Description

Technical Field

[0001] This utility model relates to a clamping fixture, and more specifically, it relates to a clamping fixture based on a printer housing. Background Technology

[0002] In the manufacturing process of printers, the outer casing is a key structural component, and after molding, it often requires subsequent processing such as milling, drilling, or inspection. These processes usually require the casing to be precisely positioned and securely clamped onto a worktable or fixture to ensure processing accuracy and operational safety.

[0003] Currently, clamping fixtures for such sheet metal housing parts mostly employ a simple method of clamping with pressure plates and screws. While this method is structurally simple, it has shortcomings in actual operation. After processing, the workpiece often sticks to the locating pins due to factors such as cutting fluid and metal filings, making it difficult to remove and requiring manual prying, which is inefficient and poses safety hazards.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping fixture based on a printer housing.

[0006] The technical solution of this utility model is: A clamping fixture based on a printer housing includes a base. The top of the base is detachably connected to a plurality of clamping members around a workpiece. The number of clamping members is at least two and they are respectively disposed on opposite sides of the workpiece. The clamping members abut against the top of the folded edge of the workpiece. The top of the base is also provided with a plurality of positioning components. The positioning components include positioning members that cooperate with the bottom of the workpiece for positioning and a stripping structure that causes the workpiece to move away from the positioning members in a vertical direction.

[0007] The present invention is further configured such that the material stripping structure includes a fixing member fixedly connected to the top of the base and a material stripping member movably connected to the fixing member. The cross-section of the material stripping member is annular, and the positioning member is disposed in the middle of the material stripping member. The top of the fixing member is provided with a groove for accommodating the material stripping member. A plurality of elastic members are fixedly connected to the bottom wall of the groove. One end of the elastic member abuts against the bottom wall of the groove, and the other end of the elastic member abuts against the material stripping member. The elastic member has elastic deformation potential energy to drive the material stripping member so that the top surface of the material stripping member passes over the top surface of the positioning member.

[0008] The present invention is further configured such that the top end of the positioning member is rounded and cooperates with the positioning recess at the bottom of the workpiece.

[0009] The present invention is further provided that the top surface of both the fixing member and the stripping member is provided with a rubber layer.

[0010] The present invention is further configured such that the top of the base is provided with a plurality of limiting components on the outer periphery of the workpiece, the limiting components including an adjusting component and a limiting post provided on the adjusting component near the workpiece; the adjusting component is provided with an adjusting groove with a long strip cross section, the base is provided with a plurality of bolt mounting holes, the adjusting groove can communicate with the bolt mounting holes, and the adjusting component can be adjusted and fixed on the base by adjusting bolts.

[0011] The present invention is further configured such that the clamping component is a hydraulic rotary cylinder, and the cross-section of the pressure plate of the hydraulic rotary cylinder near the workpiece is trapezoidal.

[0012] The present invention is further configured such that a support member is provided on the top of the base on one side of the clamping member, the support member abuts against the bottom of the workpiece folded edge, and the support member is detachably connected to the top of the base by fastening bolts; when the clamping member abuts against the top of the folded edge, the support member is located below the clamping member.

[0013] The beneficial technical effects of this utility model are: By setting up a stripping structure and utilizing the cooperation between the elastic element and the stripping element, the elasticity of the elastic element drives the stripping element away from the groove, causing the workpiece base to move away from the fixing and supporting parts. Furthermore, the top surface of the stripping element passes over the top surface of the positioning element, causing the positioning element to disengage from the positioning recess. This makes it easier for the workpiece to detach from the base, ensuring work efficiency. It also prevents the workpiece from colliding with the positioning element when the robotic arm moves the workpiece horizontally during stripping, thus preventing damage and ensuring overall quality and service life. Moreover, if the positioning element becomes stuck due to cutting fluid, metal filings, or other factors, the elastic force of the elastic element ensures that the positioning element remains in the positioning recess during stripping, eliminating the need for additional tools.

Detailed Implementation

[0016] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0017] A clamping fixture based on a printer housing, such as Figures 1-4 As shown, the device includes a base 1. Several clamping components 2 are detachably connected to the top of the base 1 around the workpiece. The number of clamping components 2 is at least two and they are respectively set on opposite sides of the workpiece. Specifically, it can be set to three, with two set on one side of the workpiece and one on the other side. The clamping components 2 are hydraulic rotary cylinders. The cross section of the pressure plate of the hydraulic rotary cylinder near the workpiece is set in a trapezoidal shape, and the waists on both sides form a guide surface with a good guiding effect. Folded edges are set around the bottom of the workpiece. The clamping components 2 abut against the top of the folded edges. Several positioning components are also set on the top of the base 1. The positioning components include positioning components 3 that cooperate with the bottom positioning of the workpiece and a material removal structure. The material removal structure includes a fixing member 4 fixedly connected to the top of the base 1 and a material removal member 5 movably connected to the fixing member 4. The material removal member 5 has an annular cross-section. A positioning member 3 is located in the middle of the material removal member 5. The fixing member 4 is detachably connected to the top of the base 1 by bolts. The top of the fixing member 4 has a groove 41 for accommodating the material removal member 5. The positioning member 3 is fixedly connected to the top of the base 1 by bolts. The groove 41 has a through-hole for the positioning member 3 to pass through, and the top of the positioning member 3 extends out of the groove 41. Several elastic members 42 are fixedly connected to the inner bottom wall of the groove 41. The elastic members 42 are springs. One end of the elastic member 42 abuts against the inner bottom wall of the groove 41, and the other end of the elastic member 42 abuts against the material removal member. On component 5, elastic component 42 has elastic deformation potential energy to drive ejector component 5 so that the top surface of ejector component 5 passes over the top surface of positioning component 3; positioning component 3 can be positioning pin or positioning protrusion, and positioning recess is provided at the bottom of the workpiece to cooperate with positioning component 3. The outer peripheral wall of positioning component 3 abuts against the inner side wall of positioning recess, thereby ensuring the positioning accuracy of the overall workpiece. The top of positioning component 3 is rounded, which has a good guiding effect and makes it easier to place the workpiece. The inner peripheral wall of ejector component 5 is matched with the cross section of positioning component 3. Both fixing component 4 and the top surface of ejector component 5 are provided with rubber layer and contact the bottom surface of workpiece. The rubber layer has a certain buffering effect to prevent direct contact with workpiece and damage, thus ensuring the quality of workpiece. Several limiting components are provided on the top of the base 1, around the outer periphery of the workpiece. The number of limiting components is four, symmetrically arranged in pairs. Limiting components on the same side are located at both ends of the folded edge, with a gap between adjacent components. This allows the limiting components to surround the workpiece, initially restricting its position, finding its basic outline, and ensuring more accurate placement. This provides a certain degree of error prevention, ensuring the overall structure's lifespan while also maintaining worker efficiency. The limiting components include an adjusting component 6 and a limiting post 7 located on the adjusting component 6 near the workpiece end. The bottom of the positioning post 7 is provided with a threaded post, and the top of the adjusting component 6 near the workpiece is provided with a threaded hole that is threaded to the threaded post. The adjusting component 6 is provided with an adjusting groove 61 with a long cross section. The base 1 is provided with several bolt mounting holes. The adjusting groove 61 can communicate with the bolt mounting holes, and the adjusting component 6 can be adjusted and fixed to the base 1 by adjusting bolts 8. By setting the adjusting groove 61, when the adjusting bolts 8 are loosened, adjustment can be made, thereby fine-tuning the relative position of the positioning post 7, ensuring the limiting effect of the positioning post 7, and thus ensuring the stability of the overall clamping fixture for clamping the workpiece. The top of the base 1 is provided with a support member 9 that cooperates with the clamping member 2. The support member 9 abuts against the bottom of the workpiece folded edge. The support member 9 is detachably connected to the top of the base 1 by fastening bolts. When the clamping member 2 abuts against the top of the folded edge, the support member 9 is located below the clamping member 2. The support member 9 supports the clamping part to prevent excessive clamping force from damaging the product folded edge and to ensure product quality.

[0018] Working principle: The driving clamping member 2 moves towards positions that are further apart, allowing the workpiece to be placed bottom-down on top of the base 1. Due to the setting of the limiting posts 7, a preliminary positioning effect is achieved, determining the placement angle of the workpiece and ensuring that the positioning recess at the bottom of the workpiece corresponds better to the positioning member 3 at the top of the base 1. When the workpiece is positioned between the four limiting posts 7, pressing the workpiece causes its bottom to contact the release member, moving the release member 5 towards the groove 41 until the positioning member 3 extends out of the release member 5 and into the positioning recess at the bottom of the workpiece. At this point, the bottom of the workpiece's folded edges contacts the top of the support member 9, and the positioning recess contacts the outer peripheral wall of the positioning member 3, ensuring the accuracy of workpiece positioning and thus guaranteeing subsequent processing. To improve work precision, the driving clamping component 2 rotates towards the top of the folded edge until it contacts the top of the folded edge. After the driving clamping component 2 completes the pressing operation, the workpiece is stably fixed on the top of the base 1. After processing, it is only necessary to drive the clamping component 2 away from the top of the workpiece folded edge. At this time, the elasticity of the elastic component 42 drives the stripper 5 away from the groove 41, causing the workpiece base 1 to move away from the fixing component 4 and the support component 9. The top surface of the stripper 5 passes over the top surface of the positioning component 3, causing the positioning component 3 to disengage from the positioning recess. This makes it easier for the workpiece to be removed from the base 1, ensuring work efficiency. It also prevents the robotic arm from colliding with the positioning component 3 when using a series of tools such as a robotic arm for stripping, thus preventing damage to the workpiece and ensuring overall quality and service life.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
