the sand core 100 during the movement of the support frame 71, thereby cooperating with the two first clamping jaws 211 to transport the three-end sand core 100. During transportation, the two first clamping jaws 211 partially clamp two of the ends of the sand core 100, while the support block 73 moves and supports the lower portion of the other end to prevent the sand core 100 from shaking during transportation.
[0040] In this embodiment, the second grasping assembly 3 includes two second clamping jaws 31 arranged along the length direction of the transport base 1. The opening and closing directions of the two second clamping jaws 31 are the same as the width direction of the transport base 1. Each second clamping jaw 31 includes two oppositely arranged claw bodies 311, and the sides of the two claw bodies 311 are respectively provided with extension portions 312.
[0041] Among them, the two extension parts 312 are respectively integrally formed on the side parts in opposite directions of the two claw bodies 311, so that the two second clamping jaws 31 can increase the contact area with the sand core 100 through their extension parts 312, so that the two second clamping jaws 31 can clamp the sand core 100 with a longer length, thereby preventing the sand core 100 from shaking during transportation.
[0042] In this embodiment, the third gripping assembly 4 includes two third clamping jaws 41 spaced apart along the length of the transport base 1. The opening and closing directions of the two third clamping jaws 41 are aligned with the length of the transport base 1. The two third clamping jaws 41 can grasp smaller sand cores 100 that are outside the grasping range of the first and second gripping assemblies 2 and 3, further improving the efficiency of handling the sand cores 100. Furthermore, the opening and closing directions of the two third clamping jaws 41 are opposite to those of the first and second clamping jaws 211 and 31, thus preventing interference with the first and second clamping jaws 211 and 31.
[0043] In this embodiment, the transport base 1 is further provided with a second long groove 8 at both ends in the longitudinal direction thereof, and the second long groove 8 extends along the width direction of the transport base 1. The two second long grooves 8 can effectively reduce the weight of the transport base 1 and reduce the processing cost of the transport base 1.
[0044] In this embodiment, the first clamping jaw 211 , the second clamping jaw 31 and the third clamping jaw 41 are all pneumatic fingers, and their specific clamping principles are based on existing technologies and will not be described in detail here.
[0045] The implementation principle of the sand core transport mechanism in the embodiment of the present application is:
[0046] After the core making machine completes the core making, the transport seat 1 moves to the top of the core box, the first grabbing assembly 2 and the supporting assembly 7 cooperate with each other to grab and transport the multi-end sand core 100 on one side of the core box, the second grabbing assembly 3 grabs and transports the longer sand core 100 on the other side of the core box, and the third grabbing assembly 4 transports the small-sized sand core 100 in the middle of the core box. After the grabbing is completed, the transport seat 1 drives the first grabbing assembly 2, the second grabbing assembly 3 and the third grabbing assembly 4 away from the core box.
[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
