Description

Technical Field

[0001] This utility model relates to the technical field of casting clamping equipment, specifically a casting removal gripper. Background Technology

[0002] Castings are shaped metal objects obtained through various casting methods, including cast steel, cast iron, cast copper, and cast aluminum. Castings are produced by pouring, injecting, suction, or other casting methods into a pre-prepared mold of smelted molten metal. After cooling, they undergo subsequent processing such as grinding to obtain objects with specific shapes, dimensions, and properties. However, the variety of casting types leads to inconsistent quality. Traditional clamping devices struggle to precisely control the clamping force when handling castings after they have been formed in the mold. If the casting is heavy and the clamping force is too weak, it may fall out and cause damage. Conversely, if the casting is small and the clamping point is thin, excessive clamping force may deform the casting. Furthermore, existing clamping devices often extend the gripping arms to facilitate force application, further complicating the operator's ability to accurately control the clamping force and impacting casting production quality.

[0003] To address this, a casting removal gripper is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a casting removal gripper to solve the problems in the prior art where the clamping force cannot be precisely controlled when clamping castings. Furthermore, the weight difference between different casting models leads to insufficient clamping force, resulting in unstable clamping force, or excessive clamping, causing deformation of the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A casting removal gripper includes an upper clamping rod and a lower clamping rod, which are hinged to each other. The gripper is characterized by comprising a clamping piece disposed at the front end of the upper clamping rod, a force control component disposed between the clamping piece and the upper clamping rod, a placement groove formed at the rear ends of the upper and lower clamping rods, an adjusting rod slidably connected within the placement groove, and an adjusting component disposed within the placement groove. The clamping piece engages with the front end of the lower clamping rod to clamp the workpiece. The force control component controls the clamping force between the clamping piece and the lower clamping rod. The adjusting component fixes the adjusting rod after it extends to a designated position within the placement groove.

[0007] Preferably, the force control component includes a control spring, a sliding groove, a sliding push rod, and a fixing unit. The sliding groove is formed inside the front end of the upper clamping rod, and the sliding push rod is slidably connected in the sliding groove. The two ends of the control spring are respectively connected to the right end of the clamping piece and the left front end of the upper clamping rod. The left end of the sliding push rod cooperates with the right end of the clamping piece. The fixing unit is located on the upper right side of the sliding groove, and the fixing unit is used to fix the sliding push rod at a designated position.

[0008] The purpose of this design is that, after the sliding push rod is fixed in the designated position, when clamping the casting, the front section of the lower clamping rod and the clamping plate clamp the edge of the casting, and then the rear ends of the upper and lower clamping rods are pinched together, so that the front ends of the upper and lower clamping rods come closer to each other. During this process, the upper clamping rod will continuously squeeze the control spring between the clamping plate, thereby achieving slow clamping of the casting. When the clamping requirement is met, the left end of the sliding push rod in the front end of the upper clamping rod will abut against the right end of the clamping plate, effectively preventing further clamping of the casting and preventing the casting from being over-clamped, causing deformation or leaving clamp marks.

[0009] Preferably, the fixing unit includes a fixing groove, a fixing block, a fixing pin, a fixing slot, a fixing baffle, and a fixing spring. The fixing groove is formed inside the upper clamping rod, the fixing block is slidably connected inside the fixing groove, the fixing pin is located at the rear end of the fixing block, the fixing slot is located at the front end of the sliding push rod, the fixing baffle is located on the side of the fixing block, the two ends of the fixing spring abut against the front end of the fixing baffle and the inner wall of the upper clamping rod, respectively, and the fixing pin cooperates with the fixing slot.

[0010] The purpose of this design is that when the position of the sliding push rod needs to be adjusted, simply pull the fixing block to cause the fixing block to pull the fixing pin out of the fixing slot, thereby unlocking the sliding push rod and adjusting its position. During the process of the fixing pin being pulled out of the fixing slot, the fixing block will also move the fixing baffle and squeeze the fixing spring. When the sliding push rod moves to the appropriate position, the operator only needs to release the fixing block, allowing the fixing block to reset under the elastic force of the fixing spring, and then allowing the fixing pin to re-insert into the fixing slot.

[0011] Preferably, the front end of the fixing block is provided with a pin pull rod.

[0012] The purpose of this design is to allow the operator to easily pull out the retaining block using the latch lever.

[0013] Preferably, a friction pad is provided on the right side of the front end of the lower clamping rod.

[0014] The purpose of this design is that the friction pad can increase the friction between the lower clamping bar and the casting, effectively preventing the casting from falling off during clamping.

[0015] Preferably, the adjusting component includes an adjusting groove, an adjusting block, an adjusting spring, and an adjusting slot. The adjusting groove is located on the side of the placement groove. The adjusting block is slidably connected in the adjusting groove. The two ends of the adjusting spring abut against the end of the adjusting block away from the adjusting rod and the inner wall of the adjusting groove, respectively. The adjusting slot is located at the front end of the adjusting rod, and the adjusting block cooperates with the adjusting slot.

[0016] The purpose of this design is that after the adjusting rod extends to the appropriate length of the upper and lower clamping rods, the adjusting slot on the adjusting rod is aligned with the position of the adjusting block at its location. Under the action of the adjusting spring, the adjusting block is reset and inserted into the adjusting slot, thus achieving simple fixation of the adjusting rod.

[0017] Preferably, an adjusting rod is provided at the rear end of the adjusting rod.

[0018] The purpose of this design is to make it easier for the operator to pull the adjusting rod, allowing for more convenient adjustment of its position within the upper or lower clamping rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] By installing a clamping plate on the upper clamping bar and a force control component between the clamping plate and the upper clamping bar, the operator can prevent excessive clamping force when clamping the casting, which could lead to damage or deformation of the casting. Through the adjusting rod and adjusting component, the operator can adjust the lever arm of the upper and lower clamping bars as needed. When clamping heavier castings, the lever arm can be appropriately increased, and when the clamping space is small, the lever arm can be appropriately decreased, making the gripper more versatile.

[0027] To ensure a clear and complete description of the technical solutions in the embodiments of this utility model, and to make the features and advantages more apparent and understandable, the specific implementation methods of this utility model are described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] Please see Figures 1 to 4 This utility model provides a casting removal gripper, including an upper clamping rod 1 and a lower clamping rod 2, which are hinged to each other. It includes a clamping piece 3 at the front end of the upper clamping rod 1, a force control component 4 between the clamping piece 3 and the upper clamping rod 1, a placement groove 5 at the rear end of the upper clamping rod 1 and the lower clamping rod 2, an adjusting rod 6 slidably connected in the placement groove 5, and an adjusting component 7 within the placement groove 5. The clamping piece 3 cooperates with the front end of the lower clamping rod 2 to clamp the workpiece. The force control component 4 controls the clamping force between the clamping piece 3 and the lower clamping rod 2. The adjusting component 7 fixes the adjusting rod 6 after it extends to a designated position in the placement groove 5.

[0030] Please see Figures 2 to 4Specifically, the force control component 4 includes a control spring 41, a sliding groove 42, a sliding push rod 43, and a fixing unit 44. The sliding groove 42 is located inside the front end of the upper clamping rod 1, and the sliding push rod 43 is slidably connected within the sliding groove 42. Both ends of the control spring 41 are connected to the right end of the clamping piece 3 and the left front end of the upper clamping rod 1, respectively. The left end of the sliding push rod 43 engages with the right end of the clamping piece 3. This engagement means that when the sliding push rod 43 is fixed to the designated position, when clamping the casting, the front section of the lower clamping rod 2 and the clamping piece 3 are used to clamp the edge of the casting, and then the upper clamping rod is tightened. The upper clamping rod 1 and the lower clamping rod 2 are positioned so that the front ends of the upper clamping rod 1 and the lower clamping rod 2 are brought closer together. During this process, the upper clamping rod 1 will continuously press the control spring 41 between the clamping plate 3, thereby achieving slow clamping of the casting. When the clamping requirement is met, the left end of the sliding push rod 43 in the front end of the upper clamping rod 1 will abut against the right end of the clamping plate 3, effectively preventing further clamping of the casting and preventing the casting from being over-clamped, causing deformation or leaving clamp marks. The fixing unit 44 is set on the upper right side of the sliding groove 42. The fixing unit 44 is used to fix the sliding push rod 43 in a designated position.

[0031] Please see Figure 3 Specifically, the fixing unit 44 includes a fixing groove 441, a fixing block 442, a fixing pin 443, a fixing slot 444, a fixing baffle 445, and a fixing spring 446. The fixing groove 441 is formed inside the upper clamping rod 1, the fixing block 442 is slidably connected to the fixing groove 441, the fixing pin 443 is located at the rear end of the fixing block 442, the fixing slot 444 is located at the front end of the sliding push rod 43, the fixing baffle 445 is located on the side of the fixing block 442, and the two ends of the fixing spring 446 abut against the front end of the fixing baffle 445 and the inner wall of the upper clamping rod 1, respectively. The sliding push rod 43 can also be engraved with clamping force scale values ​​(not shown in the figure). The specific values ​​can be set according to the stiffness coefficient of the control spring 41. The clamping force scale values ​​can effectively reflect the control spring. Part 41 applies clamping force to the casting. The fixing pin 443 engages with the fixing slot 444. This engagement means that when the position of the sliding push rod 43 needs to be adjusted, only the fixing block 442 needs to be pulled, causing the fixing block 442 to drive the fixing pin 443 out of the fixing slot 444, thereby unlocking the sliding push rod 43 and adjusting its position. During the process of the fixing pin 443 being pulled out of the fixing slot 444, the fixing block 442 also drives the fixing baffle 445 to move and presses the fixing spring 446. When the sliding push rod 43 moves to the appropriate position, the operator only needs to release the fixing block 442, allowing the fixing block 442 to reset under the elastic force of the fixing spring 446, thereby allowing the fixing pin 443 to re-insert into the fixing slot 444.

[0032] Please see Figure 4Specifically, the front end of the fixing block 442 is provided with a pin pull rod 4421, which makes it easy for the operator to pull out the fixing block 442. The right side of the front end of the lower clamping rod 2 is provided with a friction pad 21, which can increase the friction between the lower clamping rod 2 and the casting, effectively preventing the casting from falling off during clamping.

[0033] Working principle: When clamping a casting, given the casting model and approximate weight, to prevent excessive clamping that could deform or damage the casting, the operator only needs to pull out the fixing block 442. This causes the fixing block 442 to pull the fixing pin 443 out of the fixing slot 444, simultaneously causing the fixing baffle 445 to press against the fixing spring 446. Then, the operator moves the sliding push rod 43 to a suitable position. When the clamping plate 3 clamps the casting and presses against the control spring 41, the reaction force of the control spring 41 on the clamping plate 3 is sufficient to meet the clamping requirements of the workpiece without over-clamping. At this time, the right end of the clamping plate 3 is in contact with the left end of the sliding push rod 43, preventing the operator from further clamping the workpiece by operating the rear ends of the upper clamping rod 1 and the lower clamping rod 2, which could lead to over-clamping and damage or deformation of the workpiece.

[0034] Example 2

[0035] Please see Figures 2 to 5 This invention provides a casting removal gripper, including an adjusting component 7. The adjusting component 7 includes an adjusting groove 71, an adjusting block 72, an adjusting spring 73, and an adjusting slot 74. The adjusting groove 71 is located on the side of the placement groove 5. Multiple adjusting grooves 71 are provided, each corresponding to an extension position of an adjusting rod 6. The number of adjusting grooves 71 can be set according to the user's needs. Three are shown in the accompanying drawings. Each adjusting groove 71 is provided with an adjusting block 72 and an adjusting spring 73. The adjusting block 72 is slidably connected in the adjusting groove 71. The two ends of the adjusting spring 73 abut against the end of the adjusting block 72 away from the adjusting rod 6 and the inner wall of the adjusting groove 71, respectively. The adjusting slot 74 is located at the front end of the adjusting rod 6, away from the adjusting block 72 and the adjusting spring. One end of 73 is a semi-circular ball head. The purpose of this design is that when it is necessary to adjust the extension length of the adjusting rod 6, only a pulling force needs to be applied to the adjusting rod 6 to move it backward relative to the upper clamping rod 1 or the lower clamping rod 2. When the adjusting rod 6 moves the adjusting groove 71, the adjusting block 72 slides out of the adjusting slot 74 along the semi-circular ball head and presses the adjusting spring 73. The adjusting block 72 cooperates with the adjusting slot 74. The cooperation here means that after the adjusting rod 6 extends to the appropriate position length of the upper clamping rod 1 and the lower clamping rod 2, the adjusting slot 74 on the adjusting rod 6 is aligned with the position of the adjusting block 72. Under the action of the adjusting spring 73, the adjusting block 72 resets and inserts into the adjusting slot 74, realizing simple fixation of the adjusting rod 6.

[0036] Please see Figure 2 Specifically, an adjusting lever 61 is provided at the rear end of the adjusting lever 6. The adjusting lever 61 makes it easier for the operator to pull the adjusting lever 6, so that the adjusting lever 6 can be more easily adjusted to the position within the upper clamping lever 1 or the lower clamping lever 2.

[0037] The rest of the structure is the same as in Example 1.

[0038] Working principle: When using the gripper to clamp castings, if the casting is too heavy and the lever arm of the upper clamping rod 1 and lower clamping rod 2 needs to be adjusted, or if the operating space is too small and the lever arm of the upper clamping rod 1 and lower clamping rod 2 needs to be appropriately reduced, the operator only needs to move the adjusting rod 6 forward or backward relative to the upper clamping rod 1 or lower clamping rod 2, so that the adjusting rod 6 drives the adjusting slot 74 to move until it is adjusted to a suitable position. At this time, the adjusting block 72 in the adjusting groove 71 is re-inserted into the adjusting slot 74 under the action of the adjusting spring 73, thereby adjusting the position of the adjusting rod 6, and thus adjusting the lever arm of the upper clamping rod 1 and lower clamping rod 2. This allows the gripper to adjust the lever arm appropriately according to the operator's needs when clamping castings. When clamping heavier castings, the lever arm can be appropriately enlarged to make clamping easier, and when the clamping space is small, the lever arm can be appropriately reduced to make the clamping angle easier to adjust. This allows the gripper to adjust the clamping of castings appropriately according to the operator's needs.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
